For some monitors and setups ... like TV out you need to create a custom xorg.conf. There are tons of howtos and infos out there on how to do it. Recent versions of X server are working with a temporary configuration file, but I found out that I would prefer to adjust some things by myself. You start doing this by rinning dexconf, the Debian X Configuration tool and then edit the sections that may be of interest for you. Another way to solve you problem is to configure the command line correctly i.e. for intel put into /boot/grub/menu.lst video=i915:modeset=1 this helps X discover the outputs automatically.
