(Note: HDMI does not transmit audio signals to DVI adapters. This hardware allowed computer monitors to display a true-color pallette. You will need separate audio cables.)ĭVI was designed by Digital Display Working Group in 1999, in attempts to replace the date technology of the VGA. (Note: HDMI does not transmit audio signals to VGA adapters. VGA is today’s basic standard for color resolution in computer monitors, and represents the lowest common denominator for compatibility. VGA allows for the display of 256 colors on computer monitors, uses RGB color (Red, Green, and Blue), and is always shaped like a trapezoid. The most common is Super VGA (SVGA), which allows for resolutions greater than 640x480, such as 800 x 600 or 1024 x 768. The VGA standard originally allowed for a display resolution of 640 x 480 pixels, but has gone through many revisions since being introduced. If you guessed that the newest connectors have the best picture quality and fastest speeds, you’d be right! Let’s take a look why. VGA is equipped with 15 pins, HDMI with 19 pins, and DVI with 29 pins. The number of pins per each connector varies. HDMI (digital) was developed in December 2002, and produced from 2003 to present day. That’s where cable connectors come into play.Ĭable connectors The oldest VGA (analog) hardware was developed in 1987 and produced from 1987 to present day, followed by DVI (analog), which was developed in 1999 and produced from 1999 to present day. Over the years, technology has allowed for better and better ways of transmitting visual images to your computer monitor. In the early days of computers, monitors were originally monochrome or two-color. Known as “cable connectors,” these fellas are responsible for the transfer of digital video content, and all operate differently.ĭVI stands for Digital Visual Interface,HDMI stands for High Definition Multimedia Interface and VGA stands for Video Graphics Array. These abbreviations may not sound like household names, but chances are you’re likely to spot them in most homes.
