Hey everyone, I'm on my third LED Cinema Display (for various issues) but I've noticed all of them have DOZENS of very tiny specs of color that are only apparent on a black screen. Furthermore, they seem smaller than an actual pixel (have to be up very close) and they are only apparent at certain angles (and even sometime change color) as opposed to dead/stuck pixels. These always pass my initial dead pixel check over a full black or white screen but I find them once I get in real close. Has anyone else noticed these? Any ideas what these actually are? Thanks in advance.
