What are the major output device?
Typical examples of output devices are monitors and projectors (video), headphones and speakers (audio), or printers and plotters (physical reproduction in the form of text or graphics).
Who invented the output device?
Computer Monitors are output devices. They are output devices because the information is shown out to you on the screen. The process of the computer monitor is just whatever you do with the mouse and keyboard is shown on the screen. The computer monitor was invented in 1897 by Karl Ferdinand Braun.
