Dot Pitch
The image on a monitor is composed of red, green and blue dots. The closer the dots, the
higher the resolution. The distance 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 frequency 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 second, 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 Methods
Showing the horizontal lines of the screen from the top to 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 Interlace 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 exchange information automatically. This monitor follows the international
standard VESA DDC for the Plug & Play function.
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 1600 x 1200 , this means the screen is composed of 1600
horizontal dots (horizontal resolution) and 1200 vertical lines (vertical resolution).
For Better Display

Vertical frequency (refresh rate): 60 Hz
2. TFT LCD panel manufactured by using advanced semiconductor technology with precision of
1ppm (one millionth) above is used for this product. But the pixels of RED, GREEN, BLUE
and WHITE color seem to be bright sometimes or some of black pixels could be seen.
This is not from bad quality and you can use it without uneasiness.
{
For example, the number of TFT LCD sub pixels that is contained in this product are
