Arvutimonitoridel, or computer monitors, are electronic visual display devices that showcase information from a computer. They convert electrical signals from a computer's graphics card into visible images on a screen. The primary function of a monitor is to allow users to interact with their computer by providing visual feedback for their actions.

Early computer monitors were often cathode ray tube (CRT) based, utilizing a vacuum tube with an electron gun to illuminate pixels on a phosphor-coated screen. These were bulky and consumed significant power. Modern monitors are predominantly liquid crystal display (LCD) or light-emitting diode (LED) based. LCD monitors use a backlight (often LEDs) to illuminate liquid crystals that selectively block or allow light to pass through colored filters, forming images. LED monitors are a type of LCD monitor where the backlight is composed of LEDs, offering improved contrast, brightness, and energy efficiency.

Key specifications for computer monitors include screen size, measured diagonally in inches; resolution, which is the number of pixels displayed horizontally and vertically (e.g., 1920x1080 for Full HD); refresh rate, indicating how many times per second the image on the screen is updated (measured in Hz); and response time, the time it takes for a pixel to change from one color to another (measured in milliseconds). Color accuracy and viewing angles are also important considerations for professional use. The connection interface, such as HDMI, DisplayPort, or older VGA, determines how the monitor connects to the computer.
