The
following sections give you information about the various power management modes
and pin assignments for various connectors for your monitor.
If you have VESA's
DPMS 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 input from 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:

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. If required, the user can select different
settings, but in most cases monitor installation is automatic.

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.
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.
|
|
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 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 darker-colored plastics may scratch and show white scuff marks
more than lighter-colored monitor.
