I get rather weird behaviour with my TV and component out. My TV is a
Sony Bravia KLV-40V300A. 

The TV seems to know the difference between a PC and a more typical
component like a DVD player.

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...)

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.

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.

I did the above testing when I got the TV, so pre-VDPAU, probably around
~173.

Does anyone know if there is a flag I can pass to the video driver to
make it look right in this mode?
Does anyone else see similar issues with different brands/models of TV?

None of the above really worries me as I don't use the component out,
but I'm still curious.
