Full Form of VGA

The full form of VGA is “Video Graphics Array”. It is display hardware developed by IBM in 1987. It was first introduced with the IBM PS/2 line of computers. It provides a resolution of 640×480 pixels and a refresh rate of 60 Hz. VGA is referred to as an array instead of an adopter because it was implemented from the start as a single chip (ASIC). VGA uses analog signals rather than digital signals. Know more here.

Technical Specifications of VGA

In this article, we have discussed the full form of VGA and here we are going to see some technical specifications of VGA. The original VGA has the following specification:
  • 256 kB Video RAM
  • 16-color and 256-color paletted display modes.
  • 262,144-color global palette (6 bits, and therefore 64 possible levels, for each of the red, green, and
  • Maximum of 800 horizontal pixels
  • Maximum of 600 lines
  • Barrel shifter
  • Split screen support
  • 0.7 V peak-to-peak
  • 75-ohm double-terminated impedance (18.7 mA, 13 mW)
  • Refresh rates at up to 70 Hz
  • Vertical blank interrupt
  • Planar mode: up to 16 colors (4-bit planes)
  • Packed-pixel mode: 256 colors (Mode 13h)
  • Hardware smooth scrolling support
  • blue channels via the RAMDAC)
  • Selectable 25.175 MHz or 28.322 MHz master pixel clock
  • The usual line rate is fixed at 31.469 kHz
  • No hardware sprites,
  • No Blitter, but supports very fast data transfers via “VGA latch” registers.

Shape and Size of VGA

Till now we have covered the full form of VGA and some technical specifications of VGA. A VGA connector is shaped like a trapezoid and it has 15 pins. If you have an old monitor designed for the older standards may not be able to work with Video Graphics Array standards. Full form of VGA is detailed here.


The older VGAs provide a resolution of 640×480 pixels. Know the full form of VGA here. After that version, many revisions have been introduced. The most common version of VGA is Super VGA (SVGA). It allows for resolutions greater than 640×480, such as 800×600 or 1024×768.

What is VGA used for?

A video graphics array (VGA) cable is a type of computer cable that carries visual display data from the CPU to the monitor.

Which cable is best for the monitor?

USB-C connectors also output video over the DisplayPort standard, which makes it easy to output video from a laptop or Android phone with an adapter to the typical DP plug (or HDMI). Know about the full form of VGA.

What is the color of the VGA port?

VGA provides 640 x 480 resolution color display screens with a refresh rate of 60 Hz and 16 colors displayed at a time. If the resolution is lowered to 320 x 200, 256 colors are shown.

Is VGA good for gaming?

We recommend using DVI since VGA does not work very well at higher resolution. It starts to get blurry at 1920*1080. DVI does not have this issue.

How many wires are in a VGA cable?

A traditional VGA cable was fairly simple. It consisted of 14 or 15 28 AWG (28 gauge) wires in a jacket, with 15 pin connectors on either end.
