Glancing at the Blue Jeans site when discussing HDMI-DVI cables they made an interesting point: "These cables function equally well in either direction: HDMI to DVI, or DVI to HDMI." Based on this statement I wonder if there are cables that don't work in both directions? I was only able to test the Belkin cable DVI out to HDMI in, not the other way around. I am trying to run that cable HDMI out to DVI in. Could this be the problem ?
