Commodore Amiga CD32 Standard Interlaced Display Resolution

This article provides a definitive answer regarding the pixel dimensions of the Commodore Amiga CD32 when operating in its standard interlaced display mode. It explores the technical specifications of the AGA chipset, distinguishes between regional video standards such as PAL and NTSC, and clarifies the vertical resolution doubling effect inherent to interlaced scanning on this classic gaming console.

The Commodore Amiga CD32 utilizes the Advanced Graphics Architecture (AGA) chipset, which supports various display modes depending on the region and software requirements. For the standard interlaced display mode, the horizontal resolution typically remains at 320 pixels, while the vertical resolution is doubled compared to the non-interlaced standard. In PAL regions, where the CD32 was most widely released, the standard interlaced resolution is 320x512 pixels. In NTSC regions, the corresponding standard interlaced resolution is 320x400 pixels.

Interlaced mode works by drawing every other line in one pass and the remaining lines in the second pass, effectively doubling the vertical detail without requiring additional horizontal bandwidth. While the hardware is capable of high-resolution interlaced modes such as 640x512 pixels in PAL, the 320-pixel width is considered the standard for most CD32 games to ensure smooth scrolling and performance. Understanding these distinctions is crucial for enthusiasts configuring retro displays or emulators to achieve authentic visual fidelity.
