• 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 informati on is a summary of some important factors to consider to help 
you remain comfortable and prod uctive while you use your computer. 
•G
G ood  p ostu re  s ta rts  w it h  e q u ip m en t s e tu p: 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.
•M
M in or c h an ges i n  p ostu re  c a n  h elp  a v oid  d is c o m fo rt: 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
•S
S h ort,  p erio d ic  b re a k s h elp  e n su re  h ea lt h y c o m putin g: 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 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 readjuste d 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. 
N ote :   If your system has previously been used wi th 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 1366 x 768 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-def inable 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.

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.
