Hello, I'm using the Samsung QN900A on my PC, with the RTX 4090, HDMI 2.1 cable

Sometimes ( often ) when I leave a game, there is no signal and I need to restart the PC

And during the game, the display goes black for 2 seconds, sometime

I have Game Mode ON

nVidia settings

Output color depth - 10 bpc

Output color format - RGB

Output dynamic range - Full

Could anyone help me, please ?

Thank you
 
Had similar simptoms (intermittent black screen) with sub-par hdmi cable (it was certified) so my first suggestion would be to change to another certified hdmi cable.

Another possibility could be bad GPU (also had that happen to me when GPU was not making full contact with water block), but there should be other simptoms (looping sound, driver recovery notification or something along those lines).
 
Looping sound comes from.....??
I'll try another HDMI 2.1 cable
Thank you
