This only happens in games, but it happens in ALL games. When I'm playing games I can see the screen refresh. a near-transparent stripe stripe moves vertically up my screen at a very rapid speed every half second or so. This does not happen when I'm watching movies or when I'm on the desktop. Vsync doesn't help, as I'm running games under 60 FPS. I have a BenQ G2420HD set to 60Hz, my refresh rate in games are also manually set to 60 herts. Graphics card: ASUS GTX 570 Direct CU II with the latest drivers CPU: i5- 2500K overclocked to 4.0GHz on stock voltages, 62C under load. Stress tested with Prime95 Blend for 4 hours, no errors. Driver version 280.26 Power Supply: Corsiar TX650 RAM: G.SKILLS Ripjaw X 1600Mhz (stock freq.) Motheboard: ASUS P8P67 is this a driver problem or a monitor problem? can I fix them without replacing components? All replies are appreciated.
