• 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 qu estions on eye fatigue or visual discomfort, 
consult a vision care sp ecialist for advice. 
Quick tips for healthy work habits
The following information is a summary of so me 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 optimi ze 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 particul arly 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 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 us ed with a CRT monitor and is currently 
configured to a display mode outside the ra nge of this monitor, you may need to re-
attach the CRT monitor temporarily unt il you have re-configured the system; 
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.
