Hello,
   I just read of a 12-bt DAC from Analog Devices. Part #  AD9712,
ECL, 100 million samples per second (MSPS), -67 dBc spurious free
dynamic range (SFDR) worst-case.

   Immediately I thought HDTV. But a better thought is: what could be
done in terms of a computer display?

   I calculate an 1152 x 900 display, with 12-bits per pixel, and say,
71 frames per second. You would then have some extra bandwidth for the
sync signals, say 25% worth. Is that right?

   And I presume video amplifiers to drive the crt deflection yokes
might present a difficulty ...?
