Re-Design your site to take full advantage of the screen. I'm using a wide screen monitor and your site fills less than half of it.

This happens by coding in hard widths on your "tables" which get used to format the screen. If you use a percentage instead of pixel width, your site will spread out and fill the screen It will still look the same to someone with a small screen, but will look a lot more relaxed and open to someone with a wide screen. To me, the content jammed in the left hand corner like it is, appears very busy and crowded.
