Smile Dual projectors

Question,May or not,be right place to post.
How can I shoot dual digital projectors at my screen?
I realize two cables connected to the receivers hdmi output are needed, one to each projector.
My question is how can I have both projectors adjusted so they
are synchronized on the screen looking as one.
I know it's been done many times with CRT projectors successfully,
But I have'nt seen it done with single lense digital projectors.
I have two projectors,panny's ae8000 and ae4000 both 1080p, can
It be done and how ? Sorry for the request here,it seems this area is
Pretty technical and thought I may find an answer here.
Thanks

I have not seen a stacked digital PJ setup, and I've seen my share of home theaters. With CRTs, there were two choices: stacked or blended. Each is very difficult.

Blended would be for 2.35 screens; stacked would be for a normal 16x9 screen. It sounds like you're asking about stacking, which is simply overlapping the images. I don't think it would be possible to stack 2 digitals without sacrificing focus. In theory it should be possible, but in practice just the tiniest difference in lens shift, yaw/angle, chromatic aberration, etc could make a huge difference. Also I wonder what it would look like if there were any difference in input lag.

In short- you could try it, but I think you're going to have some serious issues no matter how hard you try.
