OK. The glasses are cheap and I can get a pair and check if I can
produce a static image in gimp that would only be visible for one eye
in the Dolby3D glasses using a good IPS panel. If the display can show
dots of sufficiently clean colors for each of the six wavelengths, it
should be possible to produce images consisting of groups of neighbor
pixels emitting primary colors with different brightness to form
TV-like composite pixels. 2560x1600 might be enough to emulate at least
853x800 3D screen.  Checkboard and line-interleave modes look solid
from 1m for me.

To use wavelength multiplexing, your display must be able to produce
your colors using clearly defined sets of primaries (one for the left
view and one for the right view). That is not possible with
conventional displays as far as I can see.

OK. The glasses are cheap and I can get a pair and check if I can produce a static image in gimp that would only be visible for one eye in the Dolby3D glasses using a good IPS panel. If the display can show dots of sufficiently clean colors for each of the six wavelengths, it should be possible to produce images consisting of groups of neighbor pixels emitting primary colors with different brightness to form TV-like composite pixels. 2560x1600 might be enough to emulate at least 853x800 3D screen.  Checkboard and line-interleave modes look solid from 1m for me.
