VGA – Video Graphics Array

History of VGA

VGA was developed by IBM in 1987 and is a display hardware technology that IBM first introduced with the IBM PS/2 lines of computers. And it quickly became a popular standard for displaying graphics and video on personal computers.

The VGA standard uses an analogue signal to transmit video data and supports resolutions of up to 640×480 pixels with a maximum refresh rate of 60Hz. The VGA is a 15-pin D-sub connector and it is used as connector, which is still found on older computers and some display devices.

While VGA has been largely replaced by newer digital display standards such as HDMI and DisplayPort, it remains a useful legacy standard for displaying older computers and devices that only support VGA inputs.

Features Provided by VGA

Here are some features of VGA (Video Graphics Array):

  • VGA is a display standard for computers, introduced by IBM in 1987.
  • VGA supports a resolution of 640×480 pixels with 16 colours or 320×200 pixels with 256 colours.
  • VGA has a 15-pin D-sub connector that carries analogue signals for red, green, blue, horizontal and vertical synchronization, and ground.
  • VGA has a refresh rate of 60 Hz, which means the screen is redrawn 60 times per second.
  • VGA uses a RAMDAC (Random Access Memory Digital-to-Analog Converter) to convert digital data into analogue signals for the display.
  • VGA supports both planar and packed-pixel display modes for displaying images.
  • VGA has hardware support for the smooth scrolling of images on the screen.
  • VGA does not have hardware support for sprites, which are graphical objects that can be moved independently on the screen.
  • VGA does not have a blitter, but it supports fast data transfers using VGA latch registers.
  • VGA has a barrel shifter that can shift bits in a binary number by one or more positions.
  • VGA supports split-screen display, which allows different parts of the screen to display different images.
  • VGA has a 75-ohm double-terminated impedance for the signal output.

Advantages of VGA

The following are the advantages of VGA:

  • One of the main advantages of VGA is supported by every personal computer, regardless of manufacturer.
  • Another benefit of VGA is that its signals are analogue, which offers more precision than digital ones.
  • VGA signals can be easily split using simple distribution amplifiers, making VGA a straightforward and practical option.
  • The fact that VGA only has one standard and no variants makes it simple to connect devices with VGA-out to VGA-in.
  • VGA improved the rendering and clarity of small print characters, increasing overall display quality.
  • Compared to earlier predecessors such as the Enhanced Graphics Adapter, which had a maximum resolution of 320×200 pixels, VGA was a significant improvement.
  • Finally, VGA cables can transmit a variety of analogue signals, including RGBHV, YPbPr, composite and S-Video, making them a versatile and widely usable option.

Disadvantages or Limitations of VGA

The following are the disadvantages of VGA:

  • One disadvantage of VGA is that it is an older technology with limited support for higher resolutions. And for this reason, VGA is not suitable for modern multimedia applications that require high-resolution displays and complex graphics.
  • Another disadvantage of VGA is that it has less colour capability than its successor.
  • Additionally, VGA cables may require a higher gauge to run longer, which can be a disadvantage in some setups.
