PLUG AND PLAY ( Plug & Play DDC2B Feature)
This monitor is equipped with VESA DDC2B capabilities according to the
VESA DDC STANDARD. It allows the monitor to inform the computer or
host system of its identity and, depending on the level of DDC used,
communicate additional information about its display capabilities. The
DDC2B is a bidirectional data channel based on the protocol. The host can
request EDID information over the DDC2B channel.
If your computer, video card, and operating system support DDC2B, your
monitor should automatically be set to it's optimal configuration. Some
computer systems may not have the capability to properly detect this
information. In addition, some computer systems will require manually
configuring the video options. In most cases, software and/or driver updates
will correct this issue. Please contact your computer or video card
manufacturer for more details.
THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF
THERE IS NO VIDEO INPUT SIGNAL. IN ORDER FOR THIS
MONITOR TO OPERATE PROPERLY, THERE MUST BE A
VIDEO INPUT SIGNAL.
The monitor detects the input source automatically if only one of the D-SUB
or HDMI/DVI-D ports is in use. In dual input mode (when both ports are in
use), the monitor automaticaly selects the D-SUB source for the settings.
This monitor meets the Green monitor standards as set by the Video
Electronics Standards Association (VESA) and/or the United States
Environmental Protection Agency (EPA) and The Swedish Confederation
Employees (NUTEK). This feature is designed to conserve electrical energy
by reducing power consumption when there is no video-input signal present.
When there is no video input signal this monitor, following a time-out period,
will automatically switch to an OFF mode. This reduces the monitor's
internal power supply consumption. After the video input signal is restored,
full power is restored and the display is automatically redrawn. The
appearance is similar to a "Screen Saver" feature except the display is
completely off. The display is restored by pressing a key on the keyboard, or
clicking the mouse.
