Brand new to the forum. I have been reading until my eyes are about to pop out. The more I read, the more confused I seem to get. I bought the Optoma HD33 for my kids' Xmas. Now, needing a screen. I would like to go with some type of fabric but not sure after reading so much. This projector does 3D -- so would like to get a material that will handle the 3D well. However, most movie watching will be 2D. The room is totally dark. It does have a drop ceiling with white ceiling tiles. We do plan on putting up some black cloth with magnets on the ceiling grid to help. I'm wanting to go with a 120" to 125" diagonal screen. Any help figuring this out would be most appreciated.
