Monitor resolution?

Currently 1024×768 (XGA/XVGA, eXtended), 1280×1024 (SXGA Super eXtended Graphics Array), and 1600×1200 resolution (UXGA, Ultra-eXtended) are the most common display resolutions. Many computer users including CAD users, graphic artists and video game players run their computers at 1600×1200 resolution (UXGA, Ultra-eXtended) or higher if they have the necessary equipment - although 1280×1024 (SXGA Super eXtended Graphics Array) is more widespread as it is the optimum resolution of most 19" monitors. When a computer display resolution is set higher than the physical screen resolution, some systems make the virtual screen scrollable over the physical screen, however, most CRT monitors will accept higher resolutions than their native resolution without scrolling. The true maximum resolution is calculated from the dot pitch. Few CRT manufacturers will quote the true native resolution in their documentation, but most LCD manufacturers do. With digital television and HDTV, vertical resolutions of 720 or 1080 scan lines are typical.
