Hmm you may be on to something here. I mean my monitor is not that high end. 60-65 hz and a 5ms delay make me think that the monitor isn't keeping up, not the video card. Thx for the ideea, now i have to look for a new monitor too edit: Checked and it does the line thing just wen it changes resolution adding the slow speed of the monitor i tend to go in favor of the monitor as being the problem. Well not a problem just that you see what your not supposed to, or something like that, not sure tho.
