Answer:
A computer monitor is an electronic device that displays digital images generated by a computer's graphics card. It is one of the essential components of a computer system, allowing users to interact with the computer and view its output. Monitors come in various sizes, resolutions, and display technologies such as LCD, LED, OLED, and CRT.
Modern computer monitors usually have a flat-panel display, which is thinner and consumes less power than the older CRT (cathode ray tube) monitors. Monitors can be connected to the computer through various interfaces, such as VGA, DVI, HDMI, and DisplayPort, and some models have built-in speakers or USB ports for added functionality.
The resolution of a monitor determines the number of pixels it can display horizontally and vertically, with higher resolutions providing more screen real estate and sharper images. Refresh rate is another important factor, with higher refresh rates allowing for smoother motion and reducing eye strain.
In summary, a computer monitor is an essential component of a computer system that displays visual output to the user, and choosing the right monitor for your needs depends on factors such as size, resolution, display technology, and connectivity options.
