QN90A 120Hz Freesync Premium Pro VRR + HDR not recognised by TV (AMD/Windows)

Tested UE50QN90A + AMD 6900XT Aorus Master. (FW 1506.0 / Radeon 21.5.2) / Windows 10 21H1

Windows + Playing Games:
(Windows Settings + Ingame HDR Toggle)
120Hz HDR 10-bit NO game mode, TV reports 3840x2160 / 120p input signal plus (HDR + UHD) OK!

With Game Mode Enabled:

Windows:
120Hz HDR 10-bit VRR on (Windows Settings), TV reports 3840x2160 / 120p input signal plus (UHD)
HDR is missing

Playing Games:
120Hz HDR 10-bit VRR on (Windows Settings + Ingame HDR Toggle), TV reports 3840x2160 Freesync Preium Pro / 120p input signal plus (UHD)
HDR is missing

There seems to be a bug where the TV isn't recognizing HDR in Game Mode and the picture is overy dim/dark & washed out. Some games like Call of Duty look so bad the TV + HDR calibration ingame cannot correct for the terrible picture quality. Some games like Doom Eternal + AMD driver color profile allow me to correct the colors to usable levels, but color ranges seem compressed / crushed. RGB output fares worse than YCBR4:4:4, where on RGB even Doom Eternal cannot be corrected to look good.

I solved the issue with Custom Resolutoin Utility (CRU). I edited the Extension Block and added the support of FreeSync Range 48-120Hz.

It is quite self-explaining but if You do not know what to do just watch this video:
How to enable Freesync on non freesync monitor or TV 

Of course, You will do this on different equipment so the data for your set will be different.

Ps.: Do not forget to export the settings before you change anything.

I have a Vega 64, which HDMI is 2.0b so it can do 4k@60hz instead of 120hz. Does it change something with your advice ?

I guess it does not change anything. Its FreeSync might be not compatible but give it a try. CRU includes a reset-all.exe which resets all HDMI EDID so after you restart the PC the display will be detected again with its original EDID settings.

Might not br compatible with CRR or VRR ? Because it work fine FreeSync Premium Pro (without HDR). Thank you for your quick reply

Then it is compatible but You won't get HDR with 10 bit with HDMI 2.0b if I am right. You have to use 8 bit.
