About this deal

Some pins on the connector were also different: pin 9 was keyed by plugging the female connector hole, and four pins carried the monitor ID. [6] Shah, Agam (31 July 2012). "VGA ports bowing out of home computers, lingering in the workplace". Computerworld . Retrieved 16 August 2020.

VGA connector - Wikipedia

A VGA extender is an electronic device that increases the signal strength from a VGA port, most often from a computer. They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have minor artifacts if the cable runs too far without an extender). VGA extenders are sometimes called VGA boosters. The VGA connector is a three-row, 15-pin D-subminiature connector referred to variously as DE-15, [2] HD-15 [4] or erroneously DB-15(HD). DE-15 is the accurate nomenclature under the D-sub specifications: an "E" size D-sub connector, with 15 pins in three rows.a b "Video Subsystem (Type 1)".

Whether you want to build your own home theater or just learn more about TVs, displays, projectors, and more, we've got you covered. The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 320×400px @70Hz, or 320×480px @60Hz (12.6MHz of signal bandwidth) to 1280×1024px ( SXGA) @85Hz (160MHz) and up to 2048×1536px ( QXGA) @85Hz (388MHz).

The terminology here is sometimes used rather interchangeably when it comes to labelling various types of VGA cable and can be a little vague. However, the basic or standard VGA connector type will usually be referred to as some variant of the following: DE-15, HD15, VGA plug, SVGA plug, D-Sub 15 or D-Subminiature, or the more generic RGB connector.

Retrieved 16 February 2021. Some laptops and other portable devices in the early to mid-2000s contained a two-row mini-VGA connector that is much smaller than the three-row DE-15 connector, as well as five separate BNC connectors.

A correctly impedance matched cable (75 ohm) should prevent this, however, ghosting with long cables may be caused by equipment with incorrect signal termination or by passive cable splitters rather than the cables themselves.

What Is VGA? (Definition of Video Graphics Array) - Lifewire

The Video Graphics Array ( VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [1] as well as many monitors, projectors and high-definition television sets. For conversions to and from digital formats like HDMI or Displayport, a scan converter is required. VGA outputs to interfaces with different signaling, more complex converters may be used. Most of them need an external power source to operate and are inherently lossy. However, many modern displays are still made with multiple inputs including VGA, in which case adapters are not necessary.

The image and table detail the 15-pin VESA DDC2/E-DDC connector; the diagram's pin numbering is that of a female connector functioning as the graphics adapter output. In the male connector, this pin numbering corresponds with the cable's wire-and-solder side.

VESA Enhanced Display Data Channel Standard Version 1.1. Video Electronics Standards Association. 24 March 2004. p.18. All VGA connectors carry analog RGBHV (red, green, blue, horizontal sync, vertical sync) video signals. Modern connectors also include VESA DDC pins, for identifying attached display devices. With the implementation of the VESA DDC specification, several of the monitor ID pins were reassigned for use by DDC signaling, and the key pin was replaced with a +5V DC output per the DDC spec. Devices that comply with the DDC host system standard provide 5 V ± 5%, from 50 mA to 1 A. [7] PS/55 signaling [ edit ]This article needs additional citations for verification.

Some high-end monitors and video cards used multiple BNC connectors instead of a single standard VGA connector, [ which?] providing a higher quality connection with less crosstalk [10] by utilising five separate 75 ohm coaxial cables. While shorter VGA cables are less likely to introduce significant signal degradation, good-quality cable should not suffer from signal crosstalk (whereby signals in one wire induce unwanted currents in adjacent wires) even at greater lengths.
