1. Connect in a monitor/TV to the VGA(DVI-D) connector
2. Set it up - use xrandr or your favourite gui app
(replace the VGA-1 with DVI-D-1 if appropriate)
$ xrandr --output VGA-1 --auto

3. Disable LVDS - use xrandr or your favourite gui app
$ xrandr --output LVDS-1 --off

Did you restart X after doing that ?

Got distracted there, my bad
