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 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 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 lightly 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.
Quick tips for healthy work habits
The following information is the summary of some important factors to consider to help 
you remain comfortable and productive when you use 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 when 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 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.

Caring for your monitor
Be sure to turn off the power before you perform any maintenance on the monitor.
Do not:
• Apply water or liquid directly to your monitor.
• Use solvents or abrasives.
• Use flammable cleaning materials to clean your monitor or any other electrical 
equipment.
• Touch the screen area of your monitor with sharp or abrasive items. This type of 
contact may cause permanent damage to your screen.
• Use any cleaner which contains an anti-static solution or similar additives. This may 
harm the coating of the screen area.
Do:
• Lightly dampen a soft cloth with water and use this to gently wipe the covers and 
the screen.
• Remove grease or finger marks with a damp cloth and a little mild detergent.
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 1600 x 900 at 60 Hz, which is the Native Resolution Display mode.
The display modes shown below have been optimized at the factory.
