What is a VGA Connector?

VGA (Video Graphics Array/ Video Graphics Adapter) connector is one kind of computer port, used to connect the peripheral devices for transferring video signals as an output. It is a very famous standard display invented by IBM & launched in the year 1987.

Video Graphics Array connector provides color display screens with 640 x 480 resolution, 60 Hz refresh rate & 16 colors exhibited at a time. If the screen resolution is reduced to 320 x 200 pixels, then 256 colors will be displayed. VGA uses analog signals for fewer resolutions & less quality display over screens.
