Has anyone actually tried to do this? How easy is it to get a VGA card
to sync at 15 kHz, or whatever? I'm sure I looked into trying this a
while back and decided that you could only do it with a couple of
specific graphics cards, and not the "plain vanilla cheapo" graphics
card that that page talks about!

RGB output is a lot nicer than composite (seen that with my DVD player),
although I have yet to modify my dxr3 to output an RGB signal! I do,
however, have a couple of 'disposable' graphics cards to tinker with!
