one idea.... perhaps 3d vision 'emulate' CRT monitor...
indeed on CRT monitor, there are a delay between 2 frames => causing a 'black' screen between each frame (delay to move spot at left-top corner of the screen)
using 3d glasses each eye canb see 60 frames/s but beetween 2 frame eye is hidden causing a fake 'black' screen.
(each eye looks alternativly 60 frames and 60 black screen in 1 second)
perhaps on LCD monitor there are not enought delay between 2 frames and so eyes can see previous frame mixed with new frame.....
your opinion about that?
