Unfortunately, LCD technology is still not good enough to guarantee defect free screens which is why you cannot buy large 40" LCD screens. click here for more details.
I also have a problem with my LCD monitor. It's incredibly annnoying because it doesn't have dead pixels, a small insect has gotten itself stuck in between the protective layer and pixel layer of the screen and its died their so it won't move back out. Any ideas if I could get it out?
