Hi, lately i'm having issues on my mac pro with the video signal. no huge things, but the video signal comes a fraction later (1 or 2 frames) than the audio. i'm on a mac pro (2009) with a custom video card (gtx 680) and a 27 inch mac monitor. it's pretty annoying because when i want to deliver something like a music video to a client i'm never 100% sure if its running sync. i can test it on an imac but that shouldnt be necessary.
also, i tested different monitors and different cables with no better results so i really has something to do with the mac.
any thoughts on how i can check/fix this?
thanks in advance!
