A computer system is not just the traditional setup of monitor, keyboard, sound system, and mouse anymore. We connect that one monitor to a projector, an additional monitor, or another type of visual output device. Bluetooth has made it easy to connect all these wirelessly. Should we need wired connections, which may prove to be more secure in that they maintain the connection without disruptions, there are specific types of cables whose main purpose is to transmit video.
The two main types of connectors are DVI and VGA. Let’s delve into them more. DVI Connector DVI stands for Digital Visual Interface. DVIs are considered distinctive because they can carry both digital and analog signals and give a sharp picture quality. These connectors are relatively newer and usually come in white or gray. A big advantage of DVI connectors is that they can be plugged into your source device without the hassle of shutting it down. Just plug it in while the source device is in use, and the display flow should be seamless. These connections are typically wide and consist of twenty-nine or twenty-five pins. DVI cables are available in three types, each with its own function:
VGA Connector VGA stands for Video Graphics Array. Unlike the DVI connectors, which transmit both analog and digital signals, the VGA cable only transfer analog signals, making this technology old-school. Created and distributed by IBM in 1987, it was primarily used for computer monitors and TV sets. VGA connectors consist of fifteen pins with three rows of five pins each. Every one of these pins has a unique function. The first row of these pins transfers the color red, the second row transfers green, and the last row transfers the color blue. If we were to compare these two connectors on the basis of release dates, the DVI would be the new kid on the block, having come out in 1991. As mentioned earlier, VGA came out in 1987. Now, let’s see which is better, DVI or VGA. To more about Difference Between DVI and VGA click on below button.
