QN90B 50” - Game Mode not working

[Jeepster1]

Ref:  Latest Samsung 50 inch QN90B 2022 model TV (QE50QN90BATXXU) with 144Hz VRR 4K being used as an external display via a HDMI 2.1 connection link from an AORUS 17X-YD PC gaming laptop with RTX 3080 internal graphics card inside.

The external Samsung 50” QN90B (2022) TV reports and shows the correct 4K resolution at 144Hz when connected to the HDMI 2.1 socket on the RTX 3080 graphics card (laptop).

NVIDIA Control panel on thenPC laptop reports and shows the correct 4K resolution along with the correctly set 144Hz…

However the issue is when putting the 50” QN90B TV setting into Game Mode ‘on’ for using VRR, because suddenly the source signal from the Laptop’s RTX 3080 is lost all together and the TV thinks that the computer is ‘off’ though it is not. Turning off Game Mode on the 50” QN90B TV results in the picture coming back and being received once again from the PC laptop at 4K 144Hz, but it is without any VRR (or G-sync).

I had a feeling the TV may have issues being so new from production.

Any solution, or is it a return job?

Yeah i've found on my TV (QN95B) the fastest games modes that work are 4k (3840x2160) at 60 hz, 2k (2560x1440) 120 hz, at 1k (1920 x 1080) 144hz, it cannot reliably run 144hz or 120hz at 4k nor 144 hz at 2k, so incorrect advertising for sure.   Exceeding these limits leads to "black outs" in the screen.  I have changed the cable to a premium 8k capable, but no improvement in the video issues.  So I don't recommend Samsung for these reasons.
