Thanks Dylan.
There is old SD RGB and new HD YPbPr that both use the set of coloured red, green and blue cables. Perhaps that is the distinction
you are finding?
I append some NVIDIA readme material on this which may help some people.
I believe the line should be in your X config file to force component, something like:
Option "TVOutFormat" "COMPONENT"
Perhaps that is why it did not appear correct?
The thing I am not sure about is which section of the many sections should this line go?!
Kind regards
David
To use your TV with X, there are several relevant X configuration options:
o The Modes in the screen section of your X configuration file; you can use these to request any of the modes in the mode pool
which the X driver created for this combination of TV standard and TV encoder. Examples include "640x480" and "800x600". If in
doubt, use "nvidia-auto-select".
o The "TVStandard" option should be added to your screen section; valid values are:
TVStandard Description
------------- --------------------------------------------------
"PAL-B" used in Belgium, Denmark, Finland, Germany, Guinea, Hong Kong, India, Indonesia, Italy, Malaysia, The
Netherlands, Norway, Portugal, Singapore, Spain, Sweden, and Switzerland
"PAL-D" used in China and North Korea
"PAL-G" used in Denmark, Finland, Germany, Italy, Malaysia, The Netherlands, Norway, Portugal, Spain, Sweden, and
Switzerland
"PAL-H" used in Belgium
"PAL-I" used in Hong Kong and The United Kingdom
"PAL-K1" used in Guinea
"PAL-M" used in Brazil
"PAL-N" used in France, Paraguay, and Uruguay
"PAL-NC" used in Argentina
"NTSC-J" used in Japan
"NTSC-M" used in Canada, Chile, Colombia, Costa Rica, Ecuador, Haiti, Honduras, Mexico, Panama, Puerto Rico, South
Korea, Taiwan, United States of America, and Venezuela
"HD480i" 480 line interlaced
"HD480p" 480 line progressive
"HD720p" 720 line progressive
"HD1080i" 1080 line interlaced
"HD1080p" 1080 line progressive
"HD576i" 576 line interlace
"HD576p" 576 line progressive
The line in your X config file should be something like:
Option "TVStandard" "NTSC-M"
If you do not specify a TVStandard, or you specify an invalid value, the default "NTSC-M" will be used. Note: if your country
is not in the above list, select the country closest to your location.
o The "UseDisplayDevice" option can be used if there are multiple display devices connected, and you want the connected TV to be
used instead of the connected CRTs and/or DFPs. E.g.,
Option "UseDisplayDevice" "TV"
Using the "UseDisplayDevice" option, rather than the "ConnectedMonitor" option, is recommended.
o The "TVOutFormat" option can be used to force the output format. Without this option, the driver autodetects the output format.
Unfortunately, it does not always do this correctly. The output format can be forced with the "TVOutFormat" option; valid values
are:
TVOutFormat Description Supported TV
standards
------------------- ------------------- -------------------
"AUTOSELECT" The driver PAL, NTSC, HD
autodetects the
output format
(default value).
"COMPOSITE" Force Composite PAL, NTSC
output format
"SVIDEO" Force S-Video PAL, NTSC
output format
"COMPONENT" Force Component HD
output format, also
called YPbPr
"SCART" Force Scart output PAL, NTSC
format, also called
Peritel
The line in your X config file should be something like:
Option "TVOutFormat" "COMPONENT"
o The "TVOverScan" option can be used to enable Overscan, when the TV encoder supports it. Valid 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.
The NVIDIA X driver may not restore the console correctly with XFree86 versions older than 4.3 when the console is a TV. This is due
to binary incompatibilities between XFree86 int10 modules. If you use a TV as your console it is recommended that you upgrade to
XFree86 4.3 or later.

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
David
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.
Dylan
