Horizontal lines (vsynch?) after switching to Nvidia

[MassMan]

I switched from an old radeon 4850 to a gfx 660.
I formatted windows 7 64bit.
I am using default settings in the latest VLC.

Now movies in VLC often have weird horizontal lines. The same effect happens in fullscreen youtube videos.
This was not there before, when I had Radeon. Playback with verbose 2 does not reveal anything other than a lot of "Mouse hidden/shown" events. When I play the exact same files in Windows Media Player the horizontal lines are not there.

I have googled the crap out of the problem, and searched the first few pages of a search on this forum without finding a solution that worked. Any help would be greatly appreciated. I think it's weird that youtube flash videos and VLC share the same problem, yet it doesn't happen in WMP.

Change Video Output to OpenGL.

Change Video Output to OpenGL.

Thanks, that seems to have fixed it.

I did try it previously, but only after I had tried a million other things suggested around the forums. Perhaps default settings and then only OpenGL was what was needed.

Is there any reason NOT to enable "Use GPU accelerated decoding"?



Sort of off-topic, any idea how to fix it for youtube? Using latest Chrome browser.

No clue for Youtube, sorry. Take the youtube links inside VLC:)

It can fail on some machines and some streams.
