• A computer monitor is a device that displays information in the form of graphics or text. A monitor consists of a visual display, circuitry, a housing, and a power source. In modern monitors, the display technology is usually a thin film transistor liquid crystal display (TFT-LCD), with LED backlighting replacing cold-cathode fluorescent lamp (CCFL) backlighting.
• A cathode ray tube (CRT) and certain Plasma (also known as Gas-Plasma) displays were utilised in previous monitors. VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, USB-C, low-voltage differential signalling (LVDS), and other proprietary connectors and signals are used to connect monitors to computers.
