A monochrome monitor displays only one foreground color and one background color. Usually the monitor was manufactured to produce only one color, which was cheaper (both CRT and electronics) than a color monitor.
Was there a monitor that accepted a monochrome signal, but then allowed a choice of foreground (or background) colors? For example, had an option to choose between green-on-black and amber-on-black?
Inverse/Reverse video is not the subject of this question.
This question is asking about such a capability in the monitor, not in the computer. Certainly, there were many computers that sent a color signal but had monochrome display modes with configurable colors, but that is not the question here. This is not about having several monochrome modes generated by the computer.
- Why are a lot of monochrome computer monitors green?
- Why were early personal computer monitors not green?
- Why green phosphor instead of amber?
- What were other colors beside green and amber for monochrome monitors?
- Is there a device that will take composite video from a vintage computer and filter it so it is green or amber like the old monochrome monitors? (a device between the computer and monitor)
- Exactly what color was the text on monochrome terminals with green-on-black and amber-on-black screens?
