Default Nvidia TV Overscan/Scaling

Is there any way to support tv scaling or positoning under linux with the nvidia drivers? I see overscan, but there's no positioning settings?

Also, whenever I change resolutions on the fly in X, my overscan setting is lost. Is there any way to prevent this from happening/

Anyone? Are there any planned features in the driver for something like this?

Hear hear! The black bar at the bottom of my tv screen is about driving me apes**t. It REALLY shows up on a big screen. What's the point of porting the nice setup tool, which even adjusts overscan on the fly, if it can't get the damn screen to look good on a TV?

With the MOUNTAIN of technical effort that goes into making these cards this seems an almost absurd problem.

Could we perhaps work around it with some clever horizontal sync mode line black magic in xorg.conf?

Anyone?

All I want is for MythTV to run w/o a black bar at the bottom?

Apologies if this is an RTFM, but *I have searched* on it and read and read, and ended up with nothing but the useless overscan adjustment which will get rid of the black bar if you don't mind losing a portion of the other three sides to do it.

Lets fix this already.

Right. The windows driver supports TV positioning, the linux do not. The linux drivers also lose their settings when you switch res on-the-fly. The first problem is fixable, but Nvidia has to add that to nvidia-settings/the driver. The second might be a problem that revolves around how X/video drivers work. The X server should send some sort of signal to the drivers regarding the res change, but I'm not exactly sure how the internal mechanisms of X work.
