Even if displays were to accept a high referesh-rate signal, there are two
(1) the publisheed response times are usually gray-to-gray, not
full-on-to-full-off. At 120 Hz stereo 3D, the display needs to go full-off
to full-on and back to full-off in 8.3 ms total (roughly equivalent to 4 ms
white-to-black response time).
(2) to be equivalent to a CRT and thus work with existing emitters and
shutter glasses, there can be no delay involved in converting the analog
SVGA signal to a digital image. Based on what I've seen experimenting with
stereo 3D oon LCDs, this isn't normally true -- updates are shifted out of a
phase relative to an equivalent CRT.
I'm optimistic that high-end LCDs will eventually get there in terms of
response, eliminating issue (1). However, the phasing problem (2) may
require special hardware to solve.
