Can MSWindows support more than 16-colors? If so, do any of the
graphics board manufacturers support more?
The reason I ask this question is that I own a Vega-VGA board from
Video-7. In addition to normal EGA and VGA support for windows,
Video 7 also provides Windows drivers for higher resolutions:
800 x 600 and 720 x 540. However, these drivers support just 16
colors. I was hoping for a Windows driver that would support
320 x 200 x 256 COLORS! (From what I have seen of the quality
of GIF pictures in this VGA mode, I would think that this tradeoff
of resolution for color-quality would be welcomed by many.)
Can anyone know of ANY manufacturer supporting this VGA mode under
MSWindows?

However, color bitmaps are NOT device independent. That is, a color bitmap designed for the Windows EGA or VGA drivers (which are 3 planes, 1 bit per pixel -- that is -- 8 colors) are not displayable on an IBM 8514/A display adaptor (that is 8 bits per pixel, 1 plane -- that is -- 256 colors.) > > The reason I ask this question is that I own a Vega-VGA board from > Video-7.

There are no VGA drivers for this resolution. The reason being is that text (which is probably the most important part of Windows), would be undisplayable at such a low resolution. However, take heart, if you wish to spend some money, you can purchase an IBM 8514/A display adaptor for which there is a Windows driver at 1024 by 768 by 256 colors. In addition, there will be, in a couple of months, a device independent display driver for boards supporting the TI 34010 TiGA graphics standard. Therefore, you can purchase any board based on the 34010 which supports TiGA and obtain a Windows driver that will fill your needs. I believe that there is also
