TV QN90B automatically disable game mode everytime i turn on my PC

[Rbspec]

Hello guys, how are you? 

I have a Nvidia RTX 4070 Ti, connected via HDMI 2.1 cable/ports to my 43" NeoQled QN90B, using this settings:

Game mode on, 4k, 144hz, HDR, VRR, 10 bit color, 16:9 aspect ratio.

It worked fine for some months, but suddenly, my TV started to disable Game Mode everytime my PC turn off. All the other settings stay the same, except for game mode. Seems like this setting is being reset.

How can i fix it?

I have the same problemas as you, and I am using a Mac. Every time I disconnect the HDMI cable, game mode is disabled. It's very annoying.
I think samsung is not aware of this issues, and will never hear anyone os it's own forums.

Hello, I just had the same problem as you. I have an rtx 3060 laptop, and  I found a fix. What I did was perform a clean uninstall of the Gpu driver using DDU. Then, i performed a custom clean installation of the latest nvidia driver using NVcleaninstall, and that fixed it for me. Just make sure it is a clean installation and I hope that fixes it!
