RGB vs. VGA: Know the Difference
By Shumaila Saeed || Published on February 15, 2024
RGB refers to a color model using red, green, and blue light; VGA is a video display interface standard for transmitting video signals.
Key Differences
RGB (Red, Green, Blue) is a color model used in various devices for the representation and display of images. VGA (Video Graphics Array), in contrast, is a video transmission standard that defines a specific method of transmitting video signals from a source to a display.
