Question I don't know if this is a GPU issue.

[Apatay]

Hello. I recently built a computer and now I'm having a small problem.

I set my screen to turn off after a minute (it doesn't matter how long) and it turns off. Then it says display port NO SIGNAL for a few seconds then goes back to DISPLAY port and stays on the entire time.

If I connect the DP cable to the motherboard. This doesn't happen. I'm very confused.

CPU: 7800x3d,
MOBO: Asus B650 WIFI PLUS
GPU: ASUS DUAL RTX 4070 SUPER EVO OC EDITION

Any ideas or solutions?

All yes. However, I was using the onboard graphics for a few days. Then I ddu’d it.

reset BIOS by jumper
install the onboard graphics driver as well

check/repair windows with dism commands:

BIOS was updated after the new GPU installation anyways. So it must be reset already.

AMD onboard driver is already installed.

scan result is this

Also did the repair.

no, the bios not necessarily resets itself after a bios update, that´s why manufacturers recommend resetting the bios after a bios update

so might be a windows image problem

I don't feel like resetting the bios will fix it but gonna do it. What's the next step?

if windows repair doesn´t lead to success,
maybe check with a different video cable and port and different type of connector like dp to hdmi or vise versa

edit:
any 3rd party apps like ASUS AI Suite or similar installed? uninstall

It has 3 dp connectors. They're all the same. The backlight only turns off if it is connected to the motherboard directly.

Something is wrong but I couldn't figure out what.
