Power Management Modes  
If you have VESA's DPMS™ compliance display card or software installed in your PC, the monitor can automatically reduce its power consumption when not in  
use. This is referred to as Power Save Mode. If input from a keyboard, mouse or other input devices is detected by the computer, the monitor will automatically  
"wake up". The following table shows the power consumption and signaling of this automatic power-saving feature:

Plug and Play Capability  
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 that the system can configure itself and optimize the monitor settings. If required,  
the user can select different settings, but in most cases monitor installation is automatic.  
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: support.dell.com.  
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 from the electrical  
outlet.  
For best practices, follow the instructions in the list below while unpacking, cleaning, or handling your monitor:  
l
To clean your antistatic screen, lightly 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 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 a white powder when you unpack your monitor, wipe it off with a cloth.  
Handle your monitor with care as dark-colored monitors may scratch and show white scuff marks more than lighter-colored monitors.  
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.

Solving Problems  
Dell™ SR2320L monitor User's Guide  
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. To ensure proper Self-Test operation, remove the Analog (blue connector) cable 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, the dialog shown below will continuously scroll through the screen.  
or  
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 15 minutes if left at this state.  
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 have performed Step 5, check your video controller and computer system.  
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.  
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.  
3. On the front panel, press and hold the shortcut button 1 and shortcut button 4 keys on the front panel, simultaneously for 2 seconds. A gray screen  
appears.  
     
4. Carefully inspect the screen for abnormalities.  
5. Press the shortcut button 4 key 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 and white colored screens.  
The test is complete when the white screen appears. To exit, press the shortcut 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.
