The GT750 is on the Nvidia support list for 3DTV Play. http://www.nvidia.com/object/3dtv-pl...uirements.html
There's a 3DTV Play user guide on the bottom of this page http://www.nvidia.com/object/3dtv-play-overview.html
You'll need to download a recent GPU driver or go with the latest. As far as I know, you'll need to install the Nvidia emitter driver as well or the "set up stereographic 3D" tab will not show up in the Nvidia control panel.
You'll first want to make sure that the Nvidia control panel sees the projector and is listed in the Nvidia control panel. If it is, go to the stereographic tab and check the enabl 3D box. You should see a "Green" Nvidia logo appear, if so, so far so good. I do not think that you will have to do the 3D set up wizard since you are not using Nvidia glasses. But try it, it does sync the frame output to the Nvidia glasses. If it will not complete, no biggie. Try opening a game and setting the resolution to 1280x720. control + t is the hotkeys used to toggle Nvidia 3D. GL it's not always a smooth process.
BTW, Cyberlink is having a 15th anniversary sale of 40% off and plays nicely with Nvidia, it does have bloatware unfortuneatly. Movie Link, Facebook crap, etc. but works very well. TMT5 can be problematic at times for 3D Blu-ray.
