640x200

640x200 refers to a display resolution, meaning the screen displays 640 pixels horizontally and 200 pixels vertically. This resolution was common in the early days of personal computing, particularly during the era of the IBM PC and its compatibles. It offered a relatively low pixel count by modern standards but was a significant improvement over earlier monochrome displays.

The 640x200 resolution was often associated with the CGA (Color Graphics Adapter) graphics card, which was one of the first color display options for the IBM PC. This resolution allowed for basic graphics and text to be displayed simultaneously. While capable of displaying a limited palette of colors, the low vertical resolution often resulted in stretched or pixelated images compared to higher resolutions.

Despite its limitations, 640x200 was sufficient for many early applications, including text-based games, productivity software, and early graphical user interfaces. As graphics technology advanced, higher resolutions like 640x480 and beyond became standard, making 640x200 largely obsolete for most modern computing tasks. However, it remains a point of historical reference in the evolution of computer display technology.
