I see. Monochrome EGA and VGA, both showing simply grayscale screen like below, is it?ppgrainbow wrote:Monochrome VGA is simply a grayscale version of a real VGA screen. Here's a example: http://www.computernerdkev.heliohost.or ... 0035,s.jpg
Monochrome EGA displays can have up to 16 grayscale shades (16 colours out of 64 palette colours). Monochrome VGA displays can have up to 64 grayscale shades (as opposed to 256 colours out of 262,144 palette colours). For monochrome super VGA displays, you can truly have up to 256 grays (as opposed to having 16-bit or 24-bit colours). Here's a example of what a monochrome super VGA monitor looks like: https://www.recycledgoods.com/miracle-m ... or-15-pin/

[EDIT] this picture has expired, sorry...
I think these to monochrome easier way, insert to screen rendering process, not display mode configuration...
rendering EGA/VGA screen to grayscale and change palette like various monochrome screens.
and this way can render color CGA to grayscale, too.
or using shader (CG for D3D, GLSL for OpenGL) from PCem.
