I guess that depends on whether existing VGA automatic switches are suitable for video with a 15.7 kHz (240p/480i) horizontal frequency, as opposed to VGA which rarely dips below 31.5 kHz (480p).

Thanks for responding. I kinda gave up on this project...there were to many variables and too much messing around. I kinda took a turn into Hyperspin and emulation...sure its not the most "real feals" but a huge time saver. I bought a Framemeiser, and have only used it twice. For me it was a waste of $700...kind of a shame that it now just sits in my closet.

Every automatic one I've used was fine with 15Khz horizontal frequency, and also handled composite-sync through the H-sync pins just fine. The horizontal refresh range and sync composition are the only substantial differences between VGA and the traditional RGB semi-defacto-standard.

$700? For $700 I hope you got several Framemeisters!
