'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. The first cards that explicitly used the term were Genoa Systems's SuperVGA and SuperVGA HiRes in 1987. 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

to produce a unifying standard, the VESA BIOS Extensions (VBE), first introduced in 1989, to provide a common software interface to all cards implementing the VBE specification. Eventually, Super VGA graphics adapters supported innumerable modes.

Specifications

The Super VGA standardized the following resolutions: * 640 × 400 or 640 × 480 with 256 colors * 800 × 600 with 24-bit color depth * 1024 × 768 with 24-bit color depth * 1280 × 1024 with 24-bit color depth SVGA uses the same DE-15 VGA connector as the original standard, and otherwise operates over the same cabling and interfaces as VGA.
