Power management modes  
If you have VESA's DPM 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 the computer detects input from  
the 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.  
* Zero power consumption in off mode can only be achieved by disconnecting the  
power cable from the monitor.

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 the system 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 your 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 Dell Monitor  
Quality and Pixel Policy, see Dell Support site at www.dell.com/support/

monitor.  
For best practices, follow the instructions in the list below while unpacking, cleaning

static coating. Do not use benzene, thinner, ammonia, abrasive cleaners or  
compressed air.

follow the Safety Instructions.  
Self-Test  
Your monitor provides a self-test feature that allows you to check if 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:  
Turn off both your computer and the monitor.  
1.  
Disconnect all video cables from the monitor. This way, the computer doesn’t  
have to be involved.  
2.  
Turn on the monitor.  
3.  
If the monitor is working correctly, it detects that there is no signal and one of the  
following message appears. While in self-test mode, the power LED remains white.
