What is a VGA cable, and how does it work?
A VGA (Video Graphics Array) cable is an analog video connector used to transmit visual signals from a source device, like a laptop, to a display, such as a television or monitor. Originating in the 1980s, VGA has become a standard port found on many computers, projectors, and TVs, allowing for a reliable connection. It uses a 15-pin connector and can carry resolutions up to 640×480 pixels, although higher resolutions can also be supported depending on the device.
The VGA cable operates by sending separate signals for red, green, and blue channels, allowing for the formation of images on the screen. Because it is analog, the quality of the transmission may degrade over long distances or due to interference. Despite the rise of digital connection alternatives like HDMI, VGA is still commonly used for various applications, particularly with legacy devices.
