Had similar probs as Hasselstrom and solved it like this, also i found u could avoid using step 3a and getaway with a less complicated environment variable.

Im using winXP btw, so if ur using it to try these steps first. They also make do whatever u need on screen1 while xbmc runs on screen2, before i had some issues with every window i opened when xbmc was running, went to screen 2.

BIG creds to Blackkatt.

Try this:

1. Get Ultramon.
2. Copy your XBMC.exe
3. Rightclick where you want your shortcut and press "Paste shortcut"
4. Rightclick your new shortcut, select "Properties.
5. In Target, add -fs. Should look like this: "C:\Program Files\XBMC\XBMC.exe" -fs.
6. Press apply and select "UltraMon - Window" tab. Select "Use custom settings" and choose Monitor2, then also select "Centered".
7. Hit "OK", open the shortcut, should now be displayed on your screen of chooise.
8. Go to your skins settings and choose wanted resolution.
