Bandwidth: In the context of the Internet, bandwidth refers to the volume of information per unit of time that a connection can handle.


Blended image technology: Allows multiple high-resolution images to be placed on the same wide screen.


Double-stacked projectors: Focusing two projectors on the same screen, providing the same overlapped image for extra brightness. This also works as a good backup plan in case one projector fails.
