Hopefully this will help everyone out:
I received my Optoma HD-66 yesterday (it is used so I don't know exactly how old it is). I attached to to my cheap Dell laptop using the VGA port. Initially the laptop was setup to display 1280 x 800. My HD-66 would not allow me to activate the 3D since it was greyed out. I went into the display settings on the laptop and noticed that it was 60hz. There wasn't an option for 120hz. I then changed the laptop resolution to 1280 x 720. At this resolution it allowed me to changed the frequency to 120hz. I then went into my projector settings and sure enough the 3D menu was now active. I noticed that 2 other laptop resolutions allowed me to select 120hz. They are 1024 x 768 and 800 x 600. I couldn't actually test the 3D though since I don't have the 3d creator box. I am guessing that the 3D wouldn't work though since based on all of the research that I have been doing, that box only outputs 60hz to the projector. There is a similiar box to the 3D creator here on ebay: http://www.ebay.com/itm/3D-Converter...item3cc0b26b99
It shows that it outputs 60hz in the specs and in the FAQ's (question 8), it says that it does not support 120hz projectors. Also, 3dtvcorp sells the same box: http://www.ebay.com/itm/150707399639...84.m1438.l2649
(make sure you read the excellent description). I have the complete specs of this box in an email attachment and it shows 60hz output. I am not sure how the OP got it to work along with a few others (maybe they had older HD-66 firmware)
Then I tried this: I hooked up my 10 year old DVD player to the projector. I played an older 3D DVD called 'Encounters in the 3rd Dimension' DVD (not Bluray). The output of the DVD player was initially set to 16:9 Progressive. The 3D menu on the HD-66 was greyed out. I changed the output of the DVD player to Interlaced and then the 3D menu on the HD-66 became active. I selected DLP-Link and watched the movie in 3D with my DLP link glasses. At first I was shocked that the Projector could play 60Hz Interlaced but then I remembered that this projector supports, '60Hz Field Sequential 3D for Resolutions Up to 480i'.
I was thinking about buying the 3D creator box but based on my testing and knowledge, I don't think that it will work with this projector. My choices are to either buy a new projector (HD-65?) or the 3D-XL. I decided to buy the 3DXL since I will be able to play 3D Blurays besides SBS and it supports Over/Under which Time Warner Cable displays its 3D in.
I am thinking about buying a 3D Panasonic BDT110 Bluray Player or a WD TV Live. I have read that they can play 720p HALF SBS Mkv files but may have problems playing 720p FULL and possibly 1080p FULL/HALF. I am not sure if the file size also affects playback. Can anyone tell me if either of these boxes can play these without a problem? Currently I can play all of them without stuttering on my laptop but not in 3D yet. Also, what software can easily convert 1080p 'FULL' SBS to HALF SBS or even 720p?
