If I run 480p, it seems the image is too big for my TV (42" LCD) so the top and sides get cut off.

If I use 720p, the image is very small, it takes up 1/4 of the top left corner of my TV only.

I tried the screen adjust in the settings but it appears that only changes the GUI and not the games. How can I get FBA to display the full image properly? Thanks.
