After my screen has been black, not shut of but just on a black screensaver for a modest amount of time and I take the computer out of that mode the screen flashes light and dark and is a little bit darker overall. It eventually wears off but it is really annoying. Is that normal? My monitor hasn't done that before and it just started happening acouple of days ago.
I'm assuming this is an LCD that uses CCFL backlighting rather than LED's...in that case, I would guess that either the lamp tube itself or the voltage inverter are on their way out. How old is the display?
I can't remember how old it is exactly but I don't hink its more than 2 years old. Could this just be a sign of something "warming up"? Becuase it starts out dim and flashes until it gets gradualy brighter then it stops altogether. But that doesn't explain why it just started happening.
