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:

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". Wh en 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 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  
Dell™ S2240M/S2340M monitor  
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 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 both Digital (white connector) and 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 white. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll  
through the screen.

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

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:
