My setup as input is a Nvidia Shield Pro/Oppo-203-Clone and as Output a Onkyo TX-SR876/Xiaomi 4k UST. Until now setting the Vertex to everything auto has worked out great (excellent device!).
As i got recently a Oppo-203-Clone i have run into an issue with 3D-Movies. The Onkyo is a "Pre-3D-Device" and cannot handle the 3D-Signal. Leaving everything in auto (max video, max audio) is outputing a "1080p23.973 3D-FP 444 BT 709 8b 148 MHz 1.4" signal to my receiver and i have no sound in my 3D movies.
Looking around in the Vertex-GUI i found no obvious setting how to fix this problem. Is there a way to fix this problem with the Vertex? As the Oppo-Clone has an separate audio out hdmi i have found a temporally fix, but i would like to keep my setup simple with only the Vertex.
