I am aware that the recent Pico Neo devices (including the upcoming Pico Neo 3 Link) have displayport/hdmi connections, both output and input, for mirroring the VR view onto a TV/monitor or to use PCVR via cable. So I guess it should be technically possible to display other HDMI sources like a Bluray player or a game console inside the HMD, on a virtual cinematic screen.
This feature doesn't seem to be currently supported. Would it be feasible to add it?
