Hi, I own my Surface Pro 2 for about half a year and was very pleased with it in the beginning. But then I noticed a problem with the Screen. I thought it was the graphic driver or something but updating windows and the actual intel drivers did not help. I set my Surface to factory settings and the problem was gone! UNTIL I started to Update Windows again. I contacted Microsoft and they sent me 2 replacement devices, which all had the same issue after updating. I also followed the support instruction and tried a new Microsoft account but nothing helped. Here are some pictures i took with my camera (since the defect doesn't appear on screenshots). It also doesn't appears on external displays connected to the miniDisplay port. It's in every Browser as well as on video files or even the background or screensaver. ( I played the new Batman vs. Superman Trailer in 1080p. Only the dark/grey areas get highly pixelated) http://imgur.com/a/KV5qp#2 Here's also a video: So Microsoft Support said that the only thing they could do was sending me another surface pro 2, I decided to return the Surface, as in Germany it is possible to return goods that failed repair 2 times in a row. I bought the Surface on an eBay shop, so Microsoft said I have to return it there. But the eBay seller refuses to take it back. I'm kind of angry and really confused, because it seems that I'm the only one with that problem, but I'm not the only one who noticed it on my Surface and I tried almost everything. What do you guys think about that? Thank you in advance!
