1024×768

1024×768 is a display resolution consisting of 1024 pixels in width and 768 pixels in height, yielding a 4:3 aspect ratio. It is commonly associated with the XGA (Extended Graphics Array) standard, originally introduced by IBM in 1990 as a higher-resolution successor to VGA and SVGA. The resolution comprises 786,432 individual pixels and is characterized by square pixels on standard displays.

Historically, 1024×768 became a common default for desktop monitors, laptop screens, and many projectors during the late 1990s and early 2000s. It was widely supported by Windows, macOS, and Linux operating systems, and remained a prevalent option for business and educational environments because of its balance between clarity and file size for documents and presentations.

Compatibility and usage: The 4:3 aspect ratio makes 1024×768 well suited for mixed content such as text documents and presentations, but it is increasingly out of step with modern widescreen displays. When used on wide 16:9 screens, content is often letterboxed or scaled, potentially affecting legibility. Many projectors and older displays natively support this resolution, facilitating quick setup for meetings.

Contemporary relevance: While largely supplanted by higher-resolution or widescreen formats such as 1280×800, 1366×768, and 1920×1080, 1024×768 remains in use in legacy equipment, embedded devices, retro computing, and some educational projectors where a 4:3 image is desired or required.
