5/3 Ok I need a refresher class on acronyms. Please modify/correct, thanks.
\_ CGA, 1980s: 320x200x4 (256000 bits)
\_ EGA, 1985s: 320x200x16 (1024000 bits)
\_ MGA,
\_ MGA, 742x350, mono color.
\_ VGA, 1990s: 640x480x16 (4915200 bits)
\_ SVGA, 1995: 1024x768x16 (12582912)
\_ XGA, ????: 1024x768
\_ SXGA, ????: 1280x1024
\_ SXGA+, ????: 1400x1050
\_ WSXGA+ 2005: 1680x1050x(2^32)
\_ Just google for wikipedia xga and click on the http://answers.com link
\_ UXGA: 1600x1200
\_ WUXGA: 1920x1200
\_ http://www.i386.info/vidres.htm
http://en.wikipedia.org/wiki/Computer_display_standard
\_ WQUXGA: 3840X2400
\_ IBM T221 LCD panel, 4 single link DVI required. -ax
\_ Can any modern (2004/2005) VGA card handle resolutions this high
(with BIOS updated, etc), or you have to buy vendor specific
cards to be compatible with these displays?
\_ I think they should just stop using these acronyms. It's way too
confusing. Why not just use the numbers directly?
\_ OMGWTFGA ??? |
| www.i386.info/vidres.htm Video Resolutions What the hell do all those cryptic letters about video displays mean? The more pixels your sc reen displays, the more stuff you can cram onscreen. Of course, as you p ack more pixels into the same area, all those pixels get smaller... To prevent normal people from understanding what all of us geeks are babb ling about, the Geek High Council (in conjunction with the Freemasons an d the Trilateral Commission) created a set of specifications for differe nt monitor resolutions. Here are the usual screen sizes, in pixels, for each of these specifications: * VGA - 640 X 480 * SVGA - 800 X 600 * XGA - 1024 X 768 * QVGA - 1280 X 960 * SXGA+ - 1400 X 1050 * UXGA - 1600 X 1200 * QXGA - 2048 X 1536 * QSXGA+ - 2800 X 2100 * QUXGA - 3200 X 2400 The settings above all have an aspect ratio of 4:3. |
| en.wikipedia.org/wiki/Computer_display_standard SXGA Super XGA, a de facto standard with a resolution of 1280 1024 with 32 bit pixels, true colour. This is an unusual resolution because the numbers work out for a 5:4 display rather than a 4:3 one, so many images appear wider on SXGA displays than most other resolutions. XGA-2 added 1024 768 support for high colour and higher refresh rates, improved performance, and supports 1360 1024 in 16 colours (4 bits per pixel). VGA Video Graphics Array is actually a set of different resolutions, but is most commonly used today to refer to 640 480 pixel displays with 16 colours (4 bits per pixel) and a 4:3 aspect ratio. However, whereas VGA had 256k of video memory, MCGA only had 64k, and was limited to black and white at 640x480 and limited to 320x200 for 256 color operation. CGA can display 80 25 or 40 25 text in 16 colours (4 bits per pixel), 640 200 pixels graphics in 2 colours (1 bit per pixel) or 320 200 in 4 colors (2 bits per pixel) (IBM PC video modes 0-6). |
