My guess is that it's because you're using it in RGB mode, where the
color and hue controls don't make sense.  To adjust the hue, you'd have
the reds, greens, and blues with each other in certain amounts and then
split them up again to get and RGB signal.  In other words, the hue control
doesn't work because the red, green, and blue are separate and that makes
a hue control a pain to implement.  (Also, you probably don't need it
with RGB and it would degrade the signal quality.)

They _DO_ work in Composite (CVBS) mode, though.  Hook your 1084 up to a
composite video source like a VCR and try them out.
