Which connector is known as a legacy analog video interface?

VGA, which stands for Video Graphics Array, is recognized as a legacy analog video interface. It was first introduced in 1987 and was widely used for connecting computers to monitors for many years. The VGA connector transmits video signals in an analog format, which differentiates it from modern interfaces that typically use digital signals.

Its design supports resolutions up to 640x480, and while it can support higher resolutions through various configurations, the quality degrades as the distance increases and when subjected to interference. VGA is notable for its 15-pin connector that provides a standard interface for video output.

In contrast, other options such as HDMI, DVI, and DisplayPort are all digital video interfaces. They provide better video quality, support higher resolutions, and offer digital audio transmission, which is not achievable with VGA. Therefore, VGA stands out as a legacy product in today's landscape dominated by digital technologies.
