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.
