TV out | Thinkpad T23 | Linux and Windows
Sunday, January 20th, 2008What I want is to display PC output on my TV (it fits DivX play very well!)
I bought:
_ 4-pin male-male S-Video Cable (Thomson KBV600)
_ Video Adapter From Scart to S-Video + 3RCA(2 audio + 1 video) (Thomson KBV608)
I connect my laptop t23 to my TV (Sony Triniton CRT)
The very first step is to set the LCD monitor resolution to 800×600 that it’s pretty close to the TV one.
I had the same problem both on Linux and Windows. I could see the picture on the TV but it was black and white. Then I solved with this howto:

Basically that says you need to connect the pins 15 to 20 of the scart -> S-Video adapter.
Windows XP
_ Right clicking on the Desktop
_ Settings (I guess you can do it through the Control Panel instead)
_ Video Adaptor OR Video Card OR Hardware
_ Settings
_ Advanced
_ Display Tab
_ Choose TV as an output. Have a look of all the options this tab should offer to you.
Linux
For those computers equipped by a S3 Savage Video Card (as the T23 is), you need the s3switch program.
- List currently attached devices, active devices, and current format
$ sudo s3switch
- Make CRT, LCD, and S-Video (TV) output active
$ sudo s3switch crt lcd tv
- Set S-Video (TV) output format to NTSC
$ sudo s3switch ntsc
On Debian, you would simply launch:
apt-get install s3switch
But there’s a but. T23 users may need to apply the patch attached to this entry to avoid a Segmentation Fault. So you need to download the source of the program [attached, as well].
$ patch s3switch.c s3switch.patch
$ make
# mv s3switch /usr/local/bin
But there’s [one more] but. I can’t compile the source because of a weird inclusion in s3switch.c.
So I download the source of the Debian package
apt-get source s3switch
I apply the patch to it by hand (not through the patch command) and compile with make.
mv s3switch /usr/local/bin
Now it works! Very proud!
