Chapter 2� Adjusting and using your monitor
This section will give you information on adjusting and using your monitor.
Chapter 2. 2-1
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:
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 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 reections on the screen from
overhead lighting or nearby windows.
Note: For displays with glossy bezels the user should consider the placement of the display as
the bezel may cause disturbing reections from surrounding light and bright surfaces.
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.•

Chapter 2. 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
ofce 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 modications in your
posture to help deter any discomforts that might arise. Make use of any adjustments that your
ofce 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.
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.

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 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 congured
to a display mode outside the range of this monitor, you may need to reattach the CRT monitor
temporarily until you have re-congured the system; preferably to 1920 x 1080 at 60 Hz, 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 used your mouse
or keyboard for a user-denable 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.
