For little money you can build a macro keyboard to send commands or text modules to a Mac or PC. We show you how to do it step by step.
Entry into microcontroller programming: DIY macro keyboard The ingredients The Arduino project Alternative microcontroller Blink -Sample project, solder rows of pins Simulate key, read out keypad Article in Mac & i 13/2020 read Getting started with programming microcontrollers has never been so cheap and easy as it is today – thanks to Arduino. After completing the project, tap on an external keypad on one of the 16 Keys to execute a custom keyboard macro and to send it to macOS or Windows programs as if one were normal keyboard connected, which you would have to operate by hand. In this way you can, for example, place special characters hidden in the shallows that you need frequently on a key or insert complex text modules with a tap. This is made possible by microcontrollers that connect to the computer like a USB keyboard.
Input devices such as keyboard and mouse are now connected either via USB or Bluetooth LE. The HID protocol (Human Interface Device) is used in both cases, which was originally conceived for USB. All current operating systems recognize HID devices such as keyboards and mice without the need for a special driver.
If you already have basic electronics, especially a soldering iron, you can use our instructions Build your own individual macro keyboard with USB or BLE for very little money. If you want to buy a soldering device, you shouldn’t save too much on it – even if the work with it for our project is limited to soldering rows of pins. A soldering iron is suitable for many other projects.

LG Display is continuing its trend of reimagining the future of screens at CES 2021 with a new transparent TV. The panel is a 55-inch OLED, but its transparent design lets you see through it even when it’s turned on and displaying an image.
The screen achieves 40 percent transparency, LG Display says, which is an improvement over past transparent LCDs the company claims achieved only 10 percent transparency.
LG imagines the screen sitting at the foot of a bed, where it can rise up partially or in full to show information or videos while retaining a view of the other side of the screen. The panel as it’s designed now has built-in speakers in the form of LG Display’s Cinematic Sound OLED (CSO) technology, which uses vibrations of the screen to produce audio. It’s the same audio system found on LG’s other OLED prototype announced at CES this year, a bendable gaming monitor that can transform from flat to curved.
LG says the transparent OLED set can also be moved around the home if you’d like to position it somewhere else (if it were something you could actually buy, which you cannot right now).

The company sees this as both a smart home device and one that could one day be used in public settings, like in restaurants and on public transportation.
“Transparent OLED is a technology that maximizes the advantages of OLED and can be used in various places in our daily lives, from stores, shopping malls, and architectural interiors to autonomous vehicles, subway trains, and aircraft,” Jong-sun Park, LG Display’s senior vice president and head of commercial business, said in a statement. “It will grow into a next-generation display that can change the existing display paradigm.”

This isn’t the first transparent display to make a debut at CES; we’ve seen Samsung’s transparent OLED screens before, and Panasonic showed off a prototype transparent display back in 2016 (though it was only HD). And it’s not even LG’s first transparent OLED — the company announced last month it’s started developing see-through OLED sliding doors for office buildings and commercial spaces. LG also created a 77-inch curved transparent OLED back in 2017 that it imagined could be used for signage or advertising.
But this is LG Display’s first screen of this type it’s made strictly as a TV that would actually go in someone’s home, and not just something you’d see in a futuristic shopping center or some other commercial venue.
This is just one of many in a long line of LG Display experimental prototypes, some of which do indeed become real products you can buy. The company has made waves at past CES showcases with various iterations of its rollable OLED technology, while a commercial version of the TV using the tech finally went on sale in South Korea in October of last year for an eye-popping $87,000.
Unfortunately, there’s no indication right now that LG’s new transparent OLED TV will become a real product at some point in the future or how much it might cost if it does.
LG Display has shared video of its new 48-inch OLED gaming TV that can bend from a flat display to a curved one with the push of a button, and seeing it in motion is fascinating. Check it out at the top of this post.
The flexible display orientations could let you watch TV with the flat orientation and play games with the curved one, for example. The company’s video also shows off how the screen could be used for a racing game with a first-person perspective in the cockpit, which seems like another practical use of a flexible TV to me. If you prefer to play racing games with a flat screen, you can keep the TV that way or opt to curve it if you find that more immersive.
The TV can bend up to a radius of 1,000mm, has up to a 120Hz refresh rate, and offers a variable refresh rate ranging from 40Hz to 120Hz. It also has LG’s Cinematic Sound OLED (CSO) technology, which vibrates the display to create sound in lieu of speakers. LG has shown off similar technology before with prototype TVs and last year’s LG G8, but since CES is virtual this year, we can’t personally vouch for how well the CSO technology actually works in this new display.
If you just want to watch the screen change from flat to curved and back again, we made this hypnotic GIF for you. Enjoy.
Samsung never enabled 120Hz mode at 1440p+ resolution for the Galaxy S20 family, despite what some early rumors claimed. This year it’s looking like the new LTPO panel on the Galaxy S21 Ultra will finally enable 120Hz at the top resolution. The two vanilla S21 will get 1080p+ displays side-stepping the issue. All of this is just rumors for now, of course, the official announcement isn’t until next week.
But while we wait we wanted to ask which do you prefer – resolution or refresh rate? A 1080p+ high refresh rate (HRR) display and a high resolution one? You can’t have both as a 4K 144 Hz display may sound awesome on paper, but will murder the battery in no time.
High refresh rate vs. high resolution
It’s not just the Galaxys either, the Sony flagships are in the same boat, for example. The Xperia 1 II boasts the only 4K OLED display in the mobile market, but it has a 60Hz refresh rate. The Xperia 5 II is Sony’s first phone with a HRR display, but it has 1080p+ resolution.
For gaming phones the answer seems to be clear – fast-paced games benefit from refresh rate much more than resolution. For multimedia, the opposite is true. Which is option is better-suited to your needs?
We have a feeling we can guess the answer to this next question, but we’ll ask anyway. Flat screens vs. curved screens, which is better?
Curved screens vs. flat screens
A curved screen makes the phone narrower and is good for the swipe gestures of modern Android. It also looks so much better.
