Hi friends,

I would like to invite your comments on the following 15 second video:
https://www.youtube.com/watch?v=cNSsc9x2ybE

I have purchased a nVidia Quadro K6000 on eBay and have been checking it out.
I'm rather alarmed by this horizontal line that appears on every video I play. You can distinctly see it on the clip I uploaded (link above), when the girl's arm rises up against the blue background, you can see the horizontal lines. Is this the graphics card? Can it be fixed?

I know it is NOT the monitor as I have tried it on two other monitors - Same thing happens.
I know it is NOT that video, as I have tried watching multiple videos, it OCCURS all the time when video is played.

Interestingly, I can only reproduce the problem on YouTube at the moment. I actually downloaded that video to my computer and played it (ie. not through YouTube) and I don't NOTICE the horizontal lines. Could this be YouTube? I haven't noticed this on other computers.

Thanks for any help!


For the fact that it only happens when STREAMING from youtube, but not when the same video has been downloaded, I can only assume that its a sample rate issue with the stream maybe... is it playing in 360p or better when streamed through youtube? Also have you tried another browser to see if its browser related in which the video played on youtube has to work through your browser, but when played locally it might be media player or VLC Player that is playing the video etc in which the problem is not noticed.In addition to Dave's suggestions, it could also be worth turning off HARDWARE acceleration in FLASH and/or your browser just to see if that changes anything.
