What is a VGA cable, and how does it work?
A VGA (Video Graphics Array) cable is a type of connection used for transmitting video signals from a device, such as a PC, to a display device like a monitor or a laptop screen. It carries analog video signals and typically features a 15-pin D-subminiature connector. While it may not provide the high-definition quality of newer digital connections, VGA is still a common method for connecting older devices and works well for standard resolutions.
The VGA cable relies on three main color signals: red, green, and blue (RGB), along with horizontal and vertical sync signals to ensure the image is displayed correctly. When you connect a VGA cable between your PC and a laptop, the graphics card in your PC sends the video output to the laptop screen, allowing you to utilize the laptop as an external monitor.
