Why pin 2 missing in these HDMI adapters?

On a quick look, all the adapters of this kind on eBay are missing pin 2 (seems to be Data2 shield). Any idea why?

The entire purpose of HDMI was to enforce the HDCP protocol by licensing. "The industry" didn't want to see an open source plug like DVI become the standard.

Sorry, but I'm sure you too have never seen an HDMI "Record IN" jack :D

You can probably find a comparable adapter from another vendor that has the full compliment of pins that you desire/require. ;)

Or... just contact the EBay vendor of that particular adapter and ask them.

So that's the key to defeating HDCP: the missing pin 18! :)

And asking Chinese eBay sellers on the items they sell will likely result in:

"Hi friend, I don't know, I only paste the description from the supplier. I don't even have the items available directly to me so I can't check."
