Doesn't Video Chess do something involving not keeping track of vertical
sync?  ISTR that, on a TV, the TV often has to roll the picture back into
place after the computer is done making its move.

I would expect that any TV (except Eckhard's ;) ) should be able to roll
the picture back into place after a momentary hiccup in VSync.  After all,
it has to synchronize to the sync signal when powering up or changing

Blanking the output for a frame probably is the better solution, though.
