 VGA was the last IBM graphics standard to which the majority of PC clone manufacturers conformed, making it the lowest common denominator that virtually all post-1990 PC graphics hardware can be expected to implement.It was officially followed by IBM's Extended Graphics Array (XGA) standard but instead was effectively superseded by numerous slightly different extensions to VGA made by clone manufacturers, collectively known as Super VGA.Today, the VGA analog interface is used for high-definition video, including resolutions of 1080p and higher.
