I have very little doubt that this is being managed by th
Very curious. Normally, one sets up a resolution that matches the aspect ratio of the monitor. You are using a 4:3 aspect ratio resolution but you have a 16:9 monitor. Unless your card does something magic, what's happening is something you probably don't want. You're running 1920 x 1440. Xvideo is taking your 1080 and 720 line high videos and expanding them to 1440 lines high. This goes to your TV. Your TV is then compressing the 1440 lines down to 480. I guess since it is compressing so far you are not losing much. If you had a 1080 line TV this would lose you some resolution. But it's still a pretty odd thing to do. You might want to try some 16:9 resolutions. The bad news is that from what I have seen, the nvidia driver xvideo will not downconvert 1080 lines to 480, I think it wants 600 or 768 or something -- I had this problem when using TV-out. I might recommend you either run at 1920x1080 or 1280x720 or even at both, thanks to xrandr. In this case, there would be no downconverting in your computer or card, just in your TV, which knows how to do it best for its own resolution. > should line up.

It seems a bit strange to me as well, but it If your TV will accept 1920 x 1440, I suspect it can take just about anything!
