MHL (Mobile High-Definition Link) (Only for MHL-input Models)
Mobile High-Definition Link is a digital interface for transmitting video and audio from
an external portable device. It is also capable of charging a portable device
(5 V @ 500 mA).
Connecting the devices
Plug the MHL-certified cable into the display's HDMI ® (MHL) port and the portable
device's HDMI ® -out port.
Using MHL
MHL-certified portable devices will automatically display content on the monitor,
provided the output display and audio formats are supported by the portable device.
When the portable device is in standby mode, the monitor will show a black screen or
turn to standby mode, depending on the portable device's output signal.
Due to the difference in size and resolution between the monitor and the portable
device, you may find the display quality not as crisp as it appears on the portable device.
This may be due to the portable device changing the output format.
This monitor only receives content from the portable device. It is not capable of
controlling the portable device.
