An LG 22MP65 monitor with an IPS matrix is ​​connected to a Mac Mini via HDMI. When waking up from sleep, the monitor screen often displays the main picture, but in color streaks and spots. Opening different windows does nothing, just turn off the monitor and turn on the touch button. What is the reason and how to cure?

Answer 1

I often have the whole picture in pink light after turning on the monitor, and I did not find how to treat it. After a couple of turns on and off the monitor, everything stabilizes, by the way, the monitor is also LG.

Answer 2

Found out that the problem is in the monitor. I took a screenshot at this moment of divorce - the picture is clean. So it's at the output level.
