ENGLISH

DDC (Display Data Channel)

DDC is a communication channel over which the monitor automatically informs the host system (PC) about its capabilities.

DDC protocol

① DDC1/DDC2B
An uni-directional communication channel.
② DDC 2AB/DDC2B+/DDC2Bi
A bi-directional communication channel.

Note

- PC must support DDC functions to do this.

E-DDC (Enhanced DDC)

A protocol based on I²C and used on a bidirectional data channel between the display and host. This protocol accesses devices at I²C address of A0/A1 as well as the address 60. The 60 address is used as a segment register to allow larger amounts of data to be retrieved than is possible using DDC2B protocols. The protocol is compatible with DDC2B protocols.

Energy Saving Design

This program is designed to have computer equipment manufacturers build circuitry into their products to reduce power consumption when it is not in operation.

When this monitor is used with a PC on which a screen blanking software complying with the VESA Display Power Management Signalling (DPMS) Protocol is installed, it can conserve significant energy by reducing power consumption when it is not in operation.

There are 2 signal lines, 3 modes of operation.

: On Mode, Sleep Mode, Off Mode.

Mode Definition
On mode	The normal operation.When the monitor is on mode, being connected to a power source, it displays an image.
Sleep Mode	The reduced power state returns to on mode when the user moves the mouse or presses a key on the keyboard.
Off Mode	The lowest power consumption state returns to on mode when the user pushes a power switch.

Note

- The energy saving Design monitors only work while connected to the computers that have energy saving features.

Programa de economia de energia

Mode activé (On), mode de veille (Sleep), mode désactivé (Off).

Unplug the monitor from the wall outlet and refer servicing to qualified service personnel when :

• The power cord or plug is damaged or frayed.
  • Liquid has been spilled into the monitor.
• The monitor has been exposed to rain or water.
• The monitor does not operate normally following the operating instructions. Adjust only those controls that are covered in the operating instructions. An improper adjustment of other controls may result in damage and often requires extensive work by a qualified technician to restore the monitor to normal operation.
• The monitor has been dropped or the cabinet has been damaged.
• The monitor exhibits a distinct change in performance.
• Snapping or popping from the monitor is continuous or frequent while the monitor is operating. It is normal for some monitors to make occasional sounds when being turned on or off, or when changing video modes.

Do not attempt to service the monitor yourself, as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
