We are not able to reliably do load detection on the tv dac as of yet
so the connection status is unknown.  You can force the output off by
default in your config.  See this page for more info:
http://www.intellinuxgraphics.com/dualhead.html
you can also force it off at runtime with:
xrandr --output DVI-0 --off
It's an intel page but it applies to any randr 1.2 capable driver.
The driver used to default to unconnected on the tv dac if DDC failed,
but that led to some users not being able to get the xserver up if
they were using an old pre-edid monitor or have a chip with
problematic ddc.
