When used as shorthand for a resolution, as VGA andXGAoften are, SVGA refers to a resolution of 800 × 600.[2]
History
edit
In the late 1980s, after the release ofIBM'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.[1]The first cards that explicitly used the term wereGenoa Systems's SuperVGA and SuperVGA HiRes in 1987.[3]
Super VGA cards broke compatibility with the IBM VGA standard, requiring software developers to provide specificdisplay driversand 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 motivatedVESAto produce a unifying standard, theVESA BIOS Extensions(VBE), first introduced in 1989,[4]to provide a common software interface to all cards implementing the VBE specification.[5]
Eventually, Super VGA graphics adapters supported innumerable modes.
Specifications
edit
The Super VGA standardized the following resolutions:[4]
- 640 × 400or640 × 480with 256 colors
- 800 × 600with24-bit color depth
- 1024 × 768with 24-bit color depth
- 1280 × 1024with 24-bit color depth
SVGA uses the same DE-15VGA connectoras the original standard, and otherwise operates over the same cabling and interfaces as VGA.
