SVGA (Super Video Graphics Array), introduced c. 1990, is not a firmly outlined standard
. The features of each SVGA board are decided only by the manufacturer.
However, all video cards bearing the SVGA label have two things in common:
- They must have full VGA support.
- They must support screen modes beyond those in the VGA standard, i.e. above 640x480x16.
Since there is no standard defining
what an SVGA card must include, drivers
must be loaded to enable the card to function at screen modes not included in the VGA standard. In the beginning, the only option for was to use proprietary
drivers, but an effort has been made to provide a standard, universal
driver, called VBE
, the VESA Bios
Extension. Most modern video cards support VBE, which is now in version 3.0, eliminating the need to load specific drivers for SVGA screen modes. However, to get the full performance
out of a card, it is often better to use the most recent version of the manufacturer's drivers.
SVGA cards connect to a monitor through a 15-pin D-type connector. The pinout
is the same as a standard VGA
card, but is listed here as well, in the interest of completeness
