Amiga video connector
Encyclopedia
The Amiga video connector is used on all Commodore Amiga computers. The DB23
has signals for genlock
ing, RGB analog video
(4096 colours), and a digital Red-Green-Blue-Intensity signal (16 colours).
The refresh frequency is 15 or 75 kHz
HSync
for standard Amiga video modes. This is not compatible with most VGA
monitors. A Multisync monitor
is required for some higher resolutions.
The Commodore A520 connects to the video port and outputs composite video
and RF video
.
D-subminiature
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smaller connectors used on computer systems....
has signals for genlock
Genlock
Genlock is a common technique where the video output of one source, or a specific reference signal from a signal generator, is used to synchronize other television picture sources together. The aim in video and digital audio applications is to ensure the coincidence of signals in time at a...

Hertz
The hertz is the SI unit of frequency defined as the number of cycles per second of a periodic phenomenon. One of its most common uses is the description of the sine wave, particularly those used in radio and audio applications....

Synchronization
Synchronization is timekeeping which requires the coordination of events to operate a system in unison. The familiar conductor of an orchestra serves to keep the orchestra in time....

Video Graphics Array
Video Graphics Array refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987, but through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640×480 resolution...

Multisync monitor
A multisync monitor is a monitor that can properly synchronise with various horizontal and vertical scan frequencies. In contrast, fixed frequency monitors can only synchronise with a specific horizontal and vertical frequency, limiting their flexibility...

Composite video
Composite video is the format of an analog television signal before it is combined with a sound signal and modulated onto an RF carrier. In contrast to component video it contains all required video information, including colors in a single line-level signal...
