My guess is that you are trying to use monochrome monitors, and not greyscale monitors. When you use a monochrome monitor (such as any tty level monitor I think) you can not take advantage of the analog signals that the VGA board uses for producing the large number of colors that it does. My Orchid ProDesigner and Magnavox Greyscale VGA monitor give me what appears to be 256 shades of grey, although VGA cards are only capable of producing 64 true greyscales. Check your monitor. If it doesn't say that it is a greyscale monitor, or if it is a tty level monitor and not analog, then you probably will not be able to get greyscales out of it. -- Brett McCoy | God is real, unless declared integer brtmac@ksuvm.ksu.edu | bmc@phobos.cis.ksu.edu | If you don't get caught, brtmac@hobbes.ksu.ksu.edu | did you really do it?
