ok... i have an odd problem with my display that happened briefly a while ago, but stopped. Now it appears as if it's back.... what is it: like a row of dead pixels... except i can see some color information from it..... and it's a single-pixel row. the problem has occurred before, but it's gone away mysteriously..... i tried taking a screenshot, but the line does' show, so i know it has to do with the display. i have a 17 inch studio display. i don't think it's all dead pixels because they are in a perfect row spanning the width of the screen... have any of you also had this problem before? got any suggestions?
