I have tried all of the options in my Oppo BDP-93 player. All of the options in the Outlaw Audio 975 and all of the options in my Panasonic PT-AE8000U projector.
The 3D movie (Gravity) will start with 2D logo and then the face plate of the Oppo will display Top Menu but there is nothing on the projector screen and the player is locked. Remember that regular 2D Blu-ray's work great from the Oppo to the 975 to the projector. Remember also that 3D video works great from the Oppo to the projector. I know very little about HDMI. It appears that the Outlaw is breaking the handshake between the Oppo player and the Panasonic projector. I just noticed this item from outlaw. I says that it will make 4K work but it does not mention 3D. https://www.outlawaudio.com/products/975.html Read the red and click on TE HDS-42AVR. If 4K is passed, will 3D also pass? I have tried 3 different HDMI cables and also a HDMI repeater in line. No go.
