Hi all,

regularly since a week ago I see 100+ horizontal blinking all over the place.
Even if I switch the screen to an input that is not connected (black screen while still seeing the blinking lines).

Any idea? It's not GPU or cable related.
Any interference from Wireless devices?
My guess: Screen is simply defect. Luckily it's only 8 months old.

Thanks for your input!
