[mythtv-users] Xorg config... getting display size correct

[Stephen Rowles]

Hi all,

I now have my lovely new hardware built, and Fedora Core 5 installed 
(because it supports the new via SP1300 out of the box)

I have everything installed and working - YAY!

but only 1 problem, getting the video output to fill the whole screen :(

Currently I have a small 4:3 ratio box in the middle of the screen, and 
cannot figure out how to make the display cover the whole screen.

I followed the instuctions and sample xorg config file from here:

http://www.kingcot.eclipse.co.uk/unichrome/unichromeTvOut.html

but on my Sony 28inch widescreen TV I don't get anything close to 
widescreen.

Its not ever the correct size for the "zoom" setting, as this cuts off 
the top of the screen and still leaves small black bars on the left and 
right.

I've tried starting the desktop and using xvidtune but usually that just 
ends up with the whole screen being unreadable due to sync problems.

Any expert X tuners out there who could help?

Cheers.
