computermonitor

A computer monitor, sometimes written as computermonitor, is an output device that displays graphical information generated by a computer. It consists of a display panel, backlight, and circuitry housed in a frame, and provides a visual interface for text, images, and video.

Most modern monitors are flat-panel LCDs with LED backlighting or OLED panels. LCD/LED models are common for general use; OLED offers high contrast and fast response but can risk burn-in. Display sizes typically range from about 21 to 34 inches, with higher-end models larger.

Common resolutions include Full HD (1920x1080), Quad HD (2560x1440), and 4K (3840x2160). Refresh rates vary from 60 Hz in standard displays to 120 Hz, 144 Hz, or higher in gaming-oriented models, often with adaptive sync technologies to reduce tearing.

Connectivity options include HDMI, DisplayPort, DVI, and VGA, with USB-C increasingly common for video, data, and power. Color accuracy, contrast ratio, and brightness affect image quality, with professional monitors offering factory calibration and wider color gamuts.

Ergonomics are important for comfort, including adjustable tilt, height, and swivel, and support for VESA mounting. Blue light filters and anti-glare coatings are common features to reduce eye strain.

Historically, CRT displays were replaced by LCDs in the early 2000s; OLED and ultrawide LCDs are newer trends. Monitors are used in computing, gaming, media creation, and professional work, with choices balancing size, resolution, panel type, response time, and connectivity.
