There is an annoying vertical (dotted) line on the left side of my Philips 349P (34-inch, 3340x1440, 60 Hz) screen which is connected via HDMI to my Mac Mini M1 (Ventura). It has been there for months actually, so I hope there is a solution to this problem.

+1 Rows of pixels in a line like that are usually caused by a damaged or faulty display panel. I would contact Philips and check to see if it is covered by the warranty.
Test a short premium certified HDMI cable.
Or if that display also has DisplayPort input, try an 8k USB-C to DisplayPort cable.
if it was me then I would test it with another computer to make sure it was not a hardware issue
It is not the display. It works fine on a different computer.
Maybe the Mini M1 struggles with this resolution? Does anyone else have this kind of screen connected?
