Hi all, possibly a silly question. I'm looking to buy projector with 3d capability. I have the Z9X model, question - the 2d to 3d option, does this mean that the system can up scale for example a 2d 4k mkv file, and it will convert to 3d, and play correctly via a 3d projector. Or does the movie file/disc actually have to be 3d in the first place to work?? Thank you
