Has anyone configured and used NVIDIA component out?
While many of the NVIDIA cards are component capable, frequently including component converters, there seem to very few people who
have reported configuring this in NVIDIA Linux on the net, at least that I can find.
Does this VDPAU analogue composite limitation apply to analogue component as well? (My HD TV only has HD component input - up to
1080i - so it seems fine to display using mythtv in New Zealand for the foreseeable future)
I am hoping component out will also give good HD using VDPAU?
Much obliged

I get rather weird behaviour with my TV and component out. My TV is a Sony Bravia KLV-40V300A. <BR>
<BR>
The TV seems to know the difference between a PC and a more typical component like a DVD player.<BR>
<BR>
When I connect using VGA or DVI/HDMI it switches into PC mode. In this mode everything looks the way you'd expect if you pluged into a standard LCD monitor. A good chunk of the TV menu options are disabled (Colour, Hue, Sharpness, etc...)<BR>
<BR>
When I connect using Component (or sometimes via DVI/HDMI if I've been messing with nvidia-settings) it seems to switch to a standard mode, typically 720p, and in this mode the colours are dark and look terrible. Overscan is enabled clipping the edges from the picture.<BR>
<BR>
I can only guess that a DVD player has a different colour profile from a PC and the TV is trying to compensate. I suspect if I messed with the colour setting within nvidia-settings I could make it look right, but that sounds a great deal like hard work.<BR>
<BR>
I did the above testing when I got the TV, so pre-VDPAU, probably around ~173.<BR>
<BR>
Does anyone know if there is a flag I can pass to the video driver to make it look right in this mode?<BR>
Does anyone else see similar issues with different brands/models of TV?<BR>
<BR>
None of the above really worries me as I don't use the component out, but I'm still curious.<BR>
