I had a somewhat similar issue with my X1900XT. I could not set it to 1920 x 1200, but 1920 x 1080 was doable for some strange reason. Tried many things including uninstalling then reinstalling the drivers. That didn't fix anything.
I figured something in Windows XP must have been screwed up somehow (probably the Registry). A fresh install of Win XP fixed the issue.
I had an issue with my card on my 1080P TV. I had to go into the display and make sure it was properly identifying, I think it was a "plug and play monitor". Then make sure that the refresh rate is set to 60Hz, it wanted to default to 30Hz. Once I changed the refresh rate it would fill my screen.
At least under XP, Catalyst has a setting whereby you can force the option for 1080p. Here is how to get there(in XP, at least) Monitor Properties --> HDTV Support. Now just select 1080p60 from the menu.
