Terms
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 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 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 in order 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
resolution. This number shows the accuracy of the display. High resolution is good for
performing multiple tasks as more image information can be shown on the screen.
Example: If the resolution is 1280 x 1024 , this means the screen is composed of 1280
horizontal dots (horizontal resolution) and 1024 vertical lines (vertical resolution).
For Better Display
1. Adjust computer resolution and screen injection rate (refresh rate) oncomputer as described
below to enjoy the best quality of picture. You can have an uneven quality of picture in the
screen if the best quality of picture is not provided in TFT-LCD.
{Resolution: 1280 x 1024 {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
3,932,160.
3. When you clean the monitor and the panel outside, please apply the recommended small
amount of cleaner by using soft and dry cloth and polish it. Let LCD area not to be forced but
to be scrubbed out softly.
If excessive force is applied, you can have a stain on it.
4. If you are not satisfied with the quality of picture, you can get better quality of picture by
executing auto adjustment function in display screen that is appeared as window
termination button is pressed.
If theres still noise after automatic adjustment, use FINE/COARSE adjustment function.
5. If you view a fixed screen for an extended period of time, residual image or blurriness may
appear.
Change the mode to energy save or set a screensaver to moving picture when you need to
be away from the monitor for an extended period of time.