A flat screen is easier to guard with a case and protector. Makers are pushing curved panels as a premium feature, usually reserved for the top models (the upcoming S21 series will be an example of that). But sometimes makers get caught up in fads despite protestations from fans.
Panasonic has undertaken in recent years the road of maximum compatibility and next to the formats Dolby Vision, Dolby Vision IQ, HDR 10 + and HLG, on the new top of the range we also find support for the new ‘HDR format 10 + Adaptive ‘. Panasonic JZ 2000 will be compatible with 4K video signals 120 p, VRR and ALLM
by Roberto Colombo published on 10 January 2021 , at 09: 01 in the Audio Video channel Panasonic OLED 4K HDR
Also Panasonic presented a preview of the digital edition of the CES 2021 , its biggest news in the TV world, revealing the ‘OLED top of the range JZ 2000 . The Japanese brand has been more conservative than the competition and continues to offer its top of the range in formats from 65″ is 55 “, without scaling on formed by 77 “and 83 “on which competition has pushed.
New DSP HCX Pro AI
As also done by Sony , Panasonic worked to squeeze the OLED panel to the maximum and in the presentation to the press showed a peak brightness with a real measurement equal to 820 NIT . Similar to that of the competitors, the path taken to update the processor, now called HCX Pro AI, with the addition of artificial intelligence, able to exploit a large database of images to understand which processing to apply to each type of content .
The new processor brings more power and speed, with positive implications – for example – on the input lag, which passes, for 4K content 60 p, a 14 ms compared to 21 ms from last year’s series. Not only that, upon arrival on the market Panasonic JZ 2000 will be compatible with 4K video signals 120 p, VRR and ALLM .
HDR 10 + Adaptive
Panasonic has undertaken in recent years, from the landing of HDR on TVs, the path of maximum compatibility and next to Dolby Vision, Dolby Vision IQ, HDR formats 01 + and HLG, on the new range we also find support for the new format ‘ HDR 10 + Adaptive ‘, born as a response to Dolby Vision IQ and which uses an ambient lighting sensor to optimize the management of luminance levels based on the amount of light in the room.
Panasonic has also worked on the audio and at the hardware level has added some side speakers to enhance sound immersion. The drivers of the integrated soundbar and the rear speakers oriented upwards to take advantage of the bounce of sounds on the ceiling remain a fixed point. The new Panasonic JZ TV 2000 therefore promises to take a further step forward in content reproduction Dolby Atmos , ensuring an enveloping sound scene even without the need for external speaker systems. The audio system bears the label “ Tuned by Technics “. Also at the audio level, the interesting possibility of connecting two Bluetooth devices at the same time is noted, for example for evening viewing in company when the rest of the family sleeps. Among other functions, also the interaction with the voice assistants without the need for the remote control.
For more technical specifications it will be necessary to wait until next March, when Panasonic will also the rest of the products that will make up the TV range 2021.
Lypertek is a small Chinese manufacturer of personal audio products. Last month, we reviewed the Lypertek Levi, the company’s latest TWS earbuds at an affordable price. The Levi offered great performance for the price and quickly became one of our favorites in their price category.
Today, however, I am checking out the product that put the company on the map. The Lypertek Tevi are the popular TWS earbuds that received a ton of critical acclaim since their release. The Tevi feature graphene drivers, along with features such as aptX TWS+ and IPX7 rating for water-resistance. They have received a lot of praise for their audio quality and I was really looking forward to trying them.
So after a month of use, here are my thoughts on these popular earbuds.
Design
The Lypertek Tevi have a fairly standard earbud design. The left and right earbud are nearly identical, with only a very slight angle to the ear tip to separate them from each other. However, this would be barely felt in your ear if you wear them wrong and you can also just put them inside any slot in the charging case. There is also no way to tell them apart in the dark.
The earbuds have a single physical button on the outside on each side. This one button handles all the playback and volume control duties, which can be customized through the companion app.
The earbuds come with four sets of ear tips, three of which are silicone in different sizes. The fourth is made out of foam, which isn’t super common in this $90 price range.
The case design is also fairly standard but with a fabric covering the plastic shell. It comes with a little artificial leather strap attached but can be removed. The front has LED indicators to show the status for the battery inside the case. On the back is a USB-C port for charging.
The Lypertek Tevi case does not support wireless charging like its newer and cheaper sibling, the Levi.
The Tevi case is not well built, even though it looks and feels nice to the touch thanks to the fabric cover. The lid feels a bit loose around its hinge and slides around when closed. The case is also unbelievably finicky to open; there is no lip or proper gap on the front to dig your thumb in and it keeps sliding off the smooth fabric cover. It’s also one of those annoying lids that doesn’t open wide and gets in the way while trying to pull the earbuds out.
Getting back to the earbuds, the Tevi have IPX7 water-resistance, enough for a bit of rain or sweat. The earbuds aren’t too big, so they don’t visibly stick out a lot from your ears but they are big enough that you can’t wear them in bed and lie on your side.
Comfort
I found the Lypertek Tevi to be quite comfortable. I tried them with both, the silicone as well as the foam ear tips, and found that they were equally comfortable.
I would rank the silicone comfort to be a bit on the higher size; if you find one that fits you perfectly, then it will always feel great and you can barely even tell that you are wearing the earphones anymore. With foam, the advantage is that they expand to fit your ears. While this achieves a good seal, once the foam has fully expanded it can put some pressure on your ear canal. It’s not uncomfortable but it doesn’t let me forget that I’m wearing them.
Overall, I think the Lypertek Tevi should be comfortable for most people.
Features and software
The Lypertek Tevi have a single 6mm graphene driver. Graphene is known for being strong relative to its weight, which means you can have a sturdy driver that’s relatively lightweight, an advantage when it comes to moving objects.
The Tevi support Bluetooth 5.0 but no multi-device pairing. Audio transmission uses SBC, AAC, or aptX.
The Tevi supports Qualcomm TWS+, which allows both earbuds to connect directly to the phone instead of a master-slave configuration where one earbud connects to the source and the other to the first earbud. Having both connect directly to the source reduces latency and uneven battery discharge. It also prevents the issue where rapidly increasing or decreasing the volume causes it to happen in one ear first and the second ear after a short delay.
