A
high-resolution video standard for
PCs developed by
IBM in 1987. It is designed to extend the capabilities of
VGA. The 8514/A
standard provides a resolution of 1,024 by 768
pixels, which gives it about 2.5 times the pixels of VGA (640 by 480). Like VGA, 8514/A provides a
palette of 262,000 colors, of which 256 can be displayed at one time. On
monochrome displays, 8514/A provides 64 shades of gray.
In its original version, 8514/A relies on interlacing, a technique that makes it possible to provide resolution at low cost. Interlacing, however, carries a performance penalty, so many manufacturers produce noninterlaced 8514/A clones.
In 1990, IBM released the Extended Graphics Array (XGA ) standard, which supersedes 8514/A.
