On my screen, where there is solid white, black, or color shading, a light teal color covers everything else. The effect fluctuates on and off, but the severity increases if I attempt to do something like play a game or watch a video. It might be a problem with my graphics card, seeing how when I got my laptop, it was refurbished, not new. But being who I am, I don't know about all of the technicalities of computers. When I attempt to run a diagnostics check, the computer tells me that there is nothing wrong. I attached one picture of the shading problem that occurred while I was playing Team Fortress 2. Where there is solid white, the same teal color appears, only it is in a solid block, covering all of the white.