Lypertek also offers a companion app, available on iOS and Android. The app does basic things, such as being able to EQ the sound or upgrade the firmware. You can also change the control scheme for the buttons on the earbuds.
Lypertek Tevi app
One thing I wish the app did was let you disable or turn down the announcements when the earbuds pair with your device. Every time the earbuds pair, you get a loud announcement in each ear saying “Connected”. It is genuinely one of the loudest announcement sounds I’ve heard on any Bluetooth product and makes you think the people at Lypertek are partially deaf for thinking this would be acceptable. Now every time I pull them out of the case, I let them sit for ten seconds for them to pair and make the announcement before putting them on.
Performance
Audio
The Lypertek Tevi have excellent audio quality for their price and product category. You get fantastic tonal balance and personally one of the most pleasing tunings I’ve heard in this price range. The Tevi can be paired with a wide variety of content and they always come out shining.
Starting with the low-end, the Lypertek Tevi have a well-balanced and enjoyable bass response. Frequencies are boosted in the mid-bass region by a few decibels, which isn’t enough to make them overpower the mids or the upset the tonal balance but lets you get that extra kick and slam out of percussion instruments and bass drops.
The bass is a lot more rounded and potent with the silicone ear tips. However, switching to the foam tips made the low-end response more restrained in my experience. Personally, I preferred this as it made the sound even closer to neutral than it already was without making it anemic or analytical. It’s worth experimenting with the different tips to see what sort of sound you get.
The mid-range is the highlight of the sound for me. With budget earbuds, more often than not it’s a given that the mid-range is going to be either overshadowed by the mid and high-bass or just dialed back artificially for that V-shaped sound. However, the mids on the Lypertek Tevi are out in full force, with excellent presence and clarity throughout the mix. String instruments and smaller percussion instruments have a wonderful timber and sound full-bodied. Vocals have natural tonality that lets you appreciate the voice as it stands proudly in the mix.
Fortunately, the good news doesn’t end there, as the Tevi also have a very good high-end response. Getting a good treble performance is a tightrope walk as it’s a much harder region to tune precisely and slight deviations can cause the sound to either lose detail or become too bright. The Lypertek Tevi manage this tightrope walk quite well, with the high-end having sufficient resolution and detail, along with a bit of sizzle and air at the top without sounding harsh or sibilant. Higher pitched female vocals, guitar strings, and high hats all have a good clean sound without overpowering the mix or having a metallic tinge.
But what impressed me in particular was the imaging and soundstage. Neither of these are strong suits of in-ear earbuds as they don’t quite engage the outer ear to give you the sensation of listening to a good pair of speakers. However, it seems there is some audio processing magic going on with the Lypertek Tevi, as they produce some of the best imaging and soundstage performance I’ve heard on wireless and on par with good wired earbuds.
The earbuds also have the uncanny ability to disappear in the sound sphere. Now, to be fair, the soundstage isn’t as wide as good open back headphones, let alone loudspeakers, but it extends a good bit outside the confines of your head and the imaging is able to place the objects exceedingly well around this little virtual sphere.
If this really is audio processing magic, it’s one of the best I’ve heard and at no point comes across as artificial sounding or over-processed. That it sounds like good wired audio is the best compliment I can give it.
Overall, I was really impressed with the audio quality on the Lypertek Tevi. If these were $200-300 full-sized wired headphones, the audio quality would have been good, if somewhat unremarkable. But the fact these are not just in-ear earbuds but also truly wireless earbuds at $90 is crazy. This is pure technical brilliance on display here that too at a scarcely believable price.
Microphone
The Lypertek Tevi have mediocre recording quality. The audio resembles that from an old landline telephone. It’s audible and your callers won’t have issue discerning what you’re saying but the sound itself has a tacky, compressed quality to it. Background noise isolation is also average at best. Adequate for short calls but not if voice calls are super important to you.
Latency
The Lypertek Tevi have good latency performance when used with aptX and TWS+. When testing with AAC, the latency was still acceptable. The delay was more noticeable to me but wasn’t experience breaking and most people won’t notice it. Overall, the Lypertek Tevi are perfectly viable for watching video content and some casual gaming but serious gamers may still want to invest in a wired headset, especially if they also plan on using voice chat.
Noise-cancellation
The Lypertek Tevi don’t have active noise-cancellation. However, they exhibited excellent passive noise isolation, especially when using the foam ear tips. The earbuds alone, with nothing playing, can drown out most ambient noise in a typical home or office environment.
With audio playing, you really need something loud to happen right next to you for you to be able to notice it. This level of isolation, however, may not be safe if you plan on wearing them outdoors and there’s also no passthrough mode that some earbuds have.
Connectivity
The Lypertek Tevi had reliable connectivity throughout the test period, which was just over a month at the time of writing. While I’d like to say this is the norm, it really isn’t and even modern Bluetooth products from large manufacturers often exhibit some hiccups every now and then. So for the Lypertek Tevi to remain rock solid throughout was something of an achievement.
Battery
The Lypertek Tevi have a promised battery life of 10 hours of continuous usage when using SBC. My testing was conducted using aptX and so I managed 8.5 hours of continuous playback. For TWS earbuds, this is a good, if not exceptional result.
What’s somewhat disappointing is the fast charge time. After 10 minutes of charging from flat, the earbuds only played for an hour before shutting down, which is easily the lowest result I’ve had so far. No wonder Lypertek doesn’t make any fast charge claims.
As mentioned before, the Lypertek Tevi case doesn’t support wireless charging so wired charging is your only option.
Conclusion
The Lypertek Tevi are priced at $90 and are now my favorite budget wireless earbuds. Whatever engineering/incantations Lypertek had to do to make them sound the way they do was worth it, because they sound incredible for the price.
They are also comfortable, have good design, build quality, battery life, latency, and passive noise isolation. The only thing that sticks out is the microphone performance, and even that should be adequate for most people.
If you are still in the wired audio camp, that’s understandable. For around the same price, you could get something like the MoonDrop Starfield, or pay a bit less and get the Tin T3 or BLON BL-03 and you’d be very happy with those. But products like Lypertek Tevi show that you can now have technically great sound that is still affordable but without any wires. It’s quite impressive and I can’t wait to see how much better wireless earbuds get in the future.
