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.
