Terminology
480i / 480p / 720p / 1080i /
1080p____ Each of the scanning
rates above refers to the number of effective scanning lines that decides the screen resolution. The scanning rate may be indicated in i (interlaced) or p (progressive), depending on the scanning method.
- Scanning
Scanning refers to a process of sending pixels that form an image progressively. A larger number of pixels will deliver a clearer and more vivid picture.
- Progressive
In progressive scan mode, all lines of pixels are scanned one by one (progressively) on the screen.
- Interlaced
In interlaced scan mode, every other line of pixels is scanned from top to bottom first and then the remaining lines of pixels (that were not scanned) are scanned.
(progressive scan) displays a horizontal line from the top to the bottom of a screen progressively. Interlace mode displays the odd number lines first and the even number lines next.
Dot Pitch____ The 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 product
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.
Source____ Input source refers to
a video source device connected to the product such as a camcorder or video or DVD player.
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).
DVD (Digital Versatile Disc)____
DVD refers to a
HDMI (High Definition Multimedia Interface)____ It is an interface that
can be connected to a digital audio source as well as a
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.
