VGA, SVGA, XGA, SXGA, UGA, huh?

Sunday 29 December 2002

I find it amazing that after all these years, PC video resolutions are still expressed with meaningless acronyms rather than simply specifying the resolution in pixels. If the screen can display 1600×1200 pixels, just say so.

Perhaps more remarkable is the difficulty of finding a definition for these acronyms. The most straighforward I found was a small note on this page about video accessories. George Hernandez has a great deal of information, but confusingly lists a number of resolutions for each acronym (and doesn't always agree with other sources!). Wilde's WWW Online Glossary finally proved to be the simplest reference.

Here's what I ended up with:

VGA640×480
SVGA800×600
XGA1024×768
SXGA1280×1024
SXGA+1400×1050
U[X]GA1600×1200
QXGA2048×1536
