nVidia TV-out
27 April 2004
Status
- TV-out works fine from the S-Video cable, using a configuration in X11 (nvtv not needed)
- S-video to composite conversion doesn't work (but might work with tweaking)
Software and guides
NVTV
The nvtv
project is still alive and kicking (new files released March 2004)
-- check out their forum.
It's a Debian package!
Tool to control TV chips on NVidia cards under
Linux This is a program to control the TV encoder chips on NVidia
cards under Linux, in order to get tv-out with a wide range of
resolutions and sizes, including "overscan" modes.
The developer, Dirk
Thierbach
<dthierbach@users.sourceforge.net>, a young mathematician, is
also a rivatv developer -- the nvtv code derives in large part from
this project.
Nvtv works with nVidia's binary driver and also with the free nv
drivers. The executable is called tvtools. The Debian package appears
to be fully up-to-date (see changelog),
maintained by Roberto Lumbreras <rover@debian.org>
The nvtv package issues this on installation:
Starting NVidia TV-Out server: nvtvd
This allows you to run the gui as a normal user -- just issue nvtv. All
the variables are there! It's amazing how hard it is to find out what's
available in Linux, even in Debian. I even had this package installed
and had no idea it had a gui. The daemon appears to be a novelty.
See man page for commands and /usr/share/doc/nvtv/USAGE.gz for details
-- it's unzipped at /usr/share/doc/nvtv/USAGE.
With regard to the composite issue, the man page says that the option
--connector has the parameter CONVERT, which "compensates for cheap
SVideo to composite converter cables that don't merge both lines". This
could be the solution to the problem.
Basic TV-out configuration
startx -- -logverbose 5
The monitor detection system relies in i2c -- which you
currently have installed (2.6.5), but make sure you have all parts
needed.
In the X11 configuration file, add this:
Option "TVStandard"
"NTSC-M"
Option "TVOutFormat" "SVIDEO"
Option "TwinView"
Option "TwinViewOrientation" "Clone"
Option "SecondMonitorHorizSync" "30 - 50"
Option "SecondMonitorVertRefresh" "60"
Option "MetaModes" "640x480,640x480"
#Option "MetaModes" "1024x768,1024x768"
Source.
Also try this:
Option "TVOverScan" "1.0"
Legal values are decimal values in the range 1.0 (which means overscan
as much as possible: make the image as large as possible) and 0.0
(which means disable overscanning: make the image as small as
possible). Overscanning is disabled (0.0) by default. Source
There may be a problem with the 5336 driver and TV-out on P4 -- see discussion.
See also a possible
problem using the TV in twinview.
Sophisticated TV-out configuration
Here's a cool setup for starting a second X-windows server that plays a
movie and then exits.
TV-Out
mit nVidia Grafikarten
And this variant of the above (source):
- You don switch your existing X-server to the TV
- instead you start another one (accessible with alt+F8 when its
started, switch back using alt+F7)
- configure your /etc/X11/XF86Config(-4)
mine looks like this:

Make your appropriate changes and save it. Then restart X!
You should now be able to start another X Server. Much easier is to
just start a Movie with this script here:
______________________________________________ __________
#!/bin/bash
X -screen TV :1 -ac & sleep 2; DISPLAY=:1 xine --fullscreen "$1"
&& kill
`ps aux | awk '/X\ -screen/ {print $2}' `
__________________________________________________ __________
Save the text above to a file and make it executable using
# chmod u+x filename
Then start the script using:
# filename /path/to/movie/moviefilename.extension
Just kill the TV-Out with ctrl+alt+backspace, you will return to your
first X-Server. Or use Alt+F7 and Alt+F8 to switch between both.
Someone responded,
I'm using a similar method to watch movies, my script
is:
#!/bin/sh
unset DISPLAY
unset XAUTHORITY
xinit $* -- :1 -screen Screen1
When i switch to TV out, my LCD goes blank
