[QUOTE="RobbertV, post: 802650, member: 86586"] Hi! Thanks for answering so quick :) I'll try to explain it different: I think, after what you said, that my whole mac hacks for a fraction of a second. But only when the external display is connected. The only way I noticed was because my mouse kept stopping and then moved again. I just started an online stopwatch, and that also hacked sometimes and then went on a fraction of a second later. Could a re-install work? Operating my macbook in clamshell-mode was a way to test if the videocard could not run both screens smoothly, but the problem also shows up with only the external display on. Another thing: When running Windows XP there doesn't seem to be any problem at all.. I'm a mac-noob :P First mac ever. [/QUOTE]
