UXGA stands for Ultra Extended Graphics Array, a display resolution of 1600 x 1200 pixels. It is commonly used in computer monitors and projectors, providing a high-quality image with a 4:3 aspect ratio. UXGA offers improved clarity and detail compared to lower resolutions, making it suitable for various applications, including graphic design and video editing. This resolution is part of the VESA (Video Electronics Standards Association) standards, which define display resolutions and formats. While UXGA was popular in the early 2000s, it has largely been replaced by higher resolutions like WUXGA (1920 x 1200) and QHD (2560 x 1440) in modern devices.
