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.  
Cleaning your monitor  
Please carefully follow these guidelines when cleaning the monitor:  
Always unplug the monitor before cleaning.

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.  
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.

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.  
MHL  
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.
