The Amiga video connector is used on all Commodore Amiga computers. The 23-pin D-subminiature has signals for genlocking, 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 RF modulator connects to the video port and outputs composite video and RF video.