I’ve personally really enjoyed using these for the past several weeks, even when I’ve had other, more expensive things lying around. I plan on getting a pair of my own as soon as I hand back the review unit and using them as my daily driver for the foreseeable future.
Sony has announced two new wireless speaker systems, the SRS-RA5000 and the SRS-RA3000. Both speakers are designed with providing a room-filling sound in an indoor setting and feature Sony’s proprietary 360 Reality Audio feature.
The more expensive of the two, the RA5000 has seven speaker system with three up-firing drivers, three front-facing drivers and an internal woofer. The up and side-firing design creates a uniform sphere of sound around the speaker regardless of its position around the room. The RA5000 also has a manual sound calibration feature, which lets it tune its audio to its current position.
The cheaper and smaller RA3000 has a triple-driver layout consisting of two tweeters that project sound in an arc through a long strip and a single woofer. There are also two passive radiators for additional low-end response.
The RA3000 also has a humidity-resistant design, which allows it to be placed in environments such as bathrooms and kitchens, which is something the RA5000 cannot do. The RA3000 can also auto calibrate itself to its surroundings, which is also oddly missing from the RA5000.
Both speakers feature Bluetooth and Wi-Fi connectivity. Wi-Fi allows you to stream content from Spotify using the Spotify Connect feature or you can use the Chromecast integration to cast audio.
Both speakers also have Amazon Alexa and Google Assistant. However, this doesn’t make them smart speakers themselves but they can integrate with other smart devices within your home and you can also make them play audio along with your other smart speakers. If you want to play something on these speakers using your voice, you would need an Amazon or Google smart device and then tell it to play audio on these speakers.
The speakers only seem to be available in UK and Europe for now, retailing at £500/€599 for the RA5000 and £280/€359 for the RA3000. Both will be available in February 2021. Availability for North America would be announced later.
The 2021 Sony Bravia lineup comes in LED and OLED varieties ranging from 50-inches to 100-inches and features HDMI 2.1, standard Google TV interface as well as the brand’s new Cognitive Processor XR. HDMI 2.1 is a big addition that is essential for PS5 and Xbox Series X owners who want to game in full 4K at 120Hz.
Arguably the biggest new feature with the new TVs is the new Cognitive Processor XR – Sony’s latest image and audio processing chip which analyzes multiple elements on screen simultaneously and adjusts the parameters for the optimal image quality. Audio is another focus of the new chip as it can analyze sound position from the signal and match it to the picture while also upscaling traditional sound elements to 3D surround sound.
While conventional Artificial Intelligence (AI) can only detect and analyze picture elements like color, contrast and detail individually, the new processor can cross-analyze an array of elements at once, just as our brains do.
By doing so, each element is adjusted to its best final outcome, in conjunction with each other, so everything is synchronized and lifelike – something that conventional AI cannot achieve.
The new TVs also come with variable refresh rate support, auto low latency mode and enhanced audio return channel support. They all support Dolby Vision HDR too. The flagship Master Series Z9J 8K LED model comes in 85-inch and 75-inch sizes while the A90J Master Series 4K OLED is available in 55”, 65” and 83” variants. The A80J 4K OLED ranges from 55” to 77” while the lower tier X90J 4K LED model tops out at 100-inches.
Pricing or availability details were not detailed yet but should be made public at CES next week.
Sony has announced two new wireless speakers, and they pack plenty of tech to fill your room with sound.
The SRS-RA5000 and SRS-RA3000 both support Sony 360 Reality Audio and feature Immersive Audio Enhancement. 360 Reality Audio is a spatial sound format that allows for 360-degree sound, while Immersive Audio Enhancement upscales stereo sound so it has a surround effect.
But these aren’t the only strings to these speakers’ bows. The RA5000 (the pricier of the two) is also certified for Hi-Res Audio. It’s the most interesting-looking of the two and boasts three up-firing speakers to spread music vertically, and three middle speakers to handle horizontal duties.
Inside the RA3000 is a full-range speaker, an omni-diffuser that spreads sound throughout the room in every direction and a dual passive radiator to handle bass. Overlapping beam tweeters form an upward wavefront, delivering sound vertically and supposedly making audio more immersive.

Both speakers can be calibrated to your room, too. On the RA5000, you hold down a button and the speaker conducts a “detailed sound calibration adjustment” for its surroundings. The RA3000 calibrates itself automatically, with no button presses needed.
They adjust the volume track-by-track to ensure it’s consistent, and they work with Google Assistant, Chromecast built-in and Alexa devices, giving them voice controls. Bluetooth and wi-fi come as standard, and they work as multi-room speakers, so you can play the same or different tunes in each room.
They work with compatible Sony TVs too, beefing up the telly’s audio. Finishes? Both come with a black body and contrasting copper highlights, while the RA3000 also comes in a light grey fabric body with silver accents. The RA3000 is humidity resistant too, making it perfect for the bathroom or kitchen.
Both go on sale in February. The SRS-RA5000 will cost £500/€599, and the SRS-RA3000 £280/€359.
Sony has also added video streaming to its 360 Reality Audio offering. The aim is to recreate the feel of a live gig – very timely, given that music venues around the world are currently closed. It’s currently in talks with major music labels and service providers to begin streaming video content later this year.
To showcase the new feature, Sony is putting on a concert with musician Zara Larsson on Monday night. To watch, you’ll need the Artist Connection app on your device.
Sony is also looking to expand its library of compatible 360 Reality Audio devices, and to help it achieve this, the company has announced it will start to license out certain technologies.
There is a headphones personalization technology that analyzes the listener’s hearing characteristics, and also technology that enable smartphones and automotive vehicles to play 360 Reality Audio.

What’s better than an OLED TV in your living room? How about a huge OLED display in your car. Mercedes-Benz has made quite the splash at CES in recent years (remember the Avatar-inspired AVTR concept from last year?) and 2021 is no different.
