I can't say with certainty yet because I don't yet have my ION board,
but I'm pretty sure that it can because I have several sources and
the 600Hz feature makes a striking difference on all of them. The
motion becomes fluid in a way that I've never seen before. My girl
friend raved about it more than I did: "How is it doing that? It's
like being there", and then when I turned it off in an attempt to
demonstrate that it was quite smooth even with out 600Hz: "TURN IT
BACK ON!!". :-)

It's not without a price. It definitely creates artefacts with
complex objects moving across a complex background, the object
can drag bits of background. The worst is a full screen pan
with a semitransparent logo on the screen. The logo can become
deformed. Most of the artefacts aren't very noticable unless you
are looking for them, and I find them worth putting up with for
the sake of the striking smoothness. I imagine others wouldn't
