IDK how to describe it but i'll be on the laptop doing nothing in particular and randomly the screen will slowly (in steps not all of a sudden) start to loose brightness (as if you where turning the brightness down) but the colors (at the same rate) begin to get brighter/whiter until the piont where what used to be gray is now really white, purple is like bright-pink, etc. I can only fix it by closing the laptop and re-opening it then its fine, none of the settings are changed before or after this happens. I'm not too worried about it because I can sorta fix it, but i guess whats grinding my gears is I don't have a clue whats causing it, any ideas? Oh it's a 16:9 HD LED LCD screen if that helps.
