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'. Įarly electronic computers were fitted with a panel of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer.

However, as many computer monitors do not include integrated speakers nor TV Tuners (such as digital television adapters), it may not be possible to use a computer monitor as a TV set without external components. Modern computer monitors are easily interchangeable with conventional television sets and vice versa. The common aspect ratio of televisions, and computer monitors, has changed from 4:3 to 16:10, to 16:9.
From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality. Originally, computer monitors were used for data processing while television sets were used for entertainment. Monitors are connected to the computer via VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, USB-C, low-voltage differential signaling (LVDS) or other proprietary connectors and signals. Previous monitors used a cathode ray tube (CRT) and some Plasma (also called Gas-Plasma) displays. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting.
A monitor usually comprises a visual display, some circuitry, a casing, and a power supply. A cathode-ray tube (CRT) computer monitorĪ computer monitor is an output device that displays information in pictorial or text form.
