- I've had quite good results with a 10 or 12-foot front projection TV
- (SONY) and the SGI Shutter Glasses. Unfortunately, SGI was charging
- c. $5000.00 US for them (I believe they recently had a "sale" when
- they were offered for only $2K).
-
- These use a little infrared transmitter box to switch the glasses at
- 120HZ (!). There is some ghosting, but no more than with the regular
- monitor.
-
- I think they work well, and have some important applications for VR.
- In particular, they work well when you need fairly high resolution
- (EyePhones et al. suck for high-res, most recent advances possibly
- excepted).
