Well odd it worked today.
I have no idea why, i wonder if the oppo was reading the edid of my display the other night, and today the edid of my receiver?
I know from using my pc sometimes it reads edid of my receiver, sometimes it lists my denon video processor.
I dont know how it chooses, but the receiver is offloaded first so it should get that edid first.
Either way its working. But then a person in the video processor mentioned running everything through the denon video processor, then to the receiver, then to my display.
This works well.
