tance between two dots of the same color is called the 'Dot

 

Pitch'. Unit: mm

Vertical Frequency

The screen must be redrawn several times per second in

 

order to create and display an image for the user. The fre-

 

quency of this repetition per second is called the Vertical

 

Frequency or Refresh Rate. Unit: Hz

 

Example: If the same light repeats itself 60 times per sec-

 

ond, this is regarded as 60 Hz.

Horizontal Frequency

The time to scan one line connecting the right edge to the

 

left edge of the screen horizontally is called the Horizontal

 

Cycle. The inverse number of the Horizontal Cycle is called

 

Horizontal Frequency. Unit: kHz

Interlace and Non-Interlace

Showing the horizontal lines of the screen from the top to

Methods

the bottom sequentially is called the Non-Interlace method

 

while showing odd lines and then even lines in turn is called

 

the Interlace method. The Non-Interlace method is used for

 

the majority of monitors to ensure a clear image. The Inter-

 

lace method is the same as that used in TVs.

Plug & Play

This is a function that provides the best quality screen for

 

the user by allowing the computer and the monitor to ex-

 

change information automatically. This monitor follows the

 

international standard VESA DDC for the Plug & Play func-

 

tion.

Resolution

The number of horizontal and vertical dots used to compose

 

the screen image is called the 'resolution'. This number

 

shows the accuracy of the display. A high resolution is good

 

for performing multiple tasks as more image information can

 

be shown on the screen.

 

Example: If the resolution is 1920 x 1080, this means the

 

screen is composed of 1920 horizontal dots (horizontal res-

 

olution) and 1080 vertical lines (vertical resolution).
