I just got an RS1. I have a DVI cable with two HDM/DVI adaptors on either end. I want to know if these are introduciing artifacts but I don't know how to see these. The RS1 makes film grain and MPEG noise more visible. Is there a set of test paterns that are noise free for me to use?

Hook up a PC via DVI and project the following pictures.

I think that should do the trick. That way you are digital all the way to the projector.
