Either normal/bright or normal/dim (1 bit) per character as in the VT100 or black, dark gray, light gray, white (2bit) per pixel like the NeXT MegaPixel Display. Typically, only a limited set of brightness levels was provided to save display memory which was very expensive in the '70s and '80s. Some monitors have the ability to vary the brightness of individual pixels, thereby creating the illusion of depth and color, exactly like a black-and-white television. All text and graphics are displayed in that color. Unlike color monitors, which display text and graphics in multiple colors through the use of alternating-intensity red, green, and blue phosphors, monochrome monitors have only one color of phosphor ( mono means "one", and chrome means "color"). The most common technology for monochrome monitors was the CRT, although, e.g., plasma displays, were also used. It uses a GoldStar Type 310KGLA amber tube.
