[mythtv-users] TV Output Not Filling TV Screen

[Robert Schultz]

I'm running the latest CVS MythTV (as of June 15th or so) with a NVIDIA 
GeForce 4 MX card using the Composite AND VGA out with XFree86 and 
Fluxbox running under RedHat 9.0 on a Athlon XP2800+ system.

I have my XFree86 config file set up with 'two monitors'.
One is my VGA monitor, I set to 1152x864 and hook to the GeForce card 
with the VGA cable.
The other is my television which I have set at 640x480 and hooked up 
with the Yellow composite cable.

The TV picture doesn't fill the screen. There is a 1 inch border around 
the top, left and bottom edges. The right hand side seems to be aligned 
with the edge of the TV okay though.

I've uploaded my XF86Config file so you can look at what it's set up with.
You can find it here: http://www.cosmicrealms.com/XF86Config.txt

I tried playing around with TVOverScan, but since the image isn't 
centered, I think that will just make things worse.
I tried generating a ModeLine using http://xtiming.sourceforge.net/
But the modeline when enabled didn't do any good (I had it in the right 
section).

Someone told me to take a look at 'xsetvid'
I ran it, and it seems to have the controls needed to move the screen 
around and make it bigger, but this seems very wrong when talking about 
a television.
The television should be automatic I would think.
Which leads me to believe it's a signal issue.

Anyways, I'm really hoping someone out there can help me out.

The TV by the way is a Sharp 27 inch 27K-S300 model.


Thanks
