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. For more detailed information on
any of these topics, visit the Healthy Computing Web site at:
http://www.lenovo.com/healthycomputing/.
Arranging your work area
Use a work surface of appropriate height and available working area to allow you to work in
comfort.
Organize your 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 your monitor
Position and adjust your computer monitor for comfortable viewing by considering the
following items:
• 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 office
situations include pulling desk away from wall or divider to make room for monitor, using
flat 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 reflections on the screen from
overhead lighting or nearby windows.
Chapter 2. 2-2
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 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 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 with
your computer, the more important it is to observe your working posture. Avoid assuming
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 from 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 of the monitor uses is controlled by the computer. Therefore, refer to your
computer documentation on how to change display modes.
The image size, position and shape might be changed 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 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 reattach the CRT monitor
temporarily until you have re-configured the system; preferably to 1920 x 10 at 60 Hz,
which is a common 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 used 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.
