Connecting Multiple Projectors of the Same Model

You can connect up to four projectors of the same model in the same room to project a single unified image (BrightLink 1485Fi+).

Note: The interactive features are available only when connecting two projectors (DuoLink). The two projectors must be synchronized using a stereo mini cable and a USB-A to USB-B cable.

Connect the computer and the projectors using HDMI cables as shown.

Note: If you are connecting three or more projectors in a non-interactive setup, connect the projectors in a chain as shown.
If you are using interactive features, connect one end of the stereo mini cable to the SYNC Out port starting from the projector on the left, and connect the other end to the SYNC In port on the other projector.
If you are using interactive features, connect the computer and the projectors using USB cables as shown.

Note: When you set the USB-B2 setting to Off in the projector's Pen/Touch menu, connect the USB cable to the other projector's USB-B1 port. When you set the USB-B2 setting to anything other than Off, connect the USB cable to the other projector's USB-B2 port.
After making the appropriate connections, you need to adjust the necessary projector menu settings. Click the link below.
Note: You may need to restart the projector. Follow the on-screen instructions.
