Screen flickering

[JabraKingston]

I have an Intel Arc770a installed in an HP Z6 Workstation.

When in Windows (11) the screen keeps flickering, white lines appear randomly, and now and then it just goes black for a few seconds.

This issue also occurs in the bios and when booting.

It does not appear when watching video or playing games. But if the game is minimized it´s a lot worse.

I have installed the latest drivers as well as all OS and hardware updates including a bios update. It is connected to a Dell screen using displayport.  It is a new set-up so It hasn´t worked before.

Any ideas?

Hello JabraKingston,

We want to thank you for reporting your problem in the Intel Communities. We would be more than glad to help you solve the flickering issue. Based on the information provided, we would like to recommend you try the following:

• For testing purposes, and if it is possible, try different monitors and display cables.
• Are you using any type of adapter? It is important to mention that we always recommend using straight connections with no video adapters/dongles in between.
• Since you mentioned that the issue occurs when using DisplayPort*, you should use a different video output like HDMI.
• Would you mind sharing a picture of the flickering issue you described?

Best regards

Hello JabraKingston,

We analyzed the information you have provided us and one key detail is that the flickering can be observed even at BIOS level - as you know in BIOS there is no driver support hence we believe the issue is isolated in either the GPU itself, the cables or the Display.

We would like to reiterate our previous advice: try different monitors and display cables and use a different video output like HDMI.

Depending on the results from said tests we can say with more confidence where the issue may be coming from.

Best regards