The massive MBUX Hyperscreen is an optional feature for the EQS, the upcoming all-electric luxury car from Mercedes-Benz.
It measures 141cm wide and in keeping with an early 4K TV trend, it’s also curved. The display stretches across the front of the car almost from A-pillar to A-pillar.
There are 12 actuators carefully positioned beneath the screen that give haptic feedback with every press. It’s claimed that special coatings for the screen’s cover plate help to reduce reflections while the glass consists of scratch-resistant aluminium silicate. Hopefully, there’s some sort of dust- and fingerprint-resistance built-in too…
The Hyperscreen is powered by artificial intelligence and software that can learn and adapt to the user and make personalised suggestions for how the infotainment should be used.
Thanks to what Mercedes calls the ‘zero layer’ the user doesn’t have to scroll through submenus or give voice commands. The AI actually helps provide dynamic, aggregated content from the MBUX system and all the services contained within it. Think of a TV learning and displaying the apps you use most frequently for easier and quicker access.
This means fewer steps to get to the key functions that you want to use as a driver. All of the most important and heavily used applications are always at the top level view, and you can have up to seven different profiles in the system. And your passenger isn’t left out, either. They get their own display and operating area too.

The 2nd generation of Mercedes’ MBUX interface recently appeared in the recently revamped S-Class and the German manufacturer has wasted no time in rolling out this extremely slick-looking version for the upcoming EQS.
According to Sajjad Khan, Member of the Board of Management of Mercedes-Benz AG and CTO, “the MBUX Hyperscreen continually gets to know the customer better and delivers a tailored, personalised infotainment and operating offering before the occupant even has to click or scroll anywhere.”
And, the fact that it’s also an OLED display means you’ll benefit from all of the TV technology’s plus points, including inky blacks, excellent contrast and awesome viewing angles.
All we need now is news on the sound system that Mercedes plans to partner with the EQS and the Hyperscreen. If it’s anything like the Burmester High-End 3D Surround Soundsystem in the previous generation S-Class, this could turn out to be a sensational in-car set-up.

CES 2021: what to expect from the first all-digital CES and all the news so far
When Franz Pöter looks out over his city from the 192 meter high Rotenberg, then In addition to the Stuttgart TV tower, he discovers many unused areas – roofs of apartment buildings. The managing director of the Baden-Württemberg interest group Solar Cluster sees great development potential in this for the solar generation of tenant electricity.
When Andreas Schmitt drives through Ostwestfalen-Lippe, he looks at rotors, which are also the most influential Opponents of wind power could not prevent it. Because the managing director of WestfalenWIND managed to win the broad acceptance of the local residents – with a community wind tariff for local residents. Two models of how citizens can contribute to funding. What’s behind this?
Local tenant electricity The landlord produces electricity from renewable sources locally on the house and sells it to his tenants. According to the law, this current may not exceed 90 percent of the Standard tariffs of the local energy supplier. “With tenant electricity, citizens are financially relieved of their participation in the energy transition,” says expert Pöter.

Sony promises a lot for its upcoming Bravia TVs: The high-end devices from the new XR series include organic displays with higher peak brightness and LCDs with many small light-emitting diodes in the finely dimmable Direct-LED backlight. Sony is joining LG and Samsung, who also presented high-contrast displays with mini LEDs at the CES.
Sony wants the screens apart from with them Improved hardware also helps with artificial and cognitive intelligence: The new XR processor is intended to bring a human perspective into the representation by bringing those parts of the image that people would focus on in reality into focus on the digital screen.
In order to present the picture as the viewer would perceive it in reality, the image is divided into small zones and the focus point is determined using databases.

Similar processes are already being used for the optimization of moving images, Sony now wants to add factors of human perception to them. For this purpose, the image is divided into many small zones in which contrast, colors and brightness are optimized depending on the focus point. In the worse case this leads to a stronger separation of foreground and background, in the better case to a high-contrast representation with more depth – tests will show the result. Sony does not reveal how many segments the image is divided into for analysis.
Mini LEDs for more contrasts The zones for image analysis have nothing to do with the zones in which the backlight of the LCD TVs can be dimmed. Unfortunately, Sony is also silent about this number. Since mini LEDs are used in the XR models, there will certainly be more than the usual Sony ones 16 zones. LG had promised zones for its new high-end TVs 2160, whether Sony wanted to use more or less dimming zones the manufacturer does not disclose.
With mini-LEDs in the finely segmented backlight, the brightness of which can be specifically changed, very bright spots can be achieved next to very dark ones in the picture.

There will be three LCD TV series with mini LEDs for full array local dimming (FALD): Z9J, X 95 J and X 90 J. All use the so-called XR contrast boost to improve the peak brightness for HDR playback: The 8K top model Z9J has the highest level 15, it is written with 75 and 85 inches Diagonal be available. The X 95 J with 10 he boost for the FALD backlight comes in 65, 75 and 85 inches , the X 90 J with 5 boost is in 50, 55, 65 and 75 Customs offered. The exact information on contrast, luminance and other technical features will not be announced by Sony until later.
Sony wants the display in a bright environment also improve with a new anti-reflective coating. In addition, the viewing angles of the XR-LCD TVs are said to have been improved, so colors and contrasts remain more constant when viewed from the side.
Higher Peak brightness for OLED TVs OLED TVs have no problems with large viewing angles anyway. With his new OLED models A 85 J and A 80 J Sony has also improved the luminance. For higher peak brightness, all four subpixels should now light up on particularly bright details – explosions, candle flickering in dark vaults, etc., i.e. RGB and white. The manufacturer has laminated an additional aluminum foil to the display back so that the organic layer does not heat up due to the higher current load. It should dissipate the heat better and thus also prevent the possible burn-in of contents.
The colors also benefit from the higher basic brightness, people perceive them as stronger. The contrast of the OLEDs is impressively high thanks to their rich black value. The supposed contrast boost in OLED TVs is therefore actually a luminance boost, while in LCD TVs it is mainly achieved via the reduced black levels of local dimming.
Sony’s model names are not very catchy: The overview only shows the brand new models with an XR processor .

