Hi Rob,

Thanks for your reply, but I think we have miscommunicated. Here's a
better explanation from the man page of vout:

        The IRIS RealityEngine provides two video outputs: a RGB
        video output (which is normally connected to the graphics
        monitor), and a composite video output. vout provides an
        easy-to-use graphical interface to control the composite
        output. It also controls several parameters of the RGB video
        output.

        The composite output is available at the BNC connector labeled
             `composite', and at the S-Video connector.

I was referring to the video composite output that goes to the S-Video
connector, rather than the RGB output to the monitor. The composite
output is usually a 646 x 486 portion of the RGB output, if NTSC format
is chosen for the composite signal. So the offsets that I referred to
in my previous note are offsets within the larger RGB output image to
the smaller composite output image.

A note at the bottom of the vout man page says:

        The composite output may not be genlocked.

And according to the setmon man page:

        The setmon command does not control the composite output of
        RealityEngine, which is controlled by the vout command.

I tried out your suggestion with setmon, but the man pages appear to be
correct.

Eric
