All Amiga systems can display full-screen animated [[Planar (computer graphics)|planar]] graphics with 2, 4, 8, 16, 32, 64 ([[Amiga Halfbrite mode|EHB Mode]]), or 4096 colors ([[Hold-And-Modify|HAM Mode]]). Models with the AGA chipset (A1200 and A4000) also have non-EHB 64, 128, 256, and 262144 ([[Hold-And-Modify|HAM8 Mode]]) color modes and a palette expanded from 4096 to [[24-bit color|16.8 million colors]].

The Amiga chipset can ''[[genlock]]'', which is the ability to adjust its own screen refresh timing to match an incoming NTSC or PAL video signal. When combined with setting transparency, this allows an Amiga to overlay an external video source with graphics. This ability made the Amiga popular for many applications, and provides the ability to do [[Character generator|character generation]] and [[Computer-generated imagery|CGI]] effects far more cheaply than earlier systems. This ability has been frequently utilized by wedding videographers, TV stations and their weather forecasting divisions (for weather graphics and radar), advertising channels, music video production, and desktop videographers. The [[NewTek]] [[Video Toaster]] was made possible by the genlock ability of the Amiga.

In 1988, the release of the Amiga A2024 fixed-frequency [[monochrome monitor]] with built-in [[framebuffer]] and [[flicker fixer]] hardware provided the Amiga with a choice of high-resolution graphic modes (1008×800 for NTSC and 1008×1024 for PAL) with 4 [[Grayscale]] levels.<ref name="AutoP5-8" /><ref>https://www.infania.net/misc/gona/Commodore/monitor/manuals/Commodore_A2024_High_Resolution_Monitor_Users_Guide.pdf</ref>