In addition to the devices from the XR series, this year Sony is offering LCD TVs with the 2020 known X1 processor; these are the models from the series X 85 J and X 81 J. There are also LCD TVs with the Android operating system, but only full HD resolution from the W series 800. All other Sony TVs show 4K resolution with 3840 × 2160 pixels or 8K with 7680 × 4320 Pixels in the Z9J.
XR sound and picture In terms of sound, Sony OLED TVs differ from LCDs: With the former, the sound comes directly from the screen surface. Acoustic Surface Audio is what Sony calls the process that LG intends to use for its OLED TVs in the future. At Sony you can already find the acoustic screen surfaces in the previous year’s models. They use small actuators that cause the screen surface to vibrate and thus project the sound directly to the viewer.
The LCD TVs from the XR series should now have additional built-in speakers using 3D surround 5.1. Produce 2-channel sound. In addition to various speakers, the 8K TV Z9J uses small actuators on the display frame.
The XR TVs support Dolby Atmos and Dolby Vision. They master the Netflix calibrated mode and deliver remastered images with immersive DTS sound with IMAX Enhanced. They are also prepared for automatic calibration with Calman and, according to Sony, provide image settings in the user image preset such as the Filmmaker mode offered by many other TV manufacturers.
The signal inputs should support HDMI 2.1, i.e. 4K / 120 Hz or 8K / 60 Hz including VRR and ALLM as well as eARC. Sony could not say whether this is the case right from the start or whether it will be submitted later via update. It was said that the HDMI specification was being finalized. The same applies to the current Sony TVs.
Design and equipment The design of the Sony has revised the devices slightly, the feet of the massive but slim TVs are now attached to the side. If there is not enough space in the living room, you can move your feet further inwards. If the soundbar is to be placed under the screen, Sony supplies higher feet on stilts.
The so-called Bravia Core, an app from the Google Store for Android TVs, is new. It is available only for the 2021 he TVs and offers depending on the model, different lots of free movies from Sony Picture Universe. For these, Sony promises the best picture quality thanks to higher bit rates. Films from the IMAX library are also offered, with further platforms to be added later. You can read more about this in “Bravia Core”: Own video streaming service for Sony TVs with up to 80 MBit / s
Sony has also added a new 4U tab to its Android TVs. The series and programs preferred by the respective viewer are displayed in the bar and suggestions for suitable content are shown. (uk)
(Pocket-lint) – Lenovo’s Legion brand is a regular on the PC gaming front, so it’s perhaps no surprise that the company set forth under these auspices with its dedicated gaming phone.
It’s a segment of the market that’s seen plenty of activity in recent years, with Asus using its ROG brand to the same end, and Razer, Black Shark and Red Magic all attempting the same thing.
But can the Lenovo Legion dominate the gaming battleground?
Designed for gaming
Dimensions: 169.2 x 78.5 x 10mm / Weight: 239g
In-screen fingerprint scanner
Pop-up side camera
Stereo speakers
Rear RGB logo
There’s nothing subtle about the Legion Phone. Lettered with the words “stylish outside, savage inside” the complex finish to the exterior of the phone is designed to catch the eye. It shimmers when the light catches it, centred around a central LED decoration, much in the same way as a gaming PC flaunts its wares with RGB lighting.
Pocket-lint
The Legion branding can be set to illuminate and that rear logo can be set to pulse when gaming, as a notification or when charging. Thankfully, you get full control, so you can turn off the red flashing when charging at night.
The Legion is a big phone, with a flat display and healthy bezels, giving you somewhere to grip without obscuring the display and risking accidental touches, while the front-facing camera is a pop-up unit on the landscape side of the phone. Yes, to save you from notches or punch-holes – and to ensure face time in-game – the camera has moved completely.
There’s some texture to rear sections of the phone to provide a modicum of grip, while the cameras, again, sit in the centre of the rear rather than at the top. That means you’re not putting your fingers all over them when gaming.
From a design point of view, therefore, this phone was built to serve people who spend most of their time playing games in landscape orientation.
Pocket-lint
Many of these decisions serve that market in a way that other phones cannot: there’s no camera bump to get in the way; the wide speakers at either end of the display are hard to obscure with a hand; and there’s even a charging port on the side so you can charge and play at the same time.
And much about this we love. We spend several hours of every day gaming, so many of these things appeal directly to us. The Legion Phone feels clean to hold and play, there’s grip, the sound quality and volume is excellent. Normal phones compromise on gaming, but this device does not.
But there’s a cost to this gaming-specific design and that’s in the day-to-day experience. The other 7 or 8 hours of the day when you’re not head-down in the latest shooter, you have to live with compromises that have been made to support gaming.
Those rear cameras that are out of the way when playing are covered by your hands the rest of the time. Open the camera to take a shot and invariably you’ll have a hand in the way. The same applies to the pop-out front camera – if you’re gripping the phone and want to take a selfie, it opens into your fingers or hand.
Pocket-lint
There’s also no denying that this is a hefty phone at 236g and pretty chunky by design too. It’s bigger and heavier than the Samsung Galaxy S20 Ultra – but the Samsung phone has a larger display. Again, some of the Legion’s additional bodywork can be a bit of a drawback during daily use, even if it will be acceptable to seasoned gamers.
Performance was put at the fore of the Legion Phone experience and that explains many of the decisions behind this phone. But while there have been moves made to accommodate higher demands, it doesn’t hang together quite as well as you might think.
At the heart of this phone is the Qualcomm Snapdragon 856 Plus, 5G enabled, with 16GB RAM and 512GB storage. It’s a monster loadout and given how much phone you’re getting, it’s good value for money compared to a lot of the rest of the market.
Pocket-lint
And we can’t fault much of the performance, although we’re not convinced by the heat dissipation and cooling system. Lenovo has talked this up a lot, but you can feel the heat from the Snapdragon 865 under your fingertips towards the centre of the phone. Having come from reviewing the Sony Xperia 5 II and the Samsung Galaxy S20 FE, both on Snapdragon 865 and both subjected to similar long periods of gameplay, the Legion Phone feels noticeably hotter under load.
