I have a generic 17" VGA monitor that i got (assumingly brand new) from a guy about 3 or 4 years ago. Lately, it would become extremely bright, as if the brightness knob were turned up all the way, and then some. i tried to adjust the display settings on the monitor, and also on my video card (GeForce 2) but nothing worked. after a while (like a week maybe) my monitor just returned to normal. this happened about a month ago, and now it has just happened again. can anyone help me?
