the PSVR itself doesn't have a power cable, so I guess they needed the 2nd one (which might not necessarily be HDMI, although it looks like similar in the video) for power and maybe other data like from the sensors etc |
Makes sense, yet why not make a proprietory single plug if it does non hdmi complient stuff. Or maybe it doesn't, hdmi can carry power although not all that much, two to boost power? Sensor data can be send back over the return channel encoded as audio.
Perhaps it's engineered to be compatible with a future dual display device or perhaps Sony had a mountain of hdmi connectors left in a warehouse.
Ah nevermind:
The two “heads” are actually an HDMI port and an AUX port, the former feeding the HMD panel with juicy stereoscopic virtual reality awesomeness at up to 120Hz, the latter transmitting ready-to-be-enjoyed 3D audio in one direction and HMD sensor data plus voice chat coming from the HMD in the other. The AUX cable does also power the HMD itself.
