Your kidding me!! Im wondering how that is possible. According to Amazon info for the Sanoxy hdmi to vga adapter:
video output: VGA 640×480@60hz,800×600@60hz,
I wonder how that is working when it claims it can only do in 60hz..You need 120 hz to do the 3D for that projector. This doesn't making sense. How is that sanoxy hdmi to vga adapter putting a 60 hz signal into your projector and coming out 3D at stand able frame rates?..If that is something that can be done then someone like me who has a 120hz viewsonic pjd6211 that only has a vga and no HDMI port could use this to use the Optoma 3d-xl. How in the world did you get that to work??? wish more technical people would comment on this because this gives alot of opportunity for people. but in that case you could have just gotten lucky.
