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: Recommended viewing distance between the eye and the monitor
screen is 1.5 x the diagonal of the screen. Solutions in meeting this required distance in
cramped ofce situations include pulling desk away from wall or divider to make room
for monitor, using at panel or compact displays placing the monitor in the desk corner,
or placing the keyboard in an adjustable drawer to create a deeper working surface.
• 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 state.
• 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 reections on the screen from
overhead lighting or nearby windows.
Chapter 2.Adjusting and using your monitor 2-1
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.
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 ofce 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
modications in your posture to help deter any discomforts that might arise. Make use of
any adjustments that your ofce 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.

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 re-adjusted using automatic image setup and the image
controls.
Unlike CRT monitors, which require a high refresh rate to minimize icker, LCD or Flat
Panel technology is inherently icker-free.
Note: If your system has previously been used with a CRT monitor and is currently
congured to a display mode outside the range of this monitor, you may need to reattach the
CRT monitor temporarily until you have re-congured the system; preferably to 1920x1080
at 60Hz, which is a common display mode.
The display modes shown below have been optimized at the factory.
