VGA stands for Video Graphics Array. VGA was created in 1987 by IBM, and is known as the “blue cable with 15 pins and screws”, the latter being used to secure the connection. The VGA cable is the one that enters in the matching jack, making the connection between two devices.
VGA can display resolutions up to 1080p, but the major problem with this type of connection is that it uses analog signals to transmit signals to a receiver, which results in poorer image quality compared to other digital interfaces.
VGA cable ports are found on older systems. Not all recently manufactured TVs, computers, monitors and laptops have VGA ports. Also, a separate audio connector is required if you need to transmit audio signals as well, because the VGA can work only with video signals. The length of the cable and its quality play an important role when it comes to signal degradation.
Slowly, the VGA port will be removed completely from the manufacture of new devices. With this information we do not want to discourage you from using the VGA port, but if the system you have allows for connections higher than the VGA, we recommend using them for a better image quality.
