Special notes on LCD monitors
The following are normal with the LCD monitor and do not indicate a problem.
• Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the
power switch and then turn it on again to make sure the flicker disappears.
• You may find slightly uneven brightness on the screen depending on the desktop pattern you use.
• The LCD screen has 99.99% or more effective pixels. It may include blemishes of 0.01% or less such
as a missing pixel or a pixel lit all the time.
• Due to the nature of the LCD screen, an afterimage of the previous screen may remain after
switching the image, when the same image is displayed for hours. In this case, the screen is
recovered slowly by changing the image or turning off the power switch for a few hours.

Tips and information for comfortable use
Computer users may complain of eyestrain and headaches after prolonged use. Users are also at risk
of physical injury after long hours of working in front of a computer. Long work periods, bad posture,
poor work habits, stress, inadequate working conditions, personal health and other factors greatly
increase the risk of physical injury.
Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis or other
musculoskeletal disorders. The following symptoms may appear in the hands, wrists, arms, shoulders,
neck or back:
• numbness, or a burning or tingling sensation
• aching, soreness or tenderness
• pain, swelling or throbbing
• stiffness or tightness
• coldness or weakness
If you have these symptoms, or any other recurring or persistent discomfort and/or pain related
to computer use, consult a physician immediately and inform your company's health and safety
department.
The following section provides tips for more comfortable computer use.
Finding your comfort zone
Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest, or raising
your sitting height to achieve maximum comfort. Observe the following tips:
• refrain from staying too long in one fixed posture
• avoid slouching forward and/or leaning backward
• stand up and walk around regularly to remove the strain on your leg muscles
Taking care of your vision
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive room lighting,
poorly focused screens, very small typefaces and low-contrast displays could stress your eyes. The
following sections provide suggestions on how to reduce eyestrain.
Eyes
• Rest your eyes frequently.
• 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.
viii
Developing good work habits
Develop the following work habits to make your computer use more relaxing and productive:
• Take short breaks regularly and often.
• Perform some stretching exercises.
• Breathe fresh air as often as possible.
• Exercise regularly and maintain a healthy body.
• In order to prevent damage to the monitor, do not lift the monitor by its base.

Connecting the 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 area. No user-adjustment is required.
• Plug one end of the power cord to the AC inlet, 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 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 orange-colored power LED.
Model LED light
On Blue
Power saving Orange
The power saving mode will be kept until a control signal has been detected or the keyboard or
mouse is activated. The recovery time from "power saving" mode back to "on" is around 3 seconds.
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.

Installation
To install the monitor on your host system, please follow the steps below:
Steps
1. Connect the video cable
a. Make sure both the monitor and computer are switched off.
b. Connect the HDMI Cable (Only HDMI-Input Model)
(1) Make sure both the monitor and computer are switched off.
(2) Connect one end of the 19-pin HDMI cable to the back of the monitor and the other end to
the computer's port.
c. Connect the DP cable (only for DP models).
(1) Make sure both the monitor and computer are switched off.
(2) Connect one end of the 20-pin DP cable to the back of the monitor and the other end to the
computer's port.
2. USB Upstream/USB Downstream (Battery Charger)/USB Downstream
Connect one end of the USB cable to the USB terminal of the monitor, and connect the other end
of the USB cable to an appropriate USB port on your device.
Note: The USB downstream port does not provide power while the monitor switch is off.
Note: In some circumstances when using USB 3.0 devices (hard drives or flash drives)and 2.4GHz
USB wireless devices(for example wireless mouse, keyboard, or headphone) at the same time, USB
3.0 devices radio frequency interference may impact on 2.4GHz USB wireless devices, result in a
drop in throughput on the wireless transmission. User may feel delayed response to mouse or
keyboard inputs, missing keyboard characters or mouse commands, decreased operating distance
between the 2.4 GHz USB wireless device and its receiver.
Please refer to the following ways which helps to reduce this radio frequency interference.
1. Wireless dongle was moved away from the USB 3.0 device as possible as you can.
2. If the USB wireless receiver and USB 3.0 device have to be connected at the sameside,
Position your USB wireless receiver as close as possible to your wireless peripheral device (mouse,
keyboard, headphones, etc.) Or use a standard USB extender cable or Hub to position your USB
wireless receiver as far away as possible from your USB 3.0 port.
3. Connect the power cord
Connect the power cord to the monitor, then to a properly grounded AC outlet.
4. Turn on the monitor and computer
Turn on the monitor first, then the computer. This sequence is very important.
5. If the monitor does not function properly, please refer to the troubleshooting section to diagnose
the problem.
