Chapter 2 Adjusting and using your monitor
This section will give you information on adjusting and using your monitor.
Comfort and accessibility
Good ergonomic practice is important to get the most from your personal computer and
to avoid discomfort. Arrange your workplace and the equipment you use to suit your
individual needs and the kind of work that you perform. In addition, use healthy work
habits to maximize your performance and comfort while using your computer.
Arranging your work area
Use a work surface of appropriate height and available working area to allow you to
work in comfort.
Organize you work area to match the way you use materials and equipment. Keep your
work area clean and clear for the materials that you typically use and place the items
that you use most frequently, such as the computer mouse or telephone, within the
easiest reach.
Equipment layout and setup play a large role in your working posture. The following
topics describe how to optimize equipment setup to achieve and maintain good
working posture.
Positioning and viewing your monitor
Position and adjust your computer monitor for comfortable viewing by considering the
following items:
●Viewing distance:
Optimal viewing distances for monitors range from approximately 510mm to 760mm
(20 in to 30 in) and can vary depending on ambient light and time of day. You can
achieve different viewing distances by repositioning your monitor or by modifying
your posture or chair position. Use a viewing distance that is most comfortable for
you.
●Monitor height:
Position the monitor so your head and neck are in a comfortable and neutral (vertical,
or upright) position. If your monitor does not have height adjustments, you might
have to place books or other sturdy objects under the base of the monitor to achieve
the desired height. A general guideline is to position the monitor such that the top of
the screen is at or slightly below your eye-height when you are comfortably seated.
However, be sure to optimize your monitor height so the line of site between your
eyes and the center the monitor suits your preferences for visual distance and
comfortable viewing when your eye muscles are in a relaxed stated.
●Tilt :
Adjust the tilt of your monitor to optimize the appearance of the screen content and to
accommodate your preferred head and neck posture.
●General location:
Position your monitor to avoid glare or reflections on the screen from overhead
lighting or nearby windows.
The following are some other tips for comfortable viewing of your monitor:
●Use adequate lighting for the type of work you are performing.
●Use the monitor brightness, contrast, and image adjustment controls, if equipped, to
optimize the image on your screen to meet your visual preferences.
●Keep your monitor screen clean so you can focus on the screen’s contents.
Any concentrated and sustained visual activity can be tiring for your eyes. Be sure to
periodically look away from your monitor screen and focus on a far object to allow your
eye muscles to relax. If you have questions on eye fatigue or visual discomfort, consult a
vision care specialist for advice.

Chapter 2. Adjusting and Using your monitor 2-2
Quick tips for healthy work habits
The following information is a summary of some important factors to consider to help
you remain comfortable and productive while you use your computer.
●Good posture starts with equipment setup:
The layout of your work area and the setup of your computer equipment have a large
effect on your posture while using your computer. Be sure to optimize the position
and orientation of your equipment by following the tips outlined in “Arranging your
work area ” on page 2-1 so you can maintain a comfortable and productive posture.
Also, be sure to use the adjustment capabilities of your computer components and
office furniture to best suit your preferences now and as your preferences change over
time.
●Minor changes in posture can help avoid discomfort:
The longer you sit and work in front of your computer, the more important it is to
observe your working posture. Avoid as summing any one posture for an extended
period of time. Periodically make minor modifications in your posture to help deter
any discomforts that might arise. Make use of any adjustments that your office
furniture or equipment provide to accommodate changes in posture
●Short, periodic breaks help ensure healthy computing:
Because computing is primarily a static activity, it is particularly important to take
short breaks from your work. Periodically, stand up in front of your work area, stretch,
walk for a drink of water, or otherwise take a short break from using your computer.
A short break from work gives your body a welcome change in posture and helps to
ensure you remain comfortable and productive while you do work.
Eye Strain
●Break Times
Computer users should take some time away from the screen especially if working for
prolong hours. Generally, it is recommended to take short breaks (5 – 15 min.) after
1 –2 hours of continuous computer works. Taking short and frequent breaks is more
advised than longer breaks.
●Looking at Distant Objects
Users often blink less when in front of monitor screen. To minimize eye strain and
dryness, users should rest the eye periodically by focusing on objects that are far away.
●Eye Exercises
1. Alternate looking up and looking down while keeping the body and head upright.
2. Slowly roll your eyes to look to the left and right.
3. Roll eyes to look at objects on the upper right corner and then on lower right. Do
same thing to look at objects on the upper left and lower left.
Low Blue Light
Concerns on blue light affecting eye health have risen over the years. Blue light have
wavelength between 300 nm to 500 nm. The monitors have a factory setting that reduces
blue light emissions. Users can enable low blue light mode on these monitors from the
OSD settings.

2-7 D22-10 Flat Panel Monitor User’s Guide
Selecting a supported display mode
The display mode the monitor uses is controlled by the computer. Therefore, refer to your
computer documentation for details on how to change display modes.
The image size, position and shape might change when the display mode changes. This is
normal and the image can be readjusted using automatic image setup and the image
controls.
Unlike CRT monitors, which require a high refresh rate to minimize flicker, LCD or Flat
Panel technology is inherently flicker-free.
Note: If your system has previously been used with a CRT monitor and is currently
configured to a display mode outside the range of this monitor, you may need to re-attach
the CRT monitor temporarily until you have re-configured the system; preferably to
1920x1080 at 60Hz, which is the Native Resolution Display mode.
The display modes shown below have been optimized at the factory.

Understanding power management
Power management is invoked when the computer recognizes that you have not using
your mouse or keyboard for a user-definable period. There are several states as described in
the table below.
For optimal performance, switch off your monitor at the end of each working day, or
whenever you expect to leave it unused for long periods during the day.
