Monitor loses signal

[Moriaan1990]

hey,

bought a used 32inch ultrawide monitor

conected tho intel 4000 onboard grafik whit good hdmi cable.

monitpor uses signal every now and then...signal comes back after like 2 seconds.

anybody knows why?

I think that the Intel 4000 does not support 32inch resolution with HDMI.

You should try with DisplayPort cable or upgrade the VGA card.

Hello, you can try update VGA driver, update BIOS/UEFI firmware. It is desktop or notebook? Did you tried it with another computer/device? It can be problem with monitor.
