I've noticed these marks on my screen, like splotches, that aren't scratches or something on the surface of the screen. They are much more noticeable when looking at something dark. At first it was relatively small, but it's gotten a little bigger recently. I'd take a picture, but they don't appear in a screenshot, and you can't really see them in a photograph of the screen, so it's hardly worth it.
Does anyone else have the? Or know what it could be?
