fixing 1280*960*76hz would give you 1280*960*38hz effectively. 38hz is not an appealing refresh frequency imho. conclusion: you'll still need a hardware modification to get something really useable in high res on vga.
the device anders was talking about is called JOYTV by AVERMEDIA, i got a cheap pirate device by REDANT that does the same job but has less inputs etc. i still wouldn't like to use this for a long time on a 20" screen though :-)
