My first projector (and at the time upscaling DVD player) used an HDCP compliant DVI input so I bought a DVI cable. Since then I have purchased a projector that supports HDMI as well as a PS3 and HD-A2. I am running HDMI to DVI adapters on both ends of the cable and while I knew it wasn't ideal just sort of though eh, I'll get around to it. The other day someone mentioned that DVI might not pass blacker than black and whiter than white. Is this true? How likely is it that the HDMI to DVI to HDMI setup is impacting my picture quality (assuming the use of quality connectors)?
