One of the first uses of a standalone computer monitor with a personal computer was with the Apple 1, which connected directly to a consumer television as a monitor instead of using a glass terminal as its output.Ĭomputer monitors were formerly known as visual display units ( VDU), particularly in British English. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program's operation. As early monitors were only capable of displaying a very limited amount of information and were very transient, they were rarely considered for program output. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the 'monitor'. History Įarly electronic computer front panels were fitted with an array of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. As most computer monitors do not include integrated speakers, TV tuners, or remote controls, external components such as a DTA box may be needed to use a computer monitor as a TV set. Modern computer monitors are often functionally interchangeable with television sets and vice versa. In the 2000s, the typical display aspect ratio of both televisions and computer monitors changed from 4:3 to 16:9. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. Originally, computer monitors were used for data processing while television sets were used for video. ![]() Less commonly, monitors sometimes use other proprietary connectors and signals to connect to a computer. A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, DVI, or VGA. Before the mid- 2000s, most monitors used a cathode-ray tube (CRT) as the image output technology. The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls.
