I would like to know if its possible to piggy back a second headset or to use something like drone fpv goggles with a 3d HDMI input to share the experience. One headset and sensors would be controlling the experience e.g. flying round in google earth, and the other would just be passive - like the mirror output to a monitor but 3d. My son has a rift headset so I wondered if I supply 5volts via the USB connector but dont plug it in to the PC so no data to cause condusion, and then give it a second HDMI feed from the graphics card - would it be an imersive experience for the second headset wearer? I had thought of just using FPV goggles such as the eachine ev200 FPV goggles because they have a 3d hdmi input for external 3d sources but I gather from researching online that rift video appears rotated through 90 degrees if fed to a monitor for some reason.
