View source for How to get TV-Out working on ATI graphic cards

This HOWTO should help you enable TV-Out support on your ATI Radeon or ATI Rage based ThinkPad.

{{NOTE|This page is not applicable to recent ATI Radeon Mobility chips. See [[ATI Mobility Radeon X300]] for a discussion.}}

== Using Xrandr with Kernel Mode Setting (KMS)==
{{NOTE|KMS support for radeon chips is still under heavy development. And in particular S-video support was not on the top of the agenda, but it is starting to work with the very latest updates. If you have a distribution that uses KMS by default like Fedora and would like to go back to UMS, boot with the {{bootparm|nomodeset|}} kernel option.}}

Fedora is the only distribution with KMS enabled by default for Radeon chips for now. The only way to get S-video output support, other then disabling KMS, is to use the Fedora 12 kernel-2.6.31.6-159 or later. Alternatively this functionality has been merged upstream in the 2.6.33 kernel. With these kernels you should get something like the following when you run {{cmd|xrandr --props|}}

 S-video connected 800x600+1400+0 (normal left inverted right x axis y axis) 0mm x 0mm
         tv standard:    pal
                 supported: ntsc         pal          pal-m        pal-60
                            ntsc-j       scart-pal    pal-cn       secam
         load detection: 1 (0x00000001)  range:  (1,0)
    800x600        59.9*+

To change the TV mode to NTSC;

{{cmdroot |xrandr --output S-video --set "tv standard" ntsc}}

== Using Xrandr with legacy UMS==

To use the TVout on Radeon 7500 type following:

 {{ cmduser | xrandr --output S-video --set load_detection 1 }}
 {{ cmduser | xrandr --addmode S-video 800x600 }}
 {{ cmduser | xrandr --output S-video --mode 800x600 }}

And set mode PAL or NTSC with:
 {{cmduser | xrandr --output S-video --set tv_standard ntsc }}

If you want to use XVideo overlay on TV, try following command:
 {{ cmduser | xvattr -a XV_CRTC -v 1 }}
