Hi, im looking for a projector to be used with shutterglasses, any suggestions? Which works with shutterglasses- lcd, crt or dlp? I've tried researching it but i can't find anything conclusive. | ||

CRT technology works perfectly with shutterglasses, which some call alternate-eye. But it's expensive, heavy and dim. Also, low-persistence phosphor is required. Some people claim they have got LCD to work "adequately", but I have yet to see a demo that was acceptable in the sense that you could show it off in public. To avoid flicker, the alternation frequency needs to be up above 85 HZ or so, and most LCD panels can't switch that fast, which results in excessive crosstalk. The only DLP solutions I know of that work alternate-eye are too expensive for the casual user. They use 3-chip projectors as the 1-chip models need to use the time domain for reproducing colour. I would be very interested in hearing about news, developments, or simply that I'm wrong :-) about any of the above. | ||

Alatar, You are right. With LCD projectors the problem is not only low ref rate. These projectors do not sync on the PC VGA signal, and generate their ref rate internally. There are some 1-chip DLP models that sync on PC VGA signal. These projectors can be used for 60Hz page flipping, which is not fun to watch. If you are interested in 3D projection display, you may want to look into my new polarizing filters, which have almost 70% transmission (work with LCD only). Drop me a mail and I will tell you more.
