When room is cold e.g. 13deg is the worst i've seen it or < 19 deg at least, the signal is completely glitched up (green, pink, black/white bars/fuzzies) and delayed.
HDMI works fine, lower resolution does not help, but the moment I switched to 100hz or 60hz the problem went away.
I have noticed other glitches when watching videos sometimes.
Thinking to try a new display port cable, is there anything in particular I need to watch out for when buying them?
Cheers,
