So today I noticed a white spot (the shape kinda looks like water on a table). The funny thing is that it shows ONLY when the screen is turned off via software (fn keys) and during the change from a graphic mode to another (like booting a game).
During normal operations is perfect, even on black background, when the screen is completely turned off it doesn't show anything.
It seems really strange, can someone tell me why?
Thank you very much
