ATI 5700 HD & 32" TV --- Screen resolution Issue

Hey all,

I recently set up a media center using arch as my distro.  Everything works great!  The only problem I have is that my screen resolution isn't perfect.
I have an ATI 5700 HD, I'm using the open source drivers.  I have a Philips 32" 1080p TV --- optimal resolution is 1920x1080.
I'm using gnome, and under System > Administration > Monitors the correct resolution is shown.  However, I can clearly see a half-inch thick border around my screen!  I know this isn't correct, because my old acer aspire revo (using the nvidia blobs) can show the entire screen at the same resolution!
I have no intention of using the catalyst drivers but I fear that I may have to in order to get this working!  Any ideas?
Attached is my xorg.conf config (I know it's unnecessary, but I generated it anyways).

My question: can I have full screen resolution WITHOUT using the closed-source tools & drivers?

Thanks

As always, the answer lay in the wiki/forums:

It was an overscan issue!

xrandr --output HDMI-0 --set underscan off

Now I just have to make it permanent....

I dropped the above into a shell script and added it to gnome startup, which worked but looked ugly.  I then tried creating a .desktop file in ~/.config/autostarts/ but that looked ugly too...
so I added it to ~/.xinitrc as

exec xrandr --output HDMI-0 --set underscan off &

And that didn't work at all.

Anyone have any better way of implementing this on a more permanent (and dare i say elegant) level? I mucked with xorg.conf but that didn't work.
