Stereoscopic Output does not work with NVIDIA 3DTV Play on LG Cinema 3D Screen

Dear Experts,

I am trying to build a game (Test Example: Just a red cube on a green plane) to be viewed with PASSIVE 3D Cinema Glasses on an LG TV.

It works perfect on my Rift, it works perfect on the standard screen. The NVIDIA demos and calibrations also work fine, as does the NVIDIA 3D Benchmark.

If I start the game (I have tried windowed, Full HD, 1280*720 among others) the view is strange (like a 2 D view for xy, has the red/green colors of the cube/plane) on the left eye and nothing on the right. All other platforms / outputs show the expected default perspective view of the main camera - cube on plane.

a) has anyone successfully connected a passive LG screen to unity with NVIDIA ? b) does somebody know what and how to configure on the unity/driver/lg side to make it work ? c) has anyone successfully connected an ACTIVE TV set (Samsung, Panasonic,...) to an NVIDIA Graphics card with a unity game ? (If yes, how ... )

Any advise more than welcome ...

Best regards Marc
