Try to see if you are able to "hustle" someone from Red to give up some info on what sort of imaginer system they use for the RedRay Laser projector.
Or at lest attend the screening of the "Loom" short, and try to see what sort of imaginer is in use (Lcos,DLP,LCD,GLV,Scanning, Mems etc.).
It should be better today or tomorrow than yesterday, as they have improved the projector some by enable it to show 4K 3D for each eye.
There should also be a screening of a movie called "Timescapes" somewhere which should be in 4K 2D.
