Weird Pixel Problem

[avigotsky]

Hey,
Just today I noticed my MBP had a separation/lag of pixels... here's a video

Earlier in the day the pixel line was about 50px from the bottom of the screen. I restarted and it was gone for a little bit, but now it's back and in a different place.

Any help/advice would be appreciated.

Thanks,
Andrew

That looks like a classic screen refresh outside of the vertical blanking interval (V-sync issue). No idea how this relates to Macs though. Video settings? Try checking your refresh rate.

All my video settings are still default (60hz I'm pretty sure). When I disconnect my other monitor from the MDP it seems to fix the problem?
