Sorry... shows my A/V knowledge. I thought that the "RCA 
yellow-red-white(black)" was considered "component" and the three line 
video only (red-green-blue) was "composite". So, the answer to your 
question is that I'm trying to do DVI and component out simultaneously. 
As for the TVStandard, I guess I need to consult the manual...

How do I let it detect? Is there something I should run? During install 
it detected only the LCD monitor I had connected. After upgrading to the 
nVidia drivers, I haven't done anything to re-detect anything. Do you 
have an example of the ConnectedMonitor option? Is it something like:
"ConnectedMonitor" "DVI, TV". Just for the sake of clarity, can I assume 
the dual monitor section of the readme includes mixing monitors and TV's 
and not just dual-head displays?
