A monitor is a device used to display visual output from a computer or other electronic device. It is also sometimes referred to as a computer screen or display.
Monitors come in a variety of sizes, resolutions, and types. Some common types of monitors include:
LCD (liquid crystal display) monitors: These are the most common type of monitor and use a thin layer of liquid crystal material to display images.
LED (light-emitting diode) monitors: These monitors use LED backlighting to provide more vibrant colors and improved contrast compared to LCD monitors.
CRT (cathode ray tube) monitors: These are older-style monitors that use a vacuum tube to display images.
OLED (organic light-emitting diode) monitors: These monitors use organic materials to emit light, resulting in better contrast and color accuracy compared to LCD and LED monitors.
In addition to size and type, monitors can also differ in resolution, which refers to the number of pixels that make up the display. Higher resolutions generally provide sharper images, but also require more powerful hardware to drive them. Monitors can be connected to a computer using a variety of cables, including VGA, DVI, HDMI, and DisplayPort. Some monitors also have built-in speakers, allowing them to be used for audio output as well.
