I already asked my TV Led by LG gave me 720 x 483 VGA resolution, but only with Homebrews, Dreamcast games native -booting with black screen:

There is something you can do about it?
On the other hand I know there Homebrews operating at 720p , and I remember a version of OpenBOR that allowed me to work in several resolutions although slow since I never optimized in Dreamcast.