That makes us question how much is really effective here and how much is just part of the marketing package to push the gaming angle. Certainly, the in-game experience isn’t hugely different from a performance point of view when put alongside rival flagship devices.
Lenovo does have more accessories for the Legion phone, including a cooling unit, but do you really want to add more weight? At the same time, that sense of heating might just be down to the fact that your fingertips are always resting on the hottest part of the phone.
Pocket-lint
The huge 5000mAh battery capacity is appreciated too. It’s split into two cells, the sell here being that you can charge super-fast – at 90W using the two USB inputs at the same time. There’s a charger in the box that will give you two USB connections too, so you don’t need two separate chargers (although that also works). When connected you’ll get one or two charging logos appear depending on how you’ve hooked it up and we have to say the charger on the side is convenient for charging while playing games or watching movies.
But the battery life isn’t hugely strong. It’s driving a big display, it’s driving up to 144Hz refresh rate too, there’s big volume and brightness, so there’s plenty to drain the battery. It’s not hugely different to the S20 Ultra in that sense (also a 5000mAh cell), but we’ve had smaller devices offer better overall endurance.
Pocket-lint
Step out of gaming and yes, it will get you through the day easily enough, but this is still a big phone and it can suffer from big phone problems. With all that said, the Legion Phone is very much on a par with other Snapdragon 865 devices – it’s fast and fluid, with very little sign of any slowdown.
Display
6.65-inch AMOLED, 2340 x 1080 resolution
144Hz refresh rate, 240ms response
Lenovo’s big play with the display is offering a 144Hz refresh rate – the same as you’ll find on many gaming PCs. Smartphones have been pushing faster refresh rates – 90Hz, 120Hz – but 144Hz is less common. Is it a big difference? Not really, but it’s there for bragging rights.
What you also need to consider is the games you’re playing, as not all support those higher frame rates. Some, like Real Racing 3, will run at 144Hz – and looks glorious – but PUBG Mobile is 40Hz, while Call of Duty Mobile is 60Hz (even though it’s available at higher frame rates on other devices).
Pocket-lint
What’s more encouraging is that you can check the refresh rate you’re getting thanks to Lenovo’s software and make sure that when you make changes to the game’s settings, you’re actually getting that performance.
Step aside from that and the 1080p resolution isn’t a surprise given that frame rate is the target rather than absolution resolution, not that Full HD+ on a 6.5-inch display is bad per se. The display itself is bright and vibrant – everything you expect from an AMOLED panel – and that plays through into other content too, like watching movies.
Pocket-lint
Overall, it’s hard to fault the display’s performance. Although there is one quirk: the display settings page was completely blank. It’s not the end of the world as you can adjust the brightness from the quick settings and you can adjust the frame rate within the Legion Realm settings – but it’s one of a number of cracks in Lenovo’s software that shows it’s not on a par with the experience offered by, say, Samsung or OnePlus.
Cameras
Dual rear camera:
Main: 64-megapixel, f/1.9 aperture
Wide: 16MP, f/2.2
20MP front camera, f/2.2
There are two cameras on the rear of the Legion Phone, a 64-megapixel main camera and a 16-megapixel ultra-wide camera. It’s nice that Lenovo has spared us the trash lenses that are so common – there’s not a depth sensor, monochrome sensor or macro camera in sight (although there is a macro mode on the main camera that works better than any dedicated macro lens we’ve seen elsewhere.)
That gives a couple of sensible cameras, the main 64-megapixel pixel combining to give 16-megapixel results. It’s actually a capable camera, able to give some great shots, but it favours good lighting, unable to lift the images as you might get from something like the Google Pixel when the light drops.

That said, there is a night mode that enables longer exposures and it works well enough. Photography isn’t this phone’s primary focus, but you don’t have to feel left out, because in most cases you’ll get a decent photo.
There’s an AI mode that will add HDR contrast and boost colours to give more pleasing shots, and the portrait mode works pretty well too.
There’s one slight fiddle, which is the zoom button. It jumps from 1x to 2x (entirely digital), then back to 1x and then to 0.6x (the ultra-wide angle) on repeated presses. How anyone thought this was a good user experience escapes us. We’d much prefer a 0.6x button all the time to access that lens. You can of course pinch to move through the entire range from 0.6x out to 8x digital zoom.
The front camera can be a bit of a fiddle when it comes to selfies because it needs to deploy pushes you toward landscape orientation – so portrait selfie fans might find it’s just a little odd on the side of the phone. There’s some beauty treatment that’s on by default and needs turning off as it strips out contrast, resulting in lacklustre images. It’s also worth finding the camera’s watermark feature and turning it off unless you’re really keen on pushing the fact you’re using the Legion Phone Duel.
1/6Pocket-lint
We also have doubts about the long-term reliability of the front camera. Throughout the time we’ve been using the phone, we’ve found dust getting in and around that camera is a common thing. We’ve also had the camera fail on one occasion, opening and trying to take a picture, but then making a few griding noises and crashing the camera without saving the image.
Software for gaming and life
Android 10 with ZUI
Legion Realm
The Legion Phone Duel runs Google Android 10, at the time of writing, but is skinned with Lenovo’s ZUI. That’s something we see less often in the US and Europe where Lenovo phones are now rare – and Motorola’s phones (the company also owned by Lenovo) shipping with a close-to-stock Android offering.
Much of what you get in ZUI is themed to suit the Legion Phone. There’s the choice of an aggressive gaming theme or Android theme that you’re presented with on startup – but the Android theme, in our opinion, doesn’t ever get close enough to a stock experience. There’s some fun animated wallpapers, some meaty sound effects to match the flashing lights on the rear, to round out the sense that this device is something special.
The software is a little hit and miss, with some oddities. For example, most of the time the phone seems to wake with the lockscreen in landscape, even when you’re holding it in portrait. There’s very little home screen control either – you can’t stop new app icons being added and creating new pages as a result, and we’ve had Google Discover appear and disappear from the slot to the left of the home page as if it’s got a mind of its own.
Pocket-lint
We mentioned the blank display settings page previously and if it wasn’t for duplication of settings in the Legion Realm app – or the option to change some settings via the quick settings panel – then you’d be stuck.
