For several years, the monitor market has been seeing an increasing interest in high refresh rate models. Initially, we were happy with 60 Hz, later matrices appeared successively 100 Hz, 120 Hz, 144 Hz, 165 Hz or 240 Hz. Earlier this year, several manufacturers unveiled monitor prototypes with an even higher refresh rate – 360 Hz, which were combined with the new NVIDIA G-SYNC module . During the presentation of GeForce RTX graphics cards 3000 from the Ampere family, NVIDIA also discussed one of the new functionalities that has been built into the aforementioned G-SYNC module. I’m talking about the Reflex technique, whose main task is to reduce the delay in the most dynamic esports games or Battle Royale titles. Courtesy of NVIDIA, as the first editorial office in Poland, we had the opportunity to see this novelty on the example of the Dell Alienware monitor 25.

Delay, i.e. input lag is one of the key features of monitors. In the case of models for players, it is important that the delay is as low as possible. Nobody would like a situation where playing multiplayer games becomes a torment, when there is a too late reaction on the screen in the context of what action in the game we perform in a given second. Input lag is defined as the delay of the displayed image in relation to the time of the control signal. You could say that this is the time between sending the image to the TV and displaying it. The smaller the indicator given in milliseconds (ms), the better. Although many monitors already offer a really low latency, NVIDIA has introduced a proprietary solution, thanks to which we can enjoy even more reduced input lag in supported games. This technique has been dubbed Reflex and has been announced with GeForce RTX graphics cards 3000.

NVIDIA Reflex is one of the new techniques introduced with the new generation of GeForce RTX graphics cards 3000. Thanks to it, the supported games are to have the lowest possible delay. NVIDIA Reflex works with GeForce 900 and newer graphics cards.

Fortunately, in the case of the NVIDIA Reflex technique, we are not limited to choosing only the latest Ampere graphics card. The manufacturer has confirmed compatibility with GeForce GTX and RTX cards based on Maxwell, Pascal, Turing and Ampere architectures. mid-range, such as GeForce GTX 1660 Ti, as well as on much more powerful GeForce RTX cards 2080 Ti and even faster GPUs.On the next page we will discuss the NVIDIA Reflex technique in more detail – we hope that this solution will become more common in the coming months, although it cannot be denied that at this point only a very small group of monitors allows you to accurately measure latency due to the hardware of them plementation in the NVDIA G-SYNC module. In addition, it will be up to the game developers whether they also use the Reflex SDK in their titles. The coming months will show whether there is any interest in this technology.

The NVIDIA Reflex Latency Analyzer tool for measuring latency is currently compatible with several monitors with a refresh rate of 360 Hz. devices: Dell Alienware 25, ASUS ROG Swift PG 259 QNR, Acer Predator X 25 and MSI Oculux NXG 253 R. All these devices are characterized by the use of a matrix diagonal 24, 5 “and resolution 1920 x 1080 pixels. In the future, we will certainly see even more advanced monitors with
