Here's what I had: http://www.walmart.com/ip/Siig-CB-DP...apter/13215726
Bummer. So, not all "Active" DP-HDMI adapters have a power supply? It seemed like all the ones people were linking off of sites found via Google were linking and/or saying that the way to tell an Active from a Passive was the Active had a power supply. I suppose that isn't the case?
Active dual link adapters need an external power supply while active single link ones do not.
(Single link supports up to 1080p while dual link supports up to 2560x1600.)
