I keep getting screen glitches and have no idea why. Whenever I surf the internet on my laptop and play ps5 these glitches would randomly appear! It could be a period of maybe 10 minutes where they constantly appear then I can play for 2 hours and then nothing happens then they suddenly appear again! Please help, this monitor was very expensive, and I only bought it in February. It has not been dropped, or water damaged, just happened randomly when I turned on my ps5 one day! Look in the screen shot attached and you will see what I see every so often. I have changed the HDMI cables, I have changed the ports, it still happens on both Pc and PS5. I have changed the power cables. Still happens. I am at my wits end. Is this a software or hardware problem? The seller won't change it for me as I have thrown away the box! Is this fixable if it is a hardware problem? Please advise.
