What is a VGA cable, and how does it work?
A VGA (Video Graphics Array) cable is an older type of video connection typically used to connect computers to monitors or projectors. It carries analog video signals, which means it can transmit a visual image without the audio component. VGA connectors have 15 pins in three rows, which send color data from the computer’s graphics card to the display.
Although VGA cables are less common today due to the rise of digital connectors like HDMI and DisplayPort, they are still widely used in older equipment. The signals transmitted through a VGA cable can support various resolutions, but they are prone to degradation over longer cable lengths or if the connections are not secure.
Can I use two monitors with a single VGA port?
Yes, you can use two monitors with a single VGA port, but it typically requires a VGA splitter. A VGA splitter allows you to duplicate the display output from your computer’s single VGA port to two monitors simultaneously. This setup is great for presentations or similar applications where the same content is displayed on both screens.
However, it’s essential to note that using a splitter will mirror the display, not extend it, meaning both monitors will show the same image rather than functioning as separate screens. If you require an extended display setup, additional ports (like HDMI or DisplayPort) or a dedicated graphics card with multiple outputs would be necessary.
