Video Graphics Array
open-in-new
<p>Video Graphics Array (VGA) is a <a href="/facts/Video_display_controller/ISm9E6Nc">video display controller</a> and accompanying de facto graphics standard, first introduced with the <a href="/facts/IBM_PS%2f2/G299srDC">IBM PS/2</a> line of computers in 1987, which became ubiquitous in the <a href="/facts/IBM_PC_compatible/zGUpl7Sh">IBM PC compatible</a> industry within three years. The term can now refer to the <a href="/facts/Computer_display_standard/GsjCmahB">computer display standard</a>, the 15-pin <a href="/facts/D-subminiature/ygqtB3CQ">D-subminiature</a> <a href="/facts/VGA_connector/FI7TpsL6">VGA connector</a>, or the 640 × 480 <a href="/facts/Graphics_display_resolution/zyMA9HHI">resolution</a> characteristic of the VGA hardware. </p><p>VGA was the last IBM graphics standard to which the majority of IBM PC compatible computer manufacturers conformed, making it the <a href="/facts/Lowest_common_denominator/vdf2gKmo">lowest common denominator</a> that virtually all post-1990 PC graphics hardware can be expected to implement. </p><p>VGA was adapted into many extended forms by third parties, collectively known as <a href="/facts/Super_VGA/McoGejer">Super VGA</a>, then gave way to custom <a href="/facts/Graphics_processing_unit/PTK1RQVp">graphics processing units</a> which, in addition to their proprietary interfaces and capabilities, continue to implement common VGA graphics modes and interfaces to the present day. </p><p>The VGA analog interface standard has been extended to support resolutions of up to 2048 × 1536 for general usage, with specialized applications improving it further still.[<i>specify</i>] </p>
