Meant to be Seen

any one there knows how optoma HD 65 3d ready projectors works with Xpand 3d glasses.
I got this to do some RND but i am little bit confused as i dont have and IR signal emmiter.The person who gived me this to test he says i dont need IR signal emmiter for it.

help me please

I noticed you said "3d ready", are these projectors arlready out? I cannot find them! I would really like to get a HD 65 or HD 20, but i can't find any clairification that they are 3D ready.
