Monitor Specifications
The following sections give you information about the various power
management modes and pin assignments for the various connectors of
your monitor.
Power Management Modes
If you have VESA’s DPM compliance display card or software installed
in your PC, the monitor automatically reduces its power consumption
when not in use. This is referred to as Power Save Mode. If the computer
detects input from keyboard, mouse, or other input devices, the monitor
automatically resumes functioning. The following table shows the power
consumption and signaling of this automatic power-saving feature:
VESA Modes
Normal operation Active Active Active Blue 21 W (Maximum)**
Active-o mode Inactive Inactive Blank Amber Less than 0.5 W
Switch o - - O Less than 0.5 W *

14 About Your Monitor
LCD Monitor Quality & Pixel Policy
During the LCD Monitor manufacturing process, it is not uncommon for
one or more pixels to become fixed in an unchanging state. The visible
result is a fixed pixel that appears as an extremely tiny dark or bright
discolored spot. When the pixel remains permanently lit, it is known as a
“bright dot.” When the pixel remains black, it is known as a “dark dot.”
In almost every case, these fixed pixels are hard to see and do not
detract from display quality or usability. A display with 1 to 5 fixed pixels
is considered normal and within competitive standards. For more
information, see Dell Support site at:
http://www.dell.com/support/monitors.
Maintenance Guidelines
Caring for Your Monitor
CAUTION: Read and follow the safety instructions before cleaning
the monitor.
CAUTION: Before cleaning the monitor, unplug the monitor power
cable from the electrical outlet.
For best practices, follow the instructions in the list below while
unpacking, cleaning, or handling your monitor:
• To clean your antistatic screen, slightly dampen a soft, clean cloth
with water. If possible, use a special screen-cleaning tissue or solution
suitable for the antistatic coating. Do not use benzene, thinner,
ammonia, abrasive cleaners, or compressed air.
• Use a slightly dampened, warm cloth to clean the plastics. Avoid using
detergent of any kind as some detergents leave a milky film on the
plastics.
• If you notice a white powder when you unpack your monitor, wipe it
off with a cloth. This white powder occurs during the shipping of the
monitor.
• Handle your monitor with care as a darker-colored monitor may
scratch 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 power off your monitor when
not in use.

Troubleshooting
WARNING: Before you begin any of the procedures in this section,
follow the Safety Instruction
Self-Test

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 o both your computer and the monitor.
2. Unplug the video cable from the back of the computer. To ensure
proper Self-Test operation, remove the Analog (blue connector)
cables from the back of computer.
3. Turn on the monitor.
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 blue. 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. The monitor will enter
Power Save Mode after 5 minutes if left at this state.
5. Turn o 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.
36 Troubleshooting
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.
