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:  
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.
