you have a few options..
in the dashboard you can set the VGA resolution to 1024x768...
Depending on the game you'll either get 720p downscaled to about 1024x580 with black bars top and bottom (best quality) or you'll get 480p upscaled to 1024x768 (not HD but will fill the screen). Which one it chooses it completely up to the game itself. The monitor might look slightly better then an SDTV but in my opinion if you have a decent non-HDTV you'd be better off using that.
With that said I was at walmart last night and they had a widescreen 19" monitor that supported 1280x800 for $245
