Plug & Play DDC1/2B Feature
TECHNICAL SUPPORT(FAQ)
Power LED is not on
This monitor is equipped with VESA DDC1/2B capabilities
according to the VESA DDC STANDARD. It allows the
monitor to inform the host system of its identity and,
depending on the level of DDC used, communicate additional
information about its display capabilities. The communication
channel is defined in two levels, DDC1 and DDC2B.
The DDC1 is a unidirectional data channel from the display to
the host that continuously transmits EDID information. The
DDC2B is a bidirectional data channel based on the I²C
protocol. The host can request EDID information over the
DDC2B channel.

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.
USING THE RIGHT POWER CORD:
*Move electrical devices that may cause electrical
interference.
The power LED is ON (orange) but there’s no video or
no picture.
*Computer Power Switch should be in the ON position
*Computer Video Card should be snugly seated in its slot
*Make sure monitor’s video cable is properly connected to
the computer.
*Inspect monitor’s video cable and make sure none of the
pins are bent.
*Make sure computer is operational by hitting the CAPS
LOCK key on the keyboard while observing the CAPS
LOCK LED. The LED should either turn ON or OFF after
hitting the CAPS LOCK key.
