Terminology

Dot Pitch
The monitor and screen consist of red, green and blue dots. A shorter distance between the dots
produces a higher resolution. Dot pitch refers to the distance between the shortest distance between
dots of the same color. Dot pitch is measured in millimeters.
Vertical Frequency
The monitor displays a single image many times per second (like a fluorescent light that flickers) to
display an image for a viewer to see. The rate of a single image being displayed repeatedly per second
is called vertical frequency or refresh rate. Vertical frequency is measured in Hz.
E.g. 60Hz refers to a single image being displayed 60 times in one second.
Horizontal Frequency
The time required to scan a single line from the left to the right side of the screen is called a horizontal
cycle. The reciprocal number of a horizontal cycle is called horizontal frequency. Horizontal frequency
is measured in kHz.
Plug & Play
Plug & Play is a function that allows the automatic exchange of information between a monitor and PC
to produce an optimum display environment. The product uses VESA DDC (international standard) to
execute Plug & Play.
Resolution
Resolution is the number of horizontal dots (pixels) and vertical dots (pixels) that form a screen. It
represents the level of display detail. A higher resolution enables more data to be displayed on the
screen and is useful to perform multiple tasks simultaneously.
E.g. A resolution of 1920 X 1080 consists of 1,920 horizontal pixels (horizontal resolution) and 1,080
vertical pixels (vertical resolution).
Multiple Display Control (MDC)
MDC (Multiple Display Control) is an application that allows multiple display devices to be controlled
simultaneously using a PC. Communication between a PC and monitor takes place using RS232C
(serial data transmission) and RJ45 (LAN) cables.
DVD(Digital Versatile Disc)
DVD refers to a CD-sized mass storage disk where you can save multimedia (audio, video or game)
applications using MPEG-2 video compression technology.
