Video Resolutions

What the hell do all those cryptic letters about video displays mean? What is VGA? What is SVGA? XGA? Not to mention SXGA, SXGA+, and UGA.

Screen real estate is usually measured in pixels. The more pixels your screen displays, the more stuff you can cram onscreen. Of course, as you pack more pixels into the same area, all those pixels get smaller...

To prevent normal people from understanding what all of us geeks are babbling about, the Geek High Council (in conjunction with the Freemasons and the Trilateral Commission) created a set of specifications for different monitor resolutions. Here are the usual screen sizes, in pixels, for each of these specifications:

The settings above all have an aspect ratio of 4:3; for many years, that was the "standard" width-to-height ratio. Now, however, wider screens are more common, and there are several settings with either a 5:4 or 16:9 ratio (or something fairly close):

For the totally hardcore video experts among you, here's a page with a detailed discussion of aspect ratios: http://www.iki.fi/znark/video/conversion/.
