OUTLINE OF THE PRODUCT, NOMENCLATURE AND FUNCTION

1 – 2

■ 

■ 

The monitor is based on VESA DPMS (Display Power Management Sig-
naling).

To activate the monitor's power management function, both the video

card and the computer must conform to the VESA DPMS standard.

■ 

This monitor supports the VESA DDC (Display Data Channel) standard.
DDC is a signal standard for carrying out Plug & Play functions on the

monitor or PC. It transfers information such as degree of resolution

between the monitor and PC. You can use this function if your PC is DDC
compliant and if it is set so that it can detect the Plug & Play monitor.

There are many varieties of DDC due to the differences between sys-

tems. This monitor works with DDC1 and DDC2B.

■ 

Caution: Be sure to hold both sides of the monitor when adjusting the view-

ing angle. The LCD panel used in this monitor is made of glass.

Pressure from hands on the LCD panel could cause damage.
