I believe (based on the above photos) that those are "video walls", not video projection. It's a fairly new technology that's gaining a lot of popularity. The resolution is still pretty low, but it will undoubtedly improve. Look at the bottom picture of Trey and you can see the individual pixels on the video screens. There is no projection, it's like a huge and scalable video monitor. Panels can be added to create any size you want, and the whole thing is run from a laptop.
