Welcome to Mint rggavlmf
The maximal resolution specified for you video card is
2048x1536
but that seems a bit unrealistic to me.....
You won't get much 3D at resolutions above 1280x1024.
You have tried to change screen resolution from the menu?
Run in a terminal

Code: Select all

sudo dpkg-reconfigure -phigh xserver-xorg
You will meet a guide to configure you xserver - which is the graphic interface - and you answer a series of questions, among them screen resolution. If you don't know, leave it at the default value.
First you have to find out what resolutions your monitor wants.

Monitors as large as 30 inch are not quite the same as ordinary computer monitors....
I've had a lengthy conversation with a hardware guru about this and feel the need to write a guide, it is really complicated....
You said Mint gives you a maximum of 1280x1024
and that XP at that resolution covers the whole screen, have I got it right?
Check the vertical refresh so it's about 60 Hz in both cases.
I should be...
If so Mint shows you "what's there" while in XP the driver makes your pc interpolate pixels so the screen is filled out.
You will never be able to watch decent HDTV with a Radeon 9200 (if at all)
In the mean time does the monitor have 720P resolution?
You could try to manually edit xorg.conf
backup first

Code: Select all

sudo cp /etc/X11/xorg.conf xorg.conf.bak
Then edit

Code: Select all

sudo gedit /etc/X11/xorg.conf
In 'Section "Screen" ' there is a subsection something like this

Code: Select all

SubSection     "Display"
        Depth       24
        Modes      "1280x1024" "1024x768" 
    EndSubSection
Add

Code: Select all

"1366x768" "1280x720"
in the beginning of the ' Modes ' line.
You might be able to select these in the "Sreen resolution" applet in the Menu
There may be a "Modeline" instead - post back and I'll entangle it...
If it doesn't make sense tell me - I just learned a lot about large monitors and resolution and HDTV and DMI and.....
haven't digested it yet

720P is supposed to be 1280x720 but is in fact 1366x768 - don't ask me why :)
If you calculate 1024/1366 you get 0,75 while you have 768
as vertical resolution in both cases.
So you should have black borders, unless the resolution somehow is changed to widen the image. Thats what happens in XP obviously...
More info soon

I'll have some more chats with the guy who knows HDTV. That it dont fill out has something to do with how pixels are handled - 720P is low by computer standards on 30 inches. But I want to get more info before digging into this :)
It is complicated - believe me
