Video Graphics Array

Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987, but through its widespread adoption has also come to mean either an Amplitude Modulated computer display standard, the 15-pin D-subminiature VGA connector or the 640x480 resolution itself.

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 It was officially followed by IBM's Extended Graphics Array (XGA) standard, but was effectively superseded by numerous slightly different extensions to VGA made by clone manufacturers, collectively known as Super VGA.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. While the transmission bandwidth of VGA is high enough to support even higher resolution playback, there can be picture quality degradation depending on cable quality and length. How discernible this degradation is depends on the individual's eyesight and the display, though it is more noticeable when switching to and from digital inputs like HDMI or DVI.

Graphics display resolution

The graphics display resolution is the width and height dimensions of an electronic visual display device, such as a computer monitor, in pixels. Certain combinations of width and height are standardized and typically given a name and an initialism that is descriptive of its dimensions. A higher display resolution in a display of the same size means that displayed content appears sharper.

Overview by vertical resolution and aspect ratio

Aspect ratio

The favoured aspect ratio of mass market display industry products has changed gradually from 4:3, then to 16:10, and then to 16:9, and now 21:9. This has made many of the display resolutions listed in this article difficult to obtain in mass market products. The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT). The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 aspect ratio tends to reflect post-2010 mass market computer monitor, laptop, and entertainment products displays. In many cases the resolutions listed in the sections below may have a small market, may only be seen in specialized industrial or computer market products, or may not be available for sale.
