[comp.windows.ms] The elusive grayscale display

peter@cbnewsc.ATT.COM (peter.pavlovcik) (02/02/90)

I am trying to figure out how to use my EGA color display
to work as a grayscale B/W terminal with windows.

I asked OnLine, but their answer was:

	1) use control.exe to change all the colors
	   to B/W (which is a really silly answer), or
	
	2) re-install the windows specifying an EGA
	   high resolution B/W monitor.


Both of the above result in a B/W picture, where the gray shades are
crudely emulated, not a true grayscale display. What makes me mad is
that I've seen this done before on the very machine I am using, but
the guy who did it no longer works here. Any wizards out there?

One solution to make you're EGA into a gray scale display
would be to get hDC's 16 color drivers for windows.  This would
give you 4 gray shades to play with in your colors setup.  With
their color utility, you can force the entire pallette (spelling?)
to be only gray scale.  A warning, though: this only changes what
you see on the screen (I think) and doesn't affect window's internal
color number, so if program X thinks it's putting out the hex value for
blue, and hDC Color makes it look like gray, if you dumped it to a printer
it would still come out blue (If possible).  So if you want gray scale
so it matches printer output, you're best off installing as a black&white
EGA.
