Hi, Recently I just noticed that there is a black smudge on my screen I thought it was a dead pixel but when I took a screenshot on the computer, the mark showed up on the picture, I'm not sure whats going on here but any help would be appreciated. I've done those screen fixes etc but non have worked. It also doesn't show up during games but that might be because I can't see it. https://imgur.com/YljD30u
