Sometimes, when zoom is launched or when someone shares their screen on zoom, my computer monitor flickers, white/grey colours most affected. It doesn't happen when I share my screen.
Even when I quit the zoom app, the flickering will stay, sometimes for a few days before it eventually dies down and completely stops. The flicker will even occur if I disconnect my laptop (so that there are no inputs into the monitor).
The problem doesn't happen often but when it does it drive me nuts as it's really uncomfortable for the eyes.
I've tried replacing my monitor under warranty and I still have the same issue. The monitor is connected to a MacBook Air (M1, 2020). I've also tried:
Turning the monitor on and off
Using a different cable
Using a different laptop
Changing the setting on my Mac (colour profile, True Tone, Resolution, Refresh Rate = 60Htz)
