Connection Examples

When the projector only has one HDMI port, make sure you connect the HDMI cable to the [HDMI1/MHL] port.

You may not be able to connect an MHL cable to all devices. Also, depending on the model or settings of the device, images may not be projected correctly.

When connecting an MHL cable, make sure the cable meets the MHL standards. If the cable does not meet the MHL standard, the connected device may malfunction.

If you connect using a commercially available MHL-HDMI conversion adapter, you may not be able to charge the connected device or you may not be able to perform operations from the projector's remote control.

If images are not projected correctly using an MHL cable, disconnect and then reconnect the MHL cable.

If you switch the HDMI1/MHL source and the HDMI2 source while playing a movie, the movie may freeze. Stop the movie before switching sources.

Connect the ports in either of the following combinations. When using [Computer1] input port [Audio1] port When using [Computer2] input port [Audio2] port

For projectors which audio can be input with the USB cable in the USB Display function, there is no need to connect the audio cable.

Be sure to connect the projector and the computer directly, not via a USB hub.

Connecting with HDMI Cables

If you use a thick HDMI cable, it may disconnect under its own weight. Use the HDMI cable clamp to secure the cable.
