XGA, an abbreviation for Extended Graphics Array, is a computer display standard that refers to a resolution of 1024x768 pixels. It is an improvement on the earlier VGA (Video Graphics Array) standard and was introduced in the early 1990s. XGA provides a higher resolution and improved image quality compared to VGA, making it suitable for a variety of applications such as business presentations, gaming, and multimedia.
With a pixel count of 786,432, XGA supports a 4:3 aspect ratio, which is the traditional display ratio used in CRT (Cathode Ray Tube) monitors. It offers a sharp and clear display with enhanced color depth, allowing for better representation of graphics, text, and multimedia content. The increased resolution of XGA makes it ideal for showing detailed images and text, as well as multitasking with multiple windows or applications.
XGA has become a widely adopted standard in the computer industry, although newer display resolutions such as UXGA (Ultra Extended Graphics Array) and WUXGA (Wide Ultra Extended Graphics Array) have since superseded it in certain high-resolution applications. Nevertheless, XGA remains prevalent in many office environments and in the production of projectors and LCD screens.
Overall, XGA represents a significant improvement in display quality compared to its predecessors, offering a higher resolution and improved visual experience in a 4:3 aspect ratio, making it a popular choice for various computer display applications.
