As it turns out, the Black Diamond II 1.4 screen, according to SI, is an excellent 3D material, for those using or planning a 3D projection setup. I was unaware of that, until right after we returned the Black Diamond to Screen Innovations, following this review. Since I'm working with 3D projectors now, SI is sending us another Black Diamond II 1.4 screen, asap, so I can comment on it's abilities to work with projectors like LG's CF3D, the first 1080p 3D projector for the home, that's shipping. I will blog and update this review after we've tested the 3D abilities of this projection screen.
