Projector vs. Monitor: What's the Difference?
Edited by Harlon Moss || By Janet White || Updated on October 11, 2023
A projector casts images onto surfaces, while a monitor displays them on its own screen.
Key Differences
A projector and a monitor serve the fundamental role of displaying visual content, but the methods they employ are distinctly different. While a projector throws light to project images or videos onto walls or screens, a monitor showcases them on its integrated screen.
In terms of setup and environment, projectors require a considerable amount of space to display a large image, and they work best in dimly lit conditions. Monitors, conversely, are more versatile with lighting and are confined to their fixed screen sizes.
From a resolution perspective, modern monitors often offer sharper and clearer image quality. However, projectors have the advantage when it comes to screen size variability, capable of producing much larger images than a typical monitor.
The versatility of a projector makes it popular for presentations, home theaters, and educational settings. Monitors, on the other hand, are a staple for computers, gaming, and standard video playback.
It's also worth noting the maintenance aspect. Projectors often need occasional bulb replacements, while monitors, being solid-state, require less frequent maintenance barring screen or component issues.

Projector
An optical instrument which projects an image from a transparency or an opaque image onto a projection screen or other surface, using an intense light and one or more lenses to focus the image. The term projector by itself is usually used for projection of transparent images by passing the light beam through the image; a projector which projects an image of an opaque object is now ususally referred to as an overhead projector. In projection of this latter form the projection is accomplished by means of a combination of lenses with a prism and a mirror or reflector. Specific instruments have been called by different names, such as balopticon, radiopticon, radiopticon, mirrorscope, etc.
