VGA connector as it is commonly known (other names include RGB

connector, D-sub 15, mini sub D15 and mini D15) is a three-row

15 pin DE-15. There are four versions: original and DDC2

pinouts, the far older and less flexible DE-9 connector, and a

Mini-VGA used for laptops.

The common 15-pin VGA connector found on most video cards,

computer monitors, high definition televisions which support VGA

connections, and other devices, is almost universally called

"HD-15". HD stands for "high-density", which distinguishes it

from connectors having the same form factor but only 2 rows of

pins. However, this connector is often incorrectly referred to

as a DB-15 or HDB-15.

"VGA connectors" and their associated cabling are always used

solely to carry analog component RGBHV (red - green - blue -

horizontal sync - vertical sync) video signals along with DDC2

digital clock and data.

Where size is a constraint (such as laptops) a mini-VGA port can

sometimes be found in place of the full-sized VGA connector.

Super Video Graphics Array or Ultra Video Graphics Array, almost

always abbreviated to Super VGA, Ultra VGA or just SVGA or UVGA

is a broad term that covers a wide range of computer display

standards.

Originally, it was an extension to the VGA standard first

released by IBM in 1987. Unlike VGAa purely IBM-defined

standardSuper VGA was defined by the Video Electronics

Standards Association (VESA), an open consortium set up to

promote interoperability and define standards. When used as a

resolution specification, in contrast to VGA or XGA for example,

the term SVGA normally refers to a resolution of 800 × 600

pixels.

Though Super VGA cards appeared in the same year as VGA, it

wasn't until 1989 that Super VGA was defined by VESA. In that

first version, it called for a resolution of 800 × 600 4-bit

pixels. Each pixel could therefore be any of 16 different

colours. It was quickly extended to 1024 × 768 8-bit pixels,

and well beyond that in the following years.

Although the number of colours was defined in the original

specification, this soon became irrelevant as (in contrast to

the old CGA and EGA standards) the interface between the video

card and the VGA or Super VGA monitor uses simple analog

voltages to indicate the desired colour depth. In consequence,

so far as the monitor is concerned, there is no theoretical

limit to the number of different colours that can be displayed.

Note that this applies to any VGA or Super VGA monitor.

While the output of a VGA or Super VGA video card is analog, the

internal calculations the card performs in order to arrive at

these output voltages are entirely digital. To increase the

number of colours a Super VGA display system can reproduce, no

change at all is needed for the monitor, but the video card

needs to handle much larger numbers and may well need to be

redesigned from scratch. Even so, the leading graphics chip

vendors were producing parts for high-colour video cards within

just a few months of Super VGA's introduction.

On paper, the original Super VGA was to be succeeded by Super

XGA, but in practice the industry soon abandoned the attempt to

provide a unique name for each higher display standard, and

almost all display systems made between the late 1990s and the

early 2000s are classed as Super VGA.

Monitor manufacturers sometimes advertise their products as XGA

or Super XGA. In practice this means little, since all Super VGA

monitors manufactured since the later 1990s have been capable of

at least XGA and usually considerably higher performance.

SVGA uses a VGA connector, the same DE-15 (a.k.a. HD-15) as the

original standard.

cable for SVGA and other resolutions.
