I suggest to use NVIDIA 3DTV Play when you don't have the NVIDIA glasses, it is free if you have the NVIDIA 3D VISION kit (IR emitter etc...) otherwise you need to pay for it.
But it is "included" in the nvidia driver and if you plug in the nvidia IR emitter the 3DTV Play software will be activated. So lets just emulate the IR emitter
*You need a 3D Vision compatible graphics card, you need a 3D Vision compatible display (tv, monitor, projector).
*Install the (latest) nvidia geforce graphic drivers + stereoscopic support
*MS Device Simulation Framework
*Extract the above zip archive, run DSFx64Runtime.msi (64bit) or DSTx86Runtime.msi (32bit) as administrator. After installation run init_x64.bat (64bit) of init.bat (32bit) as administrator.
*By running enablestereo.bat (as administrator) you emulate the IR transmitter and you can select in the nvidia control your 3D display when setting up stereoscopic. When you don't want to run the bat file each time manually, you can put him also in your startup directory: C:\\Users\\UserName\\AppData\\Roaming\\Microsoft\\Windows\\S tart Menu\\Programs\\Startup
and edit the bat file from
start cscript enablestereo.wsf
start /min cscript "C:\\DirectoryWhereYouExtractedTheZipArchive\\enablestereo.ws f"
It is possible you need to reboot your computer.
Now turn on your projector and setup the projector for 3D mode.
Go to the nvidia control panel, setup your projector as the main display and set the resolution to 1280*720 @ 120Hz.
In the nvidia control panel, go to set up stereoscopic 3D. Enable Stereoscopic 3D. Now you should be able to select your projector at "Stereoscopic 3D display type". Run the stereoscopic wizard (don't forget to turn on your glasses).
When playing 3d content with powerdvd/totalmedia theater/stereoscopic player don't forget to select "NVIDIA 3D VISION" as the 3D viewing method.
