The short throw BenQ projector W1080ST, and its sister projector W1070, both use triple flash 144Hz when being fed frame-packed 3D. I have found the 3D from BenQ W1070 to be particularly smooth. I find the 120Hz that most home 3D projectors provide to be a bit choppy and irritating. (However, the BenQ will operate at a left right alternation rate of only 120Hz or 100Hz with 60Hz side by side, or 50Hz side by side input.)
Public cinemas using the RealD system also use a 144Hz alternation rate.
1. Are you feeding the projector frame-packed 3D from a Blu-ray player, as distinct from side by side from a pc?
2. How do you find 3D video in other situations? Such as at a public cinema, or with an active glasses flat panel TV?
3. Is the degree of eye strain you refer to similar with all 3D Blu-ray discs or have you found some titles more of a strain than others?
Sensitivity to the rainbow effect from the colour wheel depends on the individual. The BenQ W1070/80ST projectors do use a fast colour wheel (I can't remember the speed) and most people don't seem to be affected by it. I myself fortunately am not sensitive to it. (Though I am very sensitive to 3D flicker, which is why I much prefer the 144Hz alternation rate to the 120Hz of other devices.)
How about others watching your W1080ST when fed frame-packed 3D? Are they having issues? If they are, it is possible your projector is faulty.
