What is VGA, and how does it work?
VGA, or Video Graphics Array, is a standard for video output that has been widely used since its introduction in 1987. It transmits analog video signals from the source device, such as a laptop, to a display, like a monitor or projector. VGA connectors typically have 15 pins arranged in three rows, allowing the transfer of RGB (red, green, blue) color components and vertical and horizontal sync signals to create the image on the screen.
When you connect your laptop to a monitor using a VGA cable, the laptop’s graphics card converts the digital video signal into an analog format compatible with the VGA output. This process enables older monitors and projectors without digital ports to display images from more modern devices. Although VGA is gradually being replaced by digital standards like HDMI and DisplayPort, it remains a viable option for many users.
