Default Re: 1080i Bug with Component Video Output 6150

Thanks, this fixed my problems too. I added lines to my xorg.conf file so it now looks like:

Section "Device"
Identifier "Videocard0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 6150"
Option "AddARGBGLXVisuals" "False"
Option "TVOutFormat" "COMPONET"
Option "TVStandard" "HD720p"
# Option "TVStandard" "HD1080i"
# Option "TVOverScan" "0.5"

I uncomment either the HD720p or the HD1080i lines and the component video output has good color and is crisp in either mode. But........

I too have this same problem and am working on it. What I would have done is to build some mode lines to get things to work but the Nvida readme on there driver is explicit is saying: “Additionally, the NVIDIA driver contains a hardcoded list of mode sizes that it can drive for each combination of TV encoder and TV standard. Therefore, custom modelines in your X configuration file are ignored for TVs.” Under windows XP this does not seem to be a limitation as one can set overscan independently for vertical and horizontal picture size with the TV out. I have tried the TVOverScan option in the Nvida driver and it does not seem to have any effect. I don’t know what our options are at this point as the driver seems limited.
