The Amiga 520 adapter allowed for RF modulated and composite video output, to be connected to a TV

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 30 kHz HSync for standard Amiga video modes. This is not compatible with most VGA monitors but usually with most Televisions. 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.
