SaX2, Xorg, not playing nice with my HDTV over DVI

5 Jan 2006

      Hi,
I'm trying to use my DLP HDTV as a monitor for SuSE 10.0 base of
MythTV. So far, I can not make it play nice with it. This is the only
"monitor" attached, no other display.

The video card I have is nVidia 5200, and the latest drivers are used.

Now, looking in Xorg.0.log, the TV (monitor) responds that it supports
1280x720 resolution, and reports all its data for modeline. So I
prepared a custom modeline in xorg.conf with this data, and I got it
displayed right. With one exemption - it stretches the picture a
little bit out of the screen (like 20-30 pixels are out of the screen
at every side).

So, I decided that I can use sax2 and it's "move" and "size " buttons
on test mode. Unfortunately, sax can not start from a graphical login
(says something like config file checksum fails, etc.). But xorg
starts OK, no problems and no error entries in the log. Just sax does
not start.

Now, I went in init 3, and decided to start sax from there. It aways
runs in 800x600 mode (which is not native for the monitor) and the
fonts are so small, that I can not see what is written so I can not
change anything to configure.

I tried with -s and --sysconfig options, which are supposed to read my
existing xorg.conf and use it, but it does not happen, it again starts
in 800x600 mode with microscopic fonts.

So, here are the questions - how to add a border outside the total
space reserved for X, so it "shrinks" the real picture in the display
size? Or how to make sax2 to play nice and to use the settings from
xorg.conf.

Bellow are the lines from the Xorg.o.log, where X autoprobes the
monitor, and the relevant parts from my xorg.conf:
