Maximum Length: 16' with a standard cable, Up to 50' with a high quality cable. VGA is an analog signal and so as distance increases the quality will decrease. A lot of factors can determine the maximum cable length, but for low resolutions (up to 800x600) you can reach 100 feet and beyond without too much trouble. For mid-range resolutions of 1280x1024/1024x768 you can typically reach somewhere between 50 to 100 feet.
Video Graphics Array (VGA) is the display hardware first introduced with the IBM PS/2 line of computers in 1987. Through widespread adoption, the term has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector, or the 640Ã480 resolution characteristic of the VGA hardware.
