Computer monitor

A computer monitor is an electronic display device that presents visual output from a computer. It converts image signals into visible text, graphics, and video.

Display resolution: The number of distinct pixels a display can show, usually stated as width by height. Resolution sets the fine detail visible on a monitor.
Graphics processing unit: A processor designed to accelerate the creation and manipulation of images and other parallel workloads. The GPU commonly generates the frames that a monitor displays.
Color calibration: The adjustment of a display or imaging device so its output matches specified color and tonal targets. Calibration makes monitor colors more reliable for editing and proofing.
Television: An electronic device or system for receiving and displaying broadcast or streamed audiovisual programming. Televisions and monitors overlap technically but differ in typical use and features.
Pixel: The smallest addressable picture element in a digital image or display. A monitor forms images by controlling grids of pixels.
Framebuffer: A memory region containing pixel values for an image being displayed. The framebuffer holds image data before it is sent to the monitor.
Color gamut: The range of colors a device or color space can represent. A monitor's gamut limits which saturated colors it can reproduce.
Projector: An optical device that projects an image onto a separate surface. A projector forms a large image on a screen rather than on its own panel.
Liquid-crystal display: A flat-panel display technology that uses liquid crystals to modulate light from a backlight. LCD panels are a common way monitors create colored pixels.
RGB color model: An additive color model that represents colors through combinations of red, green, and blue light. Monitor pixels commonly combine red, green, and blue subpixels.
