Thanks again for the quick replies gentlemen!
First, Joevt, to answer your questions, the AVR EDID is not a problem; due to how my setup is configured, the TV is not directly connected into the AVR. No pass through of the TV’s EDID would be occurring.
As for my GPU, it is an ASUS STRIX 970 4GB model and has 2x DVI, 1x HDMI 2.0a and 1x DP. As mentioned, the HDMI port works wonderfully to my AVR whereas the DP does not.
To clarify my configuration, I am running the HDMI directly to my TV for 4K HDR10 (My AVR only supports HDMI 2.0 and not HDR10) and a second DP -> HDMI connection into the AVR.
DP dual mode is supported on my card, you are correct that it is Display Port 1.2. The output video resolution is meaningless to me, as it will be a phantom display. I am more concerned with audio fidelity (hence the use of HDMI for bit-stream pass through versus S/PDIF / Optical.)
David, regarding your response. I would be glad to try a firmware update of the adapter to see if that has any effect. If you want to send me the relevant utility I will give it a try! I will also report back tomorrow, as the passive adapter is set to arrive in the mail (also a Plugable device, you guys make good products and your support is superb.)
Thank you both for your time.
Cheers!
