What does this mean for standard TVs that people us for gaming. LG/Sony/Samsung OLEDs tend to be able to do 4k@120, having native 120hz panels. Maybe this only covers "monitors" getting freesymc certified.
Rtings says that the LG (B2 at least) TV's support VRR via several standards: HDMI 2.1 , FreeSync, and GSYNC. I have a console hooked up, but no GPU good enough in a PC.
its freesync/gsync over hdmi 2.1 standard. Nivida does not have a Gsync over HDMI in the standard hdmi connection. There is no non 2.1 hdmi monitor/tv that will accept VRR over HDMI on Nvidia. Only AMD had Freesync over HDMI (on very low end budget monitors)
Gsync Compatible is basically gsync over the display port standard. Gsync Ultimate is over the FPGA which uses display port as a medium.
idk about technical documents perse, but heres a news article when AMD introduced VRR over hdmi ways back, noting how vrr on hdmi wasnt a thing yet, so AMD partnered with monitor makers to use a different scaler that would make it compatible with freesync.
VRR over display port would be in the Displayport 1.2a specification sheet. VRR over HDMI (officially) is under the HDMI 2.1b sheet.
