> Source (Plays back unaltered, for spanned dual projector or new model 3DTV)
> Monoscopic (Shows left or right eye of stereo stream only)
> Dual Screen Output
> NVIDIA Stereo Driver (3D Vision)
> StereoBright™
> Quad Buffered OpenGL (hardware page-flipping)
> Sharp 3D Display
> 3D Enabled DLP-TV (uses checkerboard format)
> iZ3D Monitor
> Tridelity SL Series 3D Displays
> SIS Attachment 4
> Side By Side
> Over/Under
> Row Interlaced
> Column Interlaced
