Brief Description
VGA is a popular display standard, stands for Video Graphics Array. It was first proposed by IBM in 1987. It’s a three row 15 pin connector comes with a screw type locking mechanism. A VGA cable carries analog components RGBHV video signal (Red, Green, Blue, Horizontal sync, Vertical Sync) and DDC data. Due to VGA carries analog signal we may suffer signal loss if we increase the wire length. The maximum resolution that a VGA can provide is 2048 x 1536 pixels. The disadvantage of a VGA is it doesn’t carry audio signal.
Applications
VGA connectors are used to connect the Computer or Laptops (which have VGA connector) to a TV, Monitor or Projector.
