Recently have a Acer X1261 projector, and tried to connect it with my Computer for NVIDIA 3D vision experience. I set the projector in the less requirements for the 3D vision. The problem the [projector have no DVI-D interface. Tried with the DVI-I to the VGA adaptor with the VGA cable. But after connect with the VGA cable got a message, “it`s not possible to run the 3D stereoscopic mode”. Then tried to connect with the DVI-D cable. But this time the projector gives the black screen, and no signal from projector. How can I able to run my X1261 with 3D vision?
