I'm noticing the following behavior on my Q90T
If I enable game mode low latency, I can't do 4k 120hz HDR 10 bit on HDMI 2.1 (VRR works)
If I don't enable game mode low latency I can do full HDMI 2.1 but VRR is flickery....

Is this expected behavior? Noticing this partially with the PS5 and with my multiple PCs I connect via HDMI 2.1 (and yes I ensure each is connected to the HDMI 2.1 port to check)

For clarity when I use HDMI 2.1 and game mode

  1. VRR works
  2. 4k 120 hz mode works with 420YCbCr
  3. HDR is non functional within windows and only 8 bit streams can be chosen

when I use HDMI 2.1 and no game mode

  1. VRR functions but its strobe effect flickering
  2. 4k 120Hz mode works with 444YCbCr
  3. HDR is functional with 10 bit strreams

I know you checked the port, but what spec cable are you using as well?
