I currently own a mitsubishi(3800) 1080p projector and a mid range electric screen that I am very happy with. I want to get the optima hd66 to view 3d blu Ray and 3d gaming with ps3. I will use the Mitsubishi for everyday watching in 1080 and the optima for 3d only.

I think I need the optima upgrade kit releasing in January, the HD 66, a new hdmi 1.4 cable, and a dual projector mount.

any limitations to this setup?

any suggestions on the dual projector mounts?

anything else needed for the setup besides the glasses?

any suggestions on glasses that will be the most comfortable to wear?

do I need a special silver screen?

will these projectors work mounted at the same distance (13 feet from screen to 105"screen).

any other suggestions?


thanks you for comments/suggestions.

You won't need specifically a new hdmi 1.4 cable, any high speed hdmi cable will do just fine (hdmi1.3 cables are identical to high speed hdmi cables)


You don't need a silverscreen, these are only required if you use polarised 3D presentation. You are using frame sequential presentation with shutter glasses, you can use any type of screen you want, although a high gain screen is recommended to compensate for the light losses of shutter glasses.


I suggest you get the new version of this projector : HD67, I read it's brighter and has better colour than the previous 3D compatible DLP models.


You can use any type of glasses compatible with DLP-link synchronisation. I don't know the models though so I can't recommend any.

I'm not an optoma specialist , your remark make me doubt about this projector line.


I did not read reviews comparing the two models directly, I first heard about the HD66 back in january when Nvidia 3D vision for projectors released (with support for the Acer H5360 and the optoma HD66 which was to come shortly after, the HD67 is more recent (may or june I think) and also 3D vision compatible so I guess it's a newer improved model.


The review I read about the HD67 compared it only against the Acer H5360, against which the optoma won on all levels.

Do not waist money on OPTOMA, just get another Mitsu like you have now and build Time Parallel full HD 3D system that outperforms everything else on the market.

the reason I was looking at the hd66 is it is so cheap and easy to set up.buying a new Mitsubishi isn't a big deal, but i have no idea where to start to do what u r talking about. is it complicated? do I need special lens? multiple hdmi cables?

Dual projector time parallel approach does give the best picture (it's the setup I use) but it is complicated to set up, complicated to use, requires sources with 2 outputs (one hdmi cable per projector), is currently not compatible with hdmi1.4 since no demultiplexer is available yet and we don't know if any company is actually going to produce one.


Unless you absolutely prioritize picture quality over any other consideration, don't do it.

Just get your HD66 then.

Blackshark,

I would prefer the time parallel approach and am curious as to how are you're separating the two HDMI signals for left and right eye in your system? Did you make your own demultiplexer?

I don't separate hdmi1.4 into two streams.

I don't have hdmi1.4 streams in the first place.

My video source is a computer.


Software is very flexible and there are different possible ways to show pictures to a dual projector setup. Some stereo picture and steereo video players have display modes specifically for dual projectors. But it still isn't plug-and-play since windows does not know the concept of stereo video or dual displays working together. (Windows only knows clones or independant primary and secondary displays). You have to use tricks to get around the limitations of windows.


The only major problem : BluRay 3D video players don't support it. at the moment, you have to re-encode every BluRay 3D movie (which is a very long process)

@irbloody screen is much more important, the DLP's seem pretty much the same, I'd go as far as they are rebadged

RGB LED or laser light sources would make a remarkable difference you know. Sentences like "won on all levels." ... make me go ummmmmm.

Sorry that was a french paper magazine I found at work about two weeks ago, i don't remember the name of the magazine. The article was a pretty generic article about 3D in the living room, not very memorable.


It just had the projector comparison in the corner of the page, they said they tested the two projectors side by side and found the Optoma HD67 offered better brightness and contrast than the Acer H5360 in 2D and 3D modes.

I saw measurement data of both and optoma is lower @ 120hz. Anyway , screen is more important. Not to mention customer service, Acer offers UPS shipping , my pj went to neighbour country, took ~1 week .


Recently read about their 5 year warranty for dead mirrors.

thanks you for comments/suggestions.

If you're only going to use the HD66 for occasional 3D use, I would recommend a tripod (however, you may need to mount it upside down because of the image display will be projected far too high -- placing it upside down will have the opposite effect).


I'm looking forward to this 3D-XL myself. I haven't decided on which 3D projector I want to use with this, but like you, I have a Epson 8100 for daily use, and it's mounted on a tripod (speaker stand ~$30 to $50) and I would most likely buy another one for the 3D projector as well.


I have an 11' vaulted ceiling so mounting a PJ to the ceiling is out of the question for me (DIY'er), so I picked up a speaker tripod. I'm very pleased with the setup and cost about $40.

Would this work? I was curious to know what that "Dual" L & R 1080p for output mode meant. Seeing how the 3D-XL has HDMI 1 & 2 input and Dual 1080P... ah probably not, because then you might need two 3D-XL's - one set for L output going to one projector and one 3D-XL set for R going to the other projector.

The Dual 1080P selection IS for a two projector passive system. You would use 2 3D-XLs to output 1 left and 1 right video stream. Each 3D-XL would require a 3D HDMI 1.4 input. That input could be derived from a 3D Blu Ray player feeding a HDMI 1.4 splitter such as a Sewell SW-29203. The splitter then feeds the same signal to each 3D-XL.

That's correct, however, I'm looking for a more cost effective solution than two 3D-XL boxes (not a computer solution since I'll be coming directly out of a 3D BD player).


I have a couple of leads that may yield something a little later on, but right now, the 3D-XL box (boxes) is the only way to get the HDMI 1.4 signal split into two 1.3 streams.


The advantage (to a dual projector setup) is that passive glasses can be used (low cost, theater quality), the illumination on the screen is about twice as bright as a shutter system, and it's a pretty cost-effective way to go for home projection at the moment.


The downside to this method, is that a second projector and a screen that won't de-polarize the image are needed. I can always use a second projector and the screen isn't a big issue if it's DIY, so, for me, it's the way to go.

Greetings rmcferon.


Lack of HDMI 1.4a support is one of the limitations of BlackShark's passively polarised dual-projector system. Would this issue be addressed by adding the Sewell SW-29203 splitter/3D-XLs combo?


Are there issues with 24/60p?


Many thanks and best regards.
