Hello, I have a Dell S2716DG monitor and was wondering if it were possible to get HDCP to work over displayport? So far I have gotten it to work with hdmi but I'm using G-SYNC and have it running at 144hz and have been unable to get it to work that way. I  do have a second displayport monitor and hdcp is working on that one. Things that I have tried so far:

Used the same port and cable  as the second monitor as I have verified HDCP works via that cable/port.

Ran the monitor by itself with the second cable to see if there were any conflicts with having 2 monitors.

Updated monitor and video drivers.

Turned off G-SYNC and set refresh rate to 120Hz.

Ran the BD assistant as advised by this site, it states that the connection is analog, not sure why it shows that way but  the Cyberlink one states that the connection is not digital as well. This seems to be the problem.

I have some screenshots as well:

If you need any more information or have anything else I could try let me know. So far I haven't had much success looking this up online.
