XGA, or Extended Graphics Array, is a display standard developed by IBM in the early 1990s. It offers a resolution of 1024x768 pixels, which provides a clearer and more detailed image compared to its predecessor, VGA (Video Graphics Array). XGA supports both 4:3 and widescreen aspect ratios, making it versatile for various applications. This standard is commonly used in computer monitors, projectors, and other display devices. XGA also supports a range of color depths, allowing for vibrant and accurate color reproduction. Its widespread adoption has made it a foundational technology in the evolution of computer graphics.
