I don't know if this is a common problem or what. but my monitor after prolonged usage has started to eep (make a whistling / screeching sound) the only way i can seem to fix it is leave it turned off for half an hour or so then return to it. Now its a fairly new monitor so i can't justify buying a new one right now so does anyone know why this is happening or even a solution. i'm guessing its down to over-heating, but its not THAT new, so why has it started doing it now? btw, its a Hansol 710p 17" running @ 1280x1024.
