Description: Extended Graphics Array (XGA) is a display standard developed by IBM in 1990 that provides a resolution of 1024×768 pixels. This screen format is characterized by its ability to display high-quality graphics and a color palette of up to 256 colors simultaneously. XGA was designed to improve visual quality compared to its predecessors, such as VGA (Video Graphics Array), which offered a maximum resolution of 640×480 pixels. The implementation of XGA allowed users to enjoy more detailed graphics and a richer visual experience, which was especially beneficial for graphic design applications, video games, and presentations. Additionally, XGA introduced an extended screen mode that allowed users to work with multiple windows and applications simultaneously, enhancing productivity. Over the years, XGA became a widely adopted standard in the computing industry, being used in monitors, projectors, and graphics cards, and laid the groundwork for more advanced resolutions in the future, such as SXGA and UXGA.
History: XGA was introduced by IBM in 1990 as part of its series of graphics adapters. This standard was a response to the growing demand for better graphics capabilities in personal computers, especially for applications that required higher resolution and image quality. As technology advanced, XGA evolved and became a de facto standard in the industry, being widely used in monitors and projectors during the 1990s and early 2000s. Over time, enhanced versions were developed, such as XGA+, which offered even higher resolutions.
Uses: XGA is primarily used in computer monitors, projectors, and graphics cards. Its ability to display high-resolution graphics made it ideal for graphic design applications, business presentations, and video games. Additionally, XGA was widely adopted in educational and corporate environments where clear and detailed information visualization was required.
Examples: An example of XGA usage can be found in many classroom projectors from the 1990s, which used this resolution to display presentations and educational materials. It was also used in mid-range CRT and LCD monitors during that period, providing adequate image quality for various office and entertainment applications.
