Comfort and accessibility 
Good ergonomic practice is important to get the most from your personal 
computer and to avoid discomfort. Arra nge 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 larg e role in your working posture. The 
following topics describe how to opti mize 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 modify ing 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 yo ur 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 to p 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 op timize 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 light ing or nearby windows. 
 
The following are some other tips for co mfortable viewing of your monitor: 
 
						

							
2-2L1951p Wide Flat Panel Monitor User’s Guide
 
●   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 sc reen to meet your visual preferences. 
●   Keep your monitor screen clean so yo u can focus on the screen’s contents. 
 
Any concentrated and sustained visual activi ty can be tiring for your eyes. Be sure 
to periodically look away  from your monitor screen an d 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 comforta ble 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 you’re your computer, the more important it is to observe your working   
posture. Avoid as summing any one postur e 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 particul arly important to take short breaks from 
your work. Periodically, stand up you’re yo ur 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 welc ome change in posture and helps to   
ensure you remain comfortable and productive while you do work.

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.
Table 2-4. Power indicator
2-6
Table 2-3. Factory set display modes
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
th e image controls.
Unlik e CRT monitors, which require a high refresh rate to minimize flicker, LCD or
Fla t Panel technology is inherently flicker-free.
Note: If your system has previously been used with a CRT monitor and is
cur rently 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 at 60 Hz, which is the Native Resolution Display
mode.
