20 | About Your Monitor

Plug-and-Play

You can install the monitor in any Plug-and-Play-compatible system. The monitor
automatically provides the computer system with its extended display identification data
(EDID) using display data channel (DDC) protocols so the computer can configure itself
and optimize the monitor settings. Most monitor installations are automatic; you can
select different settings if desired. For more information about changing the monitor
settings, see Operating the Monitor.

LCD Monitor Quality and Pixel Policy

During the LCD monitor manufacturing process, it is not uncommon for one or more
pixels to become fixed in an unchanging state which are hard to see and do not affect
the display quality or usability. For more information on LCD Monitor Pixel Policy, see
Dell support site at: http://www.dell.com/support/monitors.

illustrates how to extend the stand vertically.

Operating the Monitor | 41

Rotating the Monitor

Before you rotate the monitor, your monitor should be fully vertically extended (Vertical

Extension) and fully tilted (Tilt) up to avoid hitting the bottom edge of the monitor.

NOTE: To use the Display Rotation function (Landscape versus Portrait view) with

your Dell computer, you require an updated graphics driver that is not included with
this monitor. Todownload the graphics driver, go to www.dell.com/support and see
the Download section for Video Drivers for latest driver updates.

NOTE: When in the Portrait View Mode, you may experience performance

degradation in graphic-intensive applications (3D Gaming and etc.).

Adjusting the Rotation Display Settings of Your System

After you have rotated your monitor, you need to complete the procedure below to
adjust the Rotation Display Settings of your System.

NOTE: If you are using the monitor with a non-Dell computer, you need to go the

graphics driver website or your computer manufacturer website for information on
rotating the ’contents’ on your display.

To adjust the Rotation Display Settings:

1 Right-click on the desktop and click Properties.
2 Select the Settings tab and click Advanced.

3 If you have an ATI graphics card, select the Rotation tab and set the preferred

rotation.
4 If you have an nVidia graphics card, click the nVidia tab, in the left-hand column
select NVRotate, and then select the preferred rotation.
5 If you have an Intel® graphics card, select the Intel graphics tab, click Graphic
Properties, select the Rotation tab, and then set the preferred rotation.

NOTE: If you do not see the rotation option or it is not working correctly, go to

www.dell.com/support and download the latest driver for your graphics card.

Troubleshooting

WARNING: Before you begin any of the procedures in this section, follow 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 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 all digital and the analog 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 white. Also, depending upon the selected input, one of the
dialogs shown below will continuously scroll through the screen.

or

Troubleshooting | 43

or

4 This box also appears during normal system operation, if the video cable becomes
disconnected or damaged.
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.

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 Make sure 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.
3 Press and hold Button 1 and Button 4 on the front panel simultaneously for 2
seconds. A gray screen appears.

44 | Troubleshooting

4 Carefully inspect the screen for abnormalities.
5 Press Button 4 on the front panel again. The color of the screen changes to red.
6 Inspect the display for any abnormalities.
7 Repeat steps 5 and 6 to inspect the display in green, blue, black, white, and text
screens.
The test is complete when the text screen appears. To exit, press Button 4 again.

If you do not detect any screen abnormalities upon using the built-in diagnostic tool,
the monitor is functioning properly. Check the video card and computer.

Cleaning Your Monitor

WARNING: Before cleaning the monitor, unplug the monitor power cable from
the electrical outlet.
CAUTION: Read and follow the Safety Instructions before cleaning the monitor.

For best practices, follow these instructions in the list below while 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, soft 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.
