Appendix Horizontal Frequency Characters or images displayed on the monitor screen consist of numerous dots (pixels). Pixels are transmitted in horizontal lines, which are then arranged vertically to create an image. The horizontal frequency is measured in kHz and represents how many times horizontal lines per second are transmitted and displayed on the monitor screen. A horizontal frequency of 85 means that the horizontal lines that make up an image are transmitted 85 000 times per second, and the horizontal frequency is indicated in 85kHz. Vertical Frequency One image is made of numerous horizontal lines. The vertical frequency is measured in Hz and represents how many images can be created per second by those horizontal lines. A vertical frequency of 60 means that an image is transmitted 60 times per second. The vertical frequency is also called "refresh rate" and affects screen flicker. Resolution Resolution is the number of horizontal pixels and vertical pixels that form a screen. It represents the level of display detail. A higher resolution displays a greater amount of information on the screen and is suitable for performing multiple tasks at the same time. E.g. A resolution of 1920 x 1080 consists of 1,920 horizontal pixels (horizontal frequency) and 1,080 vertical lines (vertical resolution). E.g. A resolution of 1920 x 1200 consists of 1,920 horizontal pixels (horizontal frequency) and 1,200 vertical lines (vertical resolution). Plug & Play The Plug & Play feature allows the automatic exchange of information between a monitor and PC to produce an optimum display environment. The monitor uses VESA DDC (international standard) to execute Plug & Play. 91 Appendix

Appendix
Horizontal Frequency
Characters or images displayed on the monitor screen consist of numerous dots (pixels). Pixels are
transmitted in horizontal lines, which are then arranged vertically to create an image. The horizontal
frequency is measured in kHz and represents how many times horizontal lines per second are
transmitted and displayed on the monitor screen. A horizontal frequency of 85 means that the
horizontal lines that make up an image are transmitted 85 000 times per second, and the horizontal
frequency is indicated in 85kHz.
Vertical Frequency
One image is made of numerous horizontal lines. The vertical frequency is measured in Hz and
represents how many images can be created per second by those horizontal lines. A vertical
frequency of 60 means that an image is transmitted 60 times per second. The vertical frequency is
also called "refresh rate" and affects screen flicker.
Resolution
Resolution is the number of horizontal pixels and vertical pixels that form a screen. It represents the
level of display detail.
A higher resolution displays a greater amount of information on the screen and is suitable for
performing multiple tasks at the same time.
E.g. A resolution of 1920 x 1080 consists of 1,920 horizontal pixels (horizontal frequency) and 1,080
vertical lines (vertical resolution).
E.g. A resolution of 1920 x 1200 consists of 1,920 horizontal pixels (horizontal frequency) and 1,200
vertical lines (vertical resolution).
Plug & Play
The Plug & Play feature allows the automatic exchange of information between a monitor and PC to
produce an optimum display environment.
The monitor uses VESA DDC (international standard) to execute Plug & Play.
