Power Management Modes
If you have VESA's DPMS compliant display card or software installed in your PC, the display can
automatically reduce its power consumption when not in use. If input from keyboard,
mouse or other input devices is detected, the display will automatically
"wake up". The following table shows the power consumption and
signaling of this automatic power saving feature:

is less than 120V (all other power <=3W).
Zero power consumption in OFF mode can only be achieved by
disconnecting the mains cable from the display.

Plug and Play
Capability
You can install the
display in any Plug and Play-compatible system. The display 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 display settings. If desired, the user can select
different settings, but in most cases display installation is automatic.
Cleaning 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. |
- 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.
