When I stand up and look down to the screen, it is noticeably brighter on the top. However, when I look up from below the screen, it is darker on the bottom. Just bought this a week ago and there is no issues with it besides this brightness and darkness issue. My current setup is where my eyes are lined up just over the middle of screen so it isn't noticeable, but I don't know if I have something that's faulty or It's nothing but normal. Also, I own 2 Acer r240hy bidx's and they are the same brightness throughout the hole screen. Please tell me what you think.
