This issue is related to the way the receiver handles the projector's display information. Most receivers will pass through the display's information from the projector to the computer. However some receivers will apply their own display information and cause the NVIDIA GPU to not detect it properly.

You can workaround this problem by using a Gefen HDMI Detective Plus module device which allows you to program the projector's EDID and pass that information to your computer.  With this device, the connection diagram would be as follows: PC with GeForce GPU >> Gefen HDMI Detective Plus >> Receiver >> 3D Vision projector
