    That's the back of an older projector. What the heck is the input under S-Video labeled "RGB"? It looks much bigger than the VGA output to the right. I was thinking maybe it was like before VGA, but the output is VGA.

    Anyone know what that is?

    Whats the make and model number?

    This RGB port will be your video in from your video source i.e your Mac.
    I would have thought that the port should have H-sync and V-sync pins as well as RGB and RGB ground. This should then enable you to input from VGA/SVGA ports.

    The Sharp projector model XV-Z4050 had a 15 pin port on. Japanese Model

    It looks like the video port on my old beige G3 (DA-15, I think it's called). I don't have it on hand, but I believe that it's a similar format to VGA and can be converted to DE-15 (VGA) easily.

    I will confirm that. Just counted the pins for it. :)

    Old Apple machines used the different connector, to use Apple monitors at the time, but you were given an adapter to used standard VGA monitors.

    I didn't really figure it out, but it's some special cable that the projector manufacturers (Lightware/Proxima/CTX/Optoma) still currently sell.
