Power management modes
If you have VESA's DPM™ compliance display card or software installed on your
computer, the monitor can automatically reduce its power consumption when not in
use. This is referred to as Power Save Mode*. If the computer detects input from
the keyboard, mouse, or other input devices, the monitor automatically resumes to
function. The following table shows the power consumption and signaling of this
automatic power saving feature.

LCD monitor quality and pixel policy
During the LCD Monitor manufacturing process, it is not uncommon for one or more

Maintenance guidelines
Cleaning your monitor
CAUTION: Read and follow the Safety instructions before cleaning the
monitor.
WARNING: Before cleaning the monitor, unplug the monitor power
cable from the electrical outlet.
For best practices, follow the instructions in the list below when unpacking,
cleaning, or handling your monitor:
• To clean your anti-static screen, lightly dampen a soft, clean cloth with water.
If possible, use a special screen-cleaning tissue or solution suitable for the
anti-static coating. Do not use benzene, thinner, ammonia, abrasive cleaners,
or compressed air.
• Use a lightly-dampened, warm cloth to clean the monitor. Avoid using
detergent of any kind as some detergents leave a milky film on the monitor.
• If you notice white powder when you unpack your monitor, wipe it off with a
cloth.
• Handle your monitor with care as a darker-colored monitor may get scratched
and show white scuff marks more than a lighter-colored monitor.
• To help maintain the best image quality on your monitor, use a dynamically
changing screen saver and turn off your monitor when not in use.

Troubleshooting
WARNING: Before you begin any of the procedures in this section,
fol low the Safety instructions.
Self-test
Your monitor provides a self-test feature that allows you to check whether your
monitor is functioning properly. If your monitor and computer are properly
connected but the monitor screen remains dark, run the monitor self-test by
performing the following steps:
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on t he m oni tor.
The floating dialog box should appear on-screen (against a black background), if the
monitor cannot sense a video signal and is working correctly. While in self-test
mode, the power LED remains white. Also, depending upon the selected input, one
of the dialogs shown below will continuously scroll through the screen.

4. This box also appears during normal system operation, if the video cable
becomes disconnected or damaged.
5. Turn Off your monitor and reconnect the video cable; then turn On both your
computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check
your video controller and computer, because your monitor is functioning properly.
Built-in diagnostics
Your monitor has a built-in diagnostic tool that helps you determine if the screen
abnormality you are experiencing is an inherent problem with your monitor, or with
your computer and video card.
NOTE: You can run the built-in diagnostics only when the video cable is
unplugged and the monitor is in self-test mode.
To run the built-in diagnostics:
1. Ensure that the screen is clean (no dust particles on the surface of the
screen).
2. Unplug the video cable(s) from the back of the computer or monitor. The
monitor then goes into the self-test mode.
