The problem is that when I use a 720p mkv I have a small image in the middle of the screen. I doesn't cover the full screen as in previous vers.. When I use a 1080p mkv, everything is ok. I use madvr, but the problem is the same with other video output
Thanks

Codec Tweak Tool > Reset settings

If that doesn't fix it, then it may be a problem with your graphics driver. Try updating it.

Thanks a lot.
