Recently got this LED Display on eBay and when it arrived I quickly noticed it had these vertical lines running through it. They are pretty much on the entire display. They are almost invisible on a white screen but when it is dark they become very noticeable. I cannot find pretty much anything about them and the seller said that they didn't experience them before they shipped it out. It happens on both a Mac Pro 5,1 and a PC using an adapter, as well as a 2015 MacBook Pro using Thunderbolt. Anyone know the problem or how to fix it? Also, maybe this could help, the display does not seem to wakeup when the computer falls asleep. Could be completely unrelated though.
