Acer Nitro XZ342CUP When I turn off the monitor on the on/off power button on the screen,

Hi guys

If u see attached picture, this is what happends after some usage time.

It started yesterday, the minitor is 2 years old. Its a ”Acer 34" Nitro XZ342CUP QHD 21:9 Curved 144 Hz”.

All cables seems to be attached. When I turn off the monitor on the on/off power button on the screen, and thurn it on again, the problem is gone. After some time, it comes back. Nothing i do or press fixes this except a reboot or on/off button.

My OS is Windows 11. Please advice. What is the source of the problem? I dont wanna buy a new monitor after only 2 years :/

Hi @Ghost79 It looks like an effect of electromagnetic fields, do you have speakers or appliances near or behind those walls?

It can also be an effect of bad filtering of the electric current, does the plug have a ground connection?

Is it connected directly to a wall socket or does it use an extension cord?

Thank you.
All the best.
