Over the years of the NVIDIA G-SYNC refresh technique, we have had three different implementations, depending on specific monitors and requirements. The most basic, G-SYNC Compatible was announced in January 2019 and any Adaptive-Sync compatible monitor can be certified. It is worth remembering that G-SYNC Compatible is the only one that does not require implementation at the hardware level. NVIDIA G-SYNC as the second type is designed for more demanding monitors and in this case we are talking about installing a special module into the monitor. The third and so far the most extensive variant is NVIDIA G-SYNC Ultimate, designed for the best monitors with a very good HDR implementation. It turns out that NVIDIA has recently quietly lowered the requirements for the G-SYNC Ultimate certification.

In December, NVIDIA decided to lower the requirements for monitors wishing to receive the G-SYNC module Ultimate. The changes apply to the maximum luminance in HDR mode.

NVIDIA G -SYNC Ultimate was introduced at the beginning of 2019 of this year (along with G-SYNC Compatible and laptops with GeForce RTX 2000) as the most advanced form of refresh technique that combines the best features of monitors and the hardware implementation of the NVIDIA G-SYNC module. The requirements included the following parameters: luminance in HDR mode at the minimum level 1000 nits, multi-zone backlighting, combination of high resolution and high refresh rate, very low latency and support for a wide range of colors. The requirements in this form were on the NVIDIA website until November. It was only now noticed, however, that this list had changed somewhat in December.

The change concerns a parameter related to luminance in HDR mode. As before it was at least 1000 nits, currently on the manufacturer’s website there is only information about support for a wide tonal range (HDR), without a specific specification of the brightness level in this mode. This means that future monitors seeking G-SYNC Ultimate certification will not need to have such a high HDR luminance level. Thus, the requirements are falling and from now on monitors with lower brightness will be able to obtain the highest certification for the G-SYNC Ultimate refresh technique.
