I would like to get a couple DL-5500-based USB3.0 DisplayPort adapters, and was prepared to pull the trigger on the Plugable UGA-4KDP, then I noticed it does not support HDCP. This struck me as a bit odd, as I expected it was more-or-less a reference of the DL-5500, which the manufacturer claims supports HDCP. I also noticed that another vendor (Diamond) claims to support HDCP on their product based on the same chipset.
I would much rather give Plugable my money over Diamond, but not having HDCP support is going to make things more difficult for me. Am I going to find that no other DL-5500 supports HDCP (and the manufacturers are giving incorrect info) or why the difference in HDCP support between devices?
