Tim,
Thanks for posting to the forums! The ABV595PRO board is an interface device that should attach to a computer. You can stream things to the computer that is attached to the board and projector, to show videos on the board, but you would first need to attach it to a computer to get a video signal.
Once connected to a computer by VGA cable/USB cable, you can interact with the computer using the board, and you can view video output from the computer.
Does this answer your question? Please let us know if you have any other questions, or if we need to go into more detail.
Thank you,
