• Give your eyes regular breaks by looking away from the monitor and focusing on a distant point.
• Blink frequently to keep your eyes from drying out.

Display

• Keep your display clean.
• Keep your head at a higher level than the top edge of the display so your eyes point downward when looking at the middle of the display.
• Adjust the display brightness and/or contrast to a comfortable level for enhanced text readability and graphics clarity.
• Eliminate glare and reflections by:
  • placing your display in such a way that the side faces the window or any light source
  • minimizing room light by using drapes, shades or blinds
  • using a task light
  • changing the display’s viewing angle
  • using a glare-reduction filter
  • using a display visor, such as a piece of cardboard extended from the display’s top front edge
• Avoid adjusting your display to an awkward viewing angle.
• Avoid looking at bright light sources, such as open windows, for extended periods of time.

Developing good work habits
Develop the following work habits to make your computer use more relaxing and productive:

     Note: Take care when performing the installation to avoid injuring yourself.

In order to prevent damage to the monitor, do not lift the monitor by its base.

Screen position adjustment

To optimize the viewing position, you can adjust the monitor tilt, using both of your hands to hold the edges of the monitor. The monitor can be adjusted to 15 degrees up or 5 degrees down.

Connecting the adapter and AC Power cord

• Check first to make sure that the power cord you use is the correct type required for your area.
• The monitor has a universal power supply that allows operation in either 100/120 V AC or 220/240 V AC voltage areas. No user adjustment is required.
• Plug one end of the AC power cord to the Adapter, and plug the other end into an AC outlet.
• For units using 120 V AC: Use a UL-listed cord set, type SVT wire, and plug rated 10 A/125 V.
• For units using 220/240 V AC: Use a cord set consisting of an H05VV-F cord and plug rated 10 A/250 V. The cord set should have the appropriate safety approvals for the country in which the equipment will be installed.

Power saving

The monitor will be switched to “power saving” mode by the control signal from the display controller, as indicated by the blinking blue light.

Display Data Channel (DDC)

To make installation easier, so long as your system supports the DDC protocol, the monitor is able to plug and play. The DDC is a communication protocol through which the monitor automatically informs the host system about its capabilities; for example, supported resolutions and corresponding timing. The monitor supports the DDC2B standard.

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.