You also have to be really careful to accept permissions you’re asked for – because much of the Legion Realm experience, like the swipe-down in-game control panel, will just vanish if you don’t grant permission the first time you encounter it (seriously, we spent several weeks wondering why it wasn’t there until we reset the phone and tried again).
There aren’t many additions and very little duplication of apps, with the mainstay of the additions here to add to the gaming options. The aforementioned swipe-down panel gives you access to features like power boost, brightness controls, screenshots and recording, as well as stats at a glance – like the frame rate and temperature, with a swipe down from the top of the screen.
Pocket-lint
Thanks to these details, you can see what frame rate you’re actually getting compared to what you expect – and you can see how much the phone is warming up. It’s interesting to note that many games vary the refresh rate between lobby and in the game itself.
The Legion Realm app automatically adds games and runs when you start those games, allowing you to define some parameters – you can disable auto-brightness, for example, you can block calls and notifications and other options for games.
The good thing that Legion Realm does is provide tighter control of gesture navigation, needing a double swipe upwards from the bottom to exit a game. That’s great, because it avoids the accidental swipes that can sometimes see you leave a game on other phones.
Unfortunately, Legion Realm is really guessing when it comes to adding apps – like Google Lens or the Alexa app appearing – and think they are games. When Realm mis-identifies a game, it means you then need to double swipe to exit something like Alexa. You can manually remove those apps, but we found they creep back in again, so it seems an ongoing problem.
One of the abilities you have is to deploy the front camera while you’re gaming and have your face in the game. You can blur out the background, apply masks, hats and other fun stuff. It’s pitched as a streamer mode, but it doesn’t actually record. You can access the built-in screen recorder, however, with a simultaneous press of standby and volume up if you want to record it, as below.
There are various other in-game options, like back record, which will let you save recent clips, so you can save your memorable moments, as well as the Y Triggers on the top of the phone. These are pressure sensitive areas that you can use to launch Legion Realm, like a shortcut to the games, and can also be mapped to locations on the screen.
Like shoulder buttons on console controllers, the Y Triggers could be used as main controls, perhaps for acceleration and brake, to keep your fingers off the display or for other controls. Of course, you’ll have to adapt to using them which is our biggest barrier – you have to overcome muscle memory for those games you’ve already put a lot of time into, so you might never use them.
Verdict
The Lenovo Legion Duel is very good at what it sets out to do. The combination of a big display, specific gaming features and amazing sound quality make for a phone that’s excellent at gaming.
There are some quirks – it seems to get hotter than it’s rivals – and there are some software oddities around the gaming feature. But on the whole it’s a great experience when playing.
Where the phone really struggles is in the everyday job of being just a phone. It’s bulky, it has a preference for landscape orientation use, and we’re not convinced the pop-up camera will be totally reliable – which is going to be a downside for those wanting a phone to last them the next couple of years of daily use.
Ultimately, however, the Legion Duel offers a lot for your money. There are downsides, but there are decisions to be made: if you spend most of your time gaming, there’s a lot here for you; if you’re a more casual gamer then there are lighter phones with more software refinement and just as much power.
Kohler has revealed a new smart bath that lets you use an app, or your voice, to fill up the water. That by itself seems pretty handy to me, but depending on which model you buy, you can elevate your bathing experience by changing the color of lights around the tub or even adding some fog.
You’ll also be able to establish preset routines to turn on features in a certain order so you can set your bath exactly the way you want it. For example, you can have the tub fill itself up to a specified level and a certain temperature, and once that’s done, add some fog or turn on some aromatherapy, all with a voice command to Amazon’s Alexa or Google Assistant.
Take look at the Stillness Bath for yourself in this footage provided by Kohler. I gotta say, it seems like a really relaxing tub.
If you want this luxurious bath experience in your own home, though, it won’t come cheap. Just to control the temperature and depth of the water, you’re looking at a model with an estimated price of $8,698. If you want the “Experience Tower” that lets you activate fog and aromatherapy, that’ll cost around $10,998. Both of those models will be available in July. The version that also has floor grates for overflow and the lights has an estimated price of $15,998, and it will be available in October.
While the Stillness Bath seems neat, I have to say that it isn’t quite as awe-inspiring as Kohler’s Numi 2.0 Intelligent Toilet, which has surround sound speakers, ambient lighting, and Alexa voice controls. It earned The Verge’s “Most CES” award for CES 2019. However, it appears you still can’t buy the toilet just yet — though you can sign up to be notified when it’s available on Kohler’s website.
In the run-up to the CES, Panasonic gave a preview of its upcoming OLED TV top device JZW 2004, which has screen diagonals of 55 and 65 inches to not yet mentioned prices should come on the market. The final specifications for the device will not be published until March, but the manufacturer has already presented some highlights.
Above all, this includes the new “HCX Pro AI” processor, which is supposed to recognize whether the current content is a film, a sports broadcast, a music video, a news program or a game. On the basis of this scene-by-scene analysis, according to Panasonic, the processor is then able to independently select the most suitable picture and sound settings.
According to the manufacturer, the AI was developed with more than a million Reference excerpts fed with the various contents.
Panasonic demonstrated in the video conference that the “Master HDR OLED Professional Edition “panel sets standards in the market in terms of brightness and color fidelity. c’t will of course check this on the living object.
Finally HDMI 2.1 on board The JZW 2004 will also be Panasonic’s first television with an HDMI 2.1 port. The device can accept 4K content with up to 120 Hertz and increased contrast range (High Dynamic Range, HDR). Additional HDMI 2.1 functions support a variable frame rate (VRR) and automatic selection of the mode with the lowest latency (ALLM) for games. Speaking of games: A new “Game Mode Extreme” is intended to significantly reduce the input lag. During a demonstration with the current model, the value of 14, 7 fell on 14, 4 ms.
Panasonic already supports the HDR formats HDR 10, HDR 10 +, HLG and Dolby Vision – with the current top model including ambient light sensor. At the JZW 2004 the recently presented “HDR 10 + Adaptive “are added. Finally, its speakers also radiate to the side in order to envelop the viewer more closely.
