Debating between the BenQ W1070 and the Optoma, with the Optoma having the edge because of the supposed benefit of having a VESA port. I like the idea of RF glasses not losing sync if I look away at the screen to grab a snack or something, but I would have a hard time justifying the extra cost if the difference in contrast is somehow hindered by something I'm unaware of with RF glasses.
I just bought the HD25 this week and I also bought a pair of the Optoma BG-ZF2100GLS glasses as well as the Sainsonic SSZ-200DLB DLP link glasses. I wanted to compare the DLP link glasses vs the RF glasses. I really wanted to like the Sainsonic ones since they are 1/2 the price and I need 6 pairs. On the box of the Optoma glasses it said it handled 96, 100, 120Hz. I would have assumed they did 144Hz but it doesn't say that anywhere. The Sainsonics were labeled as handling 144Hz. I tried my old ultraclear DLP link glasses which are 120Hz and I couldn't get them to work with HD25.
My dedicated theater in the basement is totally light controlled. I'm shooting a 106" diagonal onto an accoutically transparent center stage XD screen with a 1.2 gain. I tested a wide variety of 3D content ranging from vintage black and white with The Creature From The Black Lagoon all the way up to more recent Oz the Great and Powerful. After quite a bit of viewing I can easily say that in my opinion the Optoma RF glasses provided a nicer 3D image. I'm not sure if it was because of the DLP link technology is inferior to the RF or if it was just the fact that the Sainsonics were not as high quality.
The main difference was the Sainsonics had less contrast in the image. It was almost like they had a very faint haze over everything. Blacks were nicer with the Optoma glasses. Not sure if this was due to the DLP sync flash washing things out or the quality of the LCD lenses isn;t as food for the Sainsonics. The image had a slightly greener cast to it as well witht he Sainsonics. I tried to adjsut the image brightness and contrast to make the DLP link mode with the Sainsonics look equivalent to the Optoma RF glasses in VESA mode but I couldn't get an equivalent match without reducing the IQ overall.
I also had a couple of instances where the Sainsonics lost sync. I wasn't looking away from the screen so I'm not sure what caused it. I've been using DLP link glasses with my old Acer H5360 fora coupleof years and they never lost sync unless I looked away from the screen.
If I didn't have the RF glasses to switch back and forth with I would probably be happy with Sainsonics but when compared directly against the RF glasses, they were not as good as the Optomas. After this comparison I'm glad I decided on the Optoma HD25 vs the BenQ 1070 I was looking at. The BenQ only does DLP link for 3D so it doesn't have the RF option. This feature alone makes the HD25 better than the BenQ 1070 in my opinion.
The Optoma HD25 was a definte upgrade over my 2+ year old Acer H5360. I'm glad I made the switch.
