In my experience, yes, but...

I have my monitor running at 1152x864 and the TV at 1024x768. The TV
out won't go any higher than that. I ran into the following problems
with this:

* mplayer when run from mythtv thinks full screen is 1152x864, so on
the TV the bottom right part of the picture is missing. There's a
mythtv setup screen which shows how mplayer is called, so this can be
fixed by supplying -geometry arguments

* similarly mythtv itself has to be set to  1024x768.

* xscreensaver thinks the screen is only 1024x768, so there is a border. 

* firefox won't save itself at a size greater than 1024x768.

There may be workarounds for these, but I haven't found them yet. The
relevant part of xorg.conf looks like this.
