[comp.sys.ibm.pc.hardware] VGA standards for high resolution graphics cards and monitors

annala@neuro.usc.edu (A J Annala) (12/31/90)

I would appreciate recommendation for purchase of a high quality high
resolution VGA card which supports (640 x 480, 800 x 600, 1024 x 768)
256 color display resolution.  I would prefer using a card supporting
whatever standards seem to be evolving for high resolution VGA -- and
if possible capable of supporting operating in linear address (rather
than paged) address space under SCO UNIX SYSV/386 3.2v2.  Because my
project involves image processing it is crucial that the recommended
card support eight bits each of R, G and B so I can display the full
range 256 level enhanced greyscale and 256 color mapped images.

In addition, I would be interested in knowing which VGA cards will be
supported by SCO UNIX SYSV/386 ODT, QEMM/386 X Window Server, Roell's
X Window Server in high resolution 256 color modes.

Thanks, AJ Annala

Standard VGA DAC's are limited to six bits per color(RGB), giving only 
64 shades of grey.  Other than that, the Orchid Prodesigner II supports
the resolutions you desire, and it's a real good card.  I'm not sure about
SCO compatibility though, but it's build on the Tensng Chip Set so it
should be fairly compatible...
