More info on RedRay the 4k playback tool. It's going to be able to playback 4k video on up to 120 fps. This will require FOUR HDMI connections. Wow.
RED is also going to talk about a new RED Projector that can cast a 4k picture up on a 15' screen. Projected (pun intended) be be less than 10 thousand dollars I suppose we'll see many a Home Theater move into the 4k realm with such a projector if the lumens output is ideal.
