VGA or HD15 is the analog connection used to connect computers and laptops to projectors or additional monitors. In light of Analog Sunset, VGA is considered a legacy connector, and will be replaced with a digital HDMI or DisplayPort connector in the near future.
The VGA standard transmits the image from the video card to the monitor using an analog format. The fact that it's analog means that the image can degrade while getting from the video card to the monitor. The higher the image resolution and refresh rate, the more that the image degrades.
