I finally got the RF glasses and was too eager to try it...only to be disappointed....here are some observations
1) RF glasses are slightly bigger than Optoma-DLP-link (which are also quite big to start with compared to the panasonic glasses, so not really a big deal)
2) They are almost the same shade as DLP-link
3) They are lighter and fold...so will be easier to store (however I concur with a very early poster about hinge life being questionable in the long run)
the bad stuff:
4) I see the RF have refractive index (lense thickness) that varies quite a bit across the lens...so what this means is if you see image quality vary as you look at the same spot on the screen while slightly moving your head...this really is not acceptable to me...Optoma-DLP-link are very flat and have same thickness so you dont remember you are wearing a glass after a while
5) believe it or not, I saw cross talk with RF glasses !!!!!! I swapped btween the two to be doubly sure, but DLP-link had no such issue...this was during the IMAX logo at the beginning of Hubble 3D...also Image looked less poppy with RF...I will compare more movies to see how prevalent this is
6) surprisingly when you set the PJ to DLP-link mode, RF glasses still work, but they dont remove the red-sync-frame so image looks slightly reddish...however I was disappointed to see that RF needed frame invert which is not the case with DLP-link, so you cant use them together in that sense
7) while the DLP-link never once swapped L/R, I saw that with RF it does.....this sucks
8) RF clearly had more flicker...with DLP-link its hardly noticeable....infact I like the fact the DLP-link will stop shuttering once you go to kitchen to get something to drink as they become brighter...they sync back to PJ the instant you return to your seat and look at the screen...this is very desirable functionality
9) all the complaints I had with DLP-link with my old HD66 are non issues with HD33 as Optoma did a fantastic job in integrating DLP-link this time around bottom line,
looks like the hype about RF has evaporated for me and I will be sticking to cheaper but extremely well working DLP-link glasses
