History

In the late 1980s, after the release of IBM's VGA, third-party manufacturers began making graphics cards based on its specifications with extended capabilities. As these cards grew in popularity they began to be referred to as "Super VGA." This term was not an official standard, but a shorthand for enhanced VGA cards which had become common by 1988. One card that explicitly used the term was Genoa's SuperVGA HiRes. Super VGA cards broke compatibility with the IBM VGA standard, requiring software developers to provide specific display drivers and implementations for each card their software could operate on. Initially, the heavy restrictions this placed on software developers slowed the uptake of Super VGA cards, which motivated

(VBE), first introduced in 1989, to provide a common software interface to all cards implementing the VBE specification. Eventually, graphics adapters under the Super VGA umbrella would support an innumerable quantity of modes.

Specifications

The VBE standardized the following resolutions: * 800 × 600 with 4- and 8-bit color depth * 1024 × 768 with 4- and 8-bit color depth * 1280 × 1024 with 4- and 8-bit color depth SVGA uses the same DE-15
