Can a color display be changed to grayscale?

[ilano]

Hi,

I have a color monitor but I wanted to test a monochrome display on
the same.

Is it possible to convert a color monitor to grayscale?

Thanks,

? That's an odd thing to want...

I'm also not sure what you're trying to do.
Do you want to use a monochromatic display mode (binary pixels but
that's B&W output and completely independant of monitor) or do you want
a colour signal to be outputted in grayscale?

I don't think there's a default way to convert colour output to
grayscale. Perhaps some screen calibration software provides the ability
to tone down colour. Another way is to convert a screenshot to grayscale
or connecting a tv-set to a tvout and tone down the colour gauge.

To answer your exact question:
It entirely depends on your monitor whether or not it can display colour
signals in grayscale. A monochromatic signal (like hercules mode) is
already black and white, so it works by default.

One of the pins on the VGA connector tells the video card whether or not a
colour monitor is attached. In theory, if a monitor is not plugged in at the
time the system boots, the card should consider the monitor to be a black and
white monitor.

The software can read this setting, and display appropriately. Unfortunately,
in practice this does not work, because the functionality to support a
monochrome display has not been coded, resulting in a colour image, even
though the signal for a colour monitor was not given.

Mark.

You could setup Visual to GrayScale in "Display" subsection inside
Screen section.
This should work for 8-bit "Depth" so that you may set "DefaultDepth"
to 8 for used screen.
