So they convert the analog signal from the VGA connector back to a digital signal. Nevertheless, most display devices are now digital. If the display device is an old CRT (Cathode Ray Tube) monitor, it will accept analog signals. The digital video signal received from the signal source is converted into an analog signal and transmitted through the cable. The VGA connector carries analog signals. The signal is transmitted from the source device through the port to the connector cable, and then to the destination that is the display device. When referring to DVI vs VGA, both connectors work in the same way: the device has female ports and the connector cable has male terminals.

In contrast to HDMI, neither VGA nor DVI supports audio. You can easily distinguish them because the VGA connector (and port) is blue, and the DVI connector is white. Compared with VGA, DVI is newer and provides a better and clearer display. VGA connectors and cables can transmit analog signals, while DVI can transmit analog signals and digital signals. Speaking of DVI vs VGA, the major difference between them is the picture quality and the transmission method of the video signal. VGA and DVI connectors are designed to transmit video from a source (such as a computer) to a display device (such as a monitor, TV, or projector). In this post, MiniTool will give you detailed information about DVI vs VGA. You can use both DVI and VGA connectors to transmit video from a source to a display device, but what are the differences between DVI and VGA? If you want to know, then this post is what you need.
