At CES 2019, Nvidia announced that they're expanding G-Sync support to a handful of FreeSync and Adaptive Sync compatible monitors. In order to "improve the experience for gamers," Nvidia is testing monitor compatibility on a case-by-case basis, and only enables VRR support in the drivers once the monitor has passed their validation tests. Fortunately, there's a switch in the driver control panel to enable VRR support on untested monitors, the company says "G-SYNC Compatible" monitors will support VRR on both 2000 and 1000 series GPUs. For "the most demanding gamers," Nvidia also announced a separate G-SYNC Ultimate HDR standard. Monitors that carry this branding have to pass a rigorous certification process that includes " 300 tests for image quality," and will feature "a full refresh rate range from 1 Hz to the display panel's maximum rate, plus other advantages like variable overdrive, refresh rate overclocking, ultra-low motion blur display modes and industry-leading HDR with 1,000 nits, full matrix backlight and DCI-P3 color." Support for G-SYNC Compatible monitors will begin Jan. 15 with the launch of our first 2019 Game Ready driver. Already, 12 monitors have been validated as G-SYNC Compatible (from the 400 we have tested so far). We'll continue to test monitors and update our support list. For gamers who have monitors that we have not yet tested, or that have failed validation, we’ll give you an option to manually enable VRR, too.
