vibrating screen on MacMini 2018
Hi.....I'm using a Mac mini with Parallel on it as I also need Windows to run MT4 forex trading. Lately the attached monitor - LG 27UL850 W - started to vibrate , flickering on the screen while I was working on it.
it was stopped vibrating when I switched out the monitor, however, later on, it came back when the IOS system suddenly woke up on his own and asked for my screen password. This time it did not help when I switched out the monitor, I had to turn off the Mac mini as well. After restarting there was no screen vibration.
Is it a problem of the monitor (which is pretty new), I purchased a month ago or a problem of Parallel or MacOs Monterey or hardware problem?
Can I get any guidance how I can figure out the root of the vibration problem?
