HD Zero Frame Monitors
Very important is an output device. Without that the computer can not imagine. Monitor is the picture, text, video that appears on the screen like a television.
A computer monitor is an output device that displays information in a graphical form. A monitor usually has a display device, circuitry, casing and a power supply. The modern monitor’s display device usually consists of a thin film transistor liquid crystal display (TFT-LCD) with LED back lighting replacing cold-cathode fluorescent lamp (CCFL) back lighting. Old monitors used cathode ray tubes (CRTs). Monitors are connected to the computer via VGA, digital visual interface (DVI), HDMI, disproportional, thunderbolt, low-voltage differential signaling (LVDS) or other proprietary connectors and signals.
Basically, computer monitors were used for data processing while television sets were used for entertainment. From the 7’s onward, computers (and their monitors) have been used for both data processing and entertainment, while televisions have worked to improve computer performance. The aspect ratio for television and computer monitors has changed from 4: 3 to 16:10 to 16: 9.
Modern computer monitors are easily interchangeable with conventional television sets. However, since computer monitors do not necessarily include integrated speakers, it may not be possible to use computer monitors without external components.
Early electronic computers had a panel of light bulbs mounted where the status of each particular bulb would indicate the on or off position of a particular article inside the computer. This allowed computer-operated engineers to monitor the internal state of the machine, so this panel of lights became known as the ‘monitor’. Because early monitors were only able to display a very limited amount of information and were very transient, they were rarely considered for program output. Instead, a line printer was the primary output device, while the monitor was limited in monitoring the performance of the program.
When engineers of technology development realized that the output of the CRT display was more flexible than the panel of light bulbs and, ultimately, with control of what was displayed in the program, the monitor itself turned into a powerful output device.
Computer monitors were formerly known as visual display units (VDUs), but this term was largely out of use in the 1990s.
