Try firestick first. If that still shows it is the monitor.So this morning i turned the monitor on and the same thing happens again i did take a screenshot of it but the artifacts not showing up in the screenshot. This dam monitor is just over 6 months old so i don't know if where i bought it from will replace it now or will i have to go through the whole process of contacting MSI and shipping it to them. I can see bit of a nightmare ahead with this
I will try my fire stick in it as a last resort and see what happens, but it only does this after the monitor has been off for a prolonged time.
Then back to supplier. If supplier not wanting to help then it's MSI
