Description
VESA high refresh video signal timings
This monitor supports a wide range of display modes, including a selection of the VESA timings
of incoming video signals at up to 76 Hz (non-interlaced) for the following screen resolutions:
•
640 x 480
•
720 x 400
•
800 x 600
•
1024 x 768
•
1280 x 1024
Appropriate video adapter hardware and software must be installed in the attaching system unit.
Monitors are compatible with popular Lenovo PC system units.
VESA Display Data Channel (DDC)
This monitor supports the DDC protocol to command interface (CI) level. Basic configuration
information can be passed to a system unit from its attached monitor. Often referred to as Plug
and Play, the protocol enables a DDC-enabled system unit to automatically configure the video
adapter to drive the attached monitor at its optimum display mode without end-user intervention.
For best use, the attaching system unit must also be hardware- and software-enabled for DDC
operation.
The capabilities of the monitor are held in nonvolatile monitor memory in an encoded format. The
data is received from the monitor by the system unit during boot-up and system configuration.
The EDID data sent by the monitor to the attached system unit also includes the monitor's serial
number and other identification information. This can be held in the system unit until requested;
for example, by a department LAN administrator needing to assess the location of all equipment
connected to the LAN.
Date information transmitted in the monitor EDID data conforms to VESA EDID standard V2.
This requires the year of manufacture (YOM) to be stored in a one-byte field as an offset from
1990 as derived from the following equation:
Value stored = (YOM — 1990)

An international industrial standard by the name of DDC/CI was developed by VESA to expand
upon an existing DDC standard. This new standard adds control functionality without the need
for additional connections.
The main advantage of DDC/CI is its bi-directional communication structure between PC and
monitor, which does not require a separate cable. All data are transmitted in both directions via
the video graphics card and the standard VGA or DVI signal cable. This capability allows for
functions like monitor control, adjustments, and diagnostics to be conducted via software using
