Problem with DisplayPort

[Oscaar92]

Hello, i have some problems with my graphiccard or monitor. HDMI works just as it supposed to. But DP is a bit tricky. When i start Call of Duty, or any game the screen will be black and search for a connection, won't find the source and it will say "No signal". If i press the windows-button on the keyboard and go back into the game it will show the game. I have changed DP-cable and tested my old monitor and haveing the same issue with both monitors with DisplayPort and not with HDMI.

My new monitor is a ACER Predator XB323UGP

So, i think it's the graphiccard because i've testet 2 monitors and 2 different cables and having the same problem with all of them. Is it the graphiccard?

Kind regards, Oscar R

probably, what model exactly do you have?
still under warranty?

[Oscaar92]

The full modellname is: OMEN 30L Desktop PC GT13-1000a (207P6AV)

Yes, still under warranty. But can i somehow secure if it's the monitors, cables or graphiccard?

And it's the same issue with all 3 Displayport-inputs.

OMEN 30L Desktop PC GT13-1000a (207P6AV)

this does not appear to be an accurate model

"So, i think it's the graphiccard because i've testet 2 monitors and 2 different cables and having the same problem with all of them. Is it the graphiccard?"
"And it's the same issue with all 3 Displayport-inputs."

this seems to be more of a problem with the computer

See if there are updates, for the graphics card, if that does not solve anything, I strongly advise you to contact the after sales service

if you test the monitor  with another computer, and it works, it is ok ..

[Oscaar92]

We try with this then: HP Omen 30L GT13-1879no

I will somehow get the hands of another computer to test it with. But i think like you, it's most likley the computer. The drivers is up to date with the latest. Uninstalled and reinstalled without any progress. 

I got the modelname as i registered the computer at HP.com

Hello, i've done alot of things. The "solution" was to creat a new admin-account in windows. Simole as that, now it's time to reinstall my computer and not update to win 11 for a while.
