What is a video display that only shows black and white called?

• A. Binary
• B. Monochrome
• C. Bistable
• D. Unichrome

Answer: (C)

The term that describes a video display showing only black and white is "monochrome." This is because "mono-" means one or single, and "chrome" refers to color, so a monochrome display presents images in varying shades of a single color, which in this case is black (and white). Monochrome displays were common in early computer monitors and televisions before color technology became widely available.

The other options do not accurately define a display that only shows black and white. "Binary" typically refers to a system with only two possible states, but it is not specifically related to video displays. "Bistable" refers to a system that has two stable states, which is not a standard term for video displays. "Unichrome" is generally not a recognized term in this context and does not describe black and white displays specifically.
