My son has a Toshiba Qosmio G10 laptop which is about four years old. It has recently developed a display fault in the form of a very fine (single-pixel?) continuous vertical line that runs from top to bottom of the screen about 1/2" in from the L/H side. Against any background other than white this line is red, but against a white background it is blue.
Is this likely to be due to a corrupted driver or could it be a problem with the screen itself?
My son tells me that the graphics chipset is NVidia Geforce FX but I can't check this myself because he lives overseas.
