New Screens Certified Under the NVIDIA ‘G-sync Compatible’ Scheme
Back in January NVIDIA shocked the World by opening up support for its G-sync Variable Refresh Rate (VRR) technology from normal FreeSync/AdaptiveSync displays. This suddenly gave NVIDIA graphics card users a whole new set of possibilities when selecting a display if they wanted support for the all important VRR, helping to avoid tearing and lag associated with older Vsync off/on methods. You can use G-sync on pretty much any AdaptiveSync display, but many will have varying results and success. Only a small selection of these screens were officially tested and verified by NVIDIA under their ‘G-sync Compatible’ scheme. At the time only 12 monitors made the cut, but the list is growing and now new screens have been certified. Read on for the latest information.
The list of ‘G-sync Compatible’ screens is kept up to date on NVIDIA.com, and only those listed have been through NVIDIA’s testing and come out the other side. This testing validates that the monitor does not show blanking, pulsing, flickering, ghosting or other artifacts during VRR gaming. They also validate that the monitor can operate in VRR at any game frame rate by supporting a VRR range of at least 2.4:1 (e.g. 60Hz-144Hz), and offer the gamer a seamless experience by enabling VRR by default.

It should be noted that this list also states that none of the current G-sync Compatible screens feature variable overdrive. Two are listed with HDR support, those being the Acer XV273K and Gigabyte Aorus AD27QD. Although both are HDR400 certified with no local dimming capability.
Newly certified models
New in this list since the last update we did on 2nd May 2019 (this news piece, now updated) are:
(links to original news pieces for each included above).
The LG 27GL850 is an interesting one, as when that was announced it was listed as a normal G-sync screen. If it’s now “G-sync Compatible” then that implies that either there’s a new unannounced FreeSync version coming at some point, or the screen spec has been updated to support Adaptive-sync instead and therefore offer both FreeSync and G-sync. More clarification as we get it.
Be wary of manufacturers who list their screens as ‘G-sync Compatible’ in the specs, if they do not appear on this list. The screen can probably ‘support’ G-sync to some degree, but unless it’s on NVIDIA’s list, it isn’t officially certified. We expect manufacturers would be in violation of NVIDIA’s certification scheme if they list their screens as ‘Compatible’ without having earned the badge properly. Perhaps all those other displays should be simply referred to as having ‘G-sync support’ instead?
