Which of the following devices qualify as display devices for outputting information?

Display devices are specifically designed to visually present information, typically through images, text, or video. Monitors fall into this category as they are the primary interface used to display graphical and textual information from a computer. They directly connect to the computer system and produce output that users can see.

Television sets also function as display devices, as they can receive video signals and present them visually. However, their primary purpose is for broadcasting video content rather than serving as a direct output interface for computing tasks.

Printers produce hard copies of digital documents and hence are classified as output devices but not display devices since they do not show information on a screen. Microphones operate as input devices by capturing sound and converting it into electrical signals, which means they do not output visual information at all.

In the context of this question, while monitors are definitive display devices, television sets could be considered for video output purposes but do not primarily serve as output devices from a computer in the same capacity as monitors do. Therefore, monitors are the most appropriate choice for a display device in a computing context.
