A VGA port (Video Graphics Array port) on a laptop is a connector used to transmit video signals to external displays such as monitors, projectors, or TVs. It’s an older type of video connection that transmits analog signals, unlike newer digital connections like HDMI or DisplayPort.
Key features of a VGA port:
- Blue 15-pin connector: The VGA port typically has 15 pins arranged in three rows.
- Analog signal: It transmits video data as an analog signal, which can result in lower image quality compared to digital connections like HDMI or DisplayPort.
- Resolution limits: VGA can support resolutions up to 1920×1080 (Full HD), but the quality can degrade at higher resolutions.
Although it’s being phased out in favor of digital connections, you might still find VGA ports on some older laptops and monitors. For better image quality, most modern laptops use HDMI, DisplayPort, or USB-C instead of VGA.
