Question Samsung QN900A / losing signal

[sioux]

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

I'd try a different driver. Are you using a non-standard refresh rate, trying to bump it as high as it'll go?

Are you using the factory cable too, and not some amazon Chinese brand that looks cool and is braided?

I noticed poor cables can cause this as well.
