Do not know what projector, but I bet it is a DCI unit. :) You still using V5 AT screen?

While the pictures look similar the picture I posted in reality is much much brighter but our cameras cannot show this they shut down its iris.

My picture shows the new SIM2 HDR Duo which projects the very high dynamic range needed to properly display HDR.

As a surprise I was going to offer a free system to the person who guessed it was the SIM2 HDR Duo BUT no one guessed it :)

Alan, is there a link to info on the HDR Duo ? I don't see anything on Sim2 USA's website.

Craig good catch. That was because as of most recently it was not an official product more of a concept but thanks to the SIM2 engineering and a host of others including Joe Kane the concept is now in production and offered for sale.

More to follow.

Was coming back to say Sim2 Duo, but too late. :) I figured it out after getting the email on Friday's meeting. :)

I'd love to get something like this to demo in my theater. I've gone through so many different projectors it would be nice to try something so "new" out in my theater.

I always forget, but how much contrast is in a single f-stop? I see it's spec'ed for 9000 lumens. That would be bright enough for a 30 square foot screen to be able to meet the 1000 nit peak white level for "full" UHD BD HDR10 support. Or you could use a higher gain screen, but that gives me great pause. I've seen very few screen materials that would tempt me to move away from my current unity gain screen.

I'd really love to see some sort of technical explanation on how stacking two "low" dynamic range machines on the same screen creates a "high" dynamic range image.

I remember the description from CEDIA talking about how one projector is for the bright content and one for the darker content.  I found this thread that goes into a bit more detail...
http://dci-forum.com/sim2-product-support-forum/16/hdr-projection-sim2-solution/1623/

However the fundamental problem remains, that the light adds between the two projectors, so if the "bright" projector is showing "nothing" (black) it will still be washing out the black level of the "dark" projector.  Or are they putting a shutter or something in the bright projector so that it's output is completely blocked?

FWIW, from the above article, it seems dynamic range is pretty much in line with a standard Lumis as you might expect:
Results
Screen Area 73,6 sqft Screen Gain 1
Illuminance Measurement
Peak White 1020 lx
Black Level 0,045 lx


1020/0.045 = 22,667:1.

So is there really more to this than just a stacked Lumis pair to achieve really high brightness levels?
