I plugged the screen after 2 days of non use and it still does this, but it was after unplugging it, opening it and plugging/unplugging all the flat cables inside, did nothing but I believe the issue is a malfunctioning cable(s) inside the screen itself, will try it again. My graphic card is working just fine, as I have 2 screens and the Asus is the only faulty one. Also can't replace it, the warranty is over sadly.
