I have a burn mark on my screen, and it seems to get bigger and bigger. I don't know why it's there. I know about ghosting, but my screen saver is usually running if my computer is idle. The only thing I can think of, is how I run it all the time. It's a laptop, and I use it for everything: gaming, programming etc. It stays pretty hot because it's on about 6-8 hours a day.
