I had a hell of a time setting mine up too. I use TMT5... there was a tab that I missed which was discribing my display. As soon as I chose HDMI 1.4 3D capable display... Voila!! My projector automatically changes to display 3D. It took me like 8 hours of head scratching... Turns out it was a tab I forgot to setup in the software. I was about to order a new HDMI cable (mine is an old 35ft 1.3 cable running through the attic).
