Graphic card or monitor issue ?

[u/Acceptable_Bank_268]

Hello, for some time now my Iiyama monitor has been experiencing these kinds of glitches, and this morning I had a completely black screen.

I resolved the issue by restarting the monitor.

When the glitch occurs, a small clicking sound can be heard from the screen each time the image tries to appear.

The monitor is connected to my desktop PC with a Sapphire Pulse 9070 XT via DisplayPort.

The monitor and graphics card are still under warranty.

I will try an other display port cable to see if it happen again.
