TouchScreenMonitorSerialPortComputer monitor Wikipedia. LCD computer monitors in a computer lab. A computer monitor is an output device which displays information in pictorial form. A monitor usually comprises the display device, circuitry, casing, and power supply. 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. Older monitors used a cathode ray tube CRT. Monitors are connected to the computer via VGA, Digital Visual Interface DVI, HDMI, Display. Damon February 4, 2016.

Port, Thunderbolt, low voltage differential signaling LVDS or other proprietary connectors and signals. Originally, computer monitors were used for data processing while television receivers were used for entertainment. From the 1. 98. 0s onwards, computers and their monitors have been used for both data processing and entertainment, while televisions have implemented some computer functionality. The common aspect ratio of televisions, and computer monitors, has changed from 4 3 to 1. HistoryeditEarly electronic computers were fitted with a panel of light bulbs where the state of each particular bulb would indicate the onoff state of a particular register bit inside the computer. 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. 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. HTB1zAAoQVXXXXXSapXXq6xXFXXX0/cheap-price-serial-parallel-port-19-inch.jpg' alt='Touch Screen Monitor Serial Port' title='Touch Screen Monitor Serial Port' />Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the programs operation. As technology developed engineers realized that the output of a CRT display was more flexible than a panel of light bulbs and eventually, by giving control of what was displayed in the program itself, the monitor itself became a powerful output device in its own right. Computer monitors were formerly known as visual display units VDU, but this term had mostly fallen out of use by the 1. TechnologieseditMultiple technologies have been used for computer monitors. Until the 2. 1st century most used cathode ray tubes but they have largely been superseded by LCD monitors. Cathode ray tubeeditThe first computer monitors used cathode ray tubes CRTs. Prior to the advent of home computers in the late 1. VDT using a CRT to be physically integrated with a keyboard and other components of the system in a single large chassis. The display was monochrome and far less sharp and detailed than on a modern flat panel monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High resolution CRT displays were developed for the specialized military, industrial and scientific applications but they were far too costly for general use. Some of the earliest home computers such as the TRS 8. Commodore PET were limited to monochrome CRT displays, but color display capability was already a standard feature of the pioneering Apple II, introduced in 1. Atari 8. 00, introduced in 1. Either computer could be connected to the antenna terminals of an ordinary color TV set or used with a purpose made CRT color monitor for optimum resolution and color quality. Lagging several years behind, in 1. Touchmonitors/1515/Touch-ready.png' alt='Touch Screen Monitor Serial Port' title='Touch Screen Monitor Serial Port' />IBM introduced the Color Graphics Adapter, which could display four colors with a resolution of 3. In 1. 98. 4 IBM introduced the Enhanced Graphics Adapter which was capable of producing 1. Word 6 For Mac Os X. By the end of the 1. CRT monitors that could clearly display 1. During the following decade, maximum display resolutions gradually increased and prices continued to fall. CRT technology remained dominant in the PC monitor market into the new millennium partly because it was cheaper to produce and offered to view angles close to 1. CRTs still offer some image quality advantagesclarification needed over LCDs but improvements to the latter have made them much less obvious. The dynamic range of early LCD panels was very poor, and although text and other motionless graphics were sharper than on a CRT, an LCD characteristic known as pixel lag caused moving graphics to appear noticeably smeared and blurry. Liquid crystal displayeditThere are multiple technologies that have been used to implement liquid crystal displays LCD. Throughout the 1. LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points active or passive monochrome, passive color, or active matrix color TFT. As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines. Bluechart G2'>Bluechart G2. TFT LCD is a variant of LCD which is now the dominant technology used for computer monitors. The first standalone LCDs appeared in the mid 1. As prices declined over a period of years they became more popular, and by 1. CRT monitors. Among the first desktop LCD computer monitors was the Eizo L6. Apple Studio Display in 1. Apple Cinema Display in 1. In 2. 00. 3, TFT LCDs outsold CRTs for the first time, becoming the primary technology used for computer monitors. The main advantages of LCDs over CRT displays are that LCDs consume less power, take up much less space, and are considerably lighter. The now common active matrix TFT LCD technology also has less flickering than CRTs, which reduces eye strain. On the other hand, CRT monitors have superior contrast, have a superior response time, are able to use multiple screen resolutions natively, and there is no discernible flicker if the refresh rate is set to a sufficiently high value. LCD monitors have now very high temporal accuracy and can be used for vision research. High dynamic range HDR has been implemented into high end LCD monitors to improve color accuracy. Since around the late 2. LCD monitors have become popular, in part due to television series, motion pictures and video games transitioning to high definition HD, which makes standard width monitors unable to display them correctly as they either stretch or crop HD content. These types of monitors may also display it in the proper width, however they usually fill the extra space at the top and bottom of the image with black bars. Other advantages of widescreen monitors over standard width monitors is that they make work more productive by displaying more of a users documents and images, and allow displaying toolbars with documents. They also have a larger viewing area, with a typical widescreen monitor having a 1. Organic light emitting diodeeditOrganic light emitting diode OLED monitors provide higher contrast and better viewing angles than LCDs but they require more power when displaying documents with white or bright backgrounds. In 2. 01. 1, a 2. OLED monitor cost 7. Measurements of performanceeditThe performance of a monitor is measured by the following parameters Luminance is measured in candelas per square meter cdm. Nit. Aspect ratio is the ratio of the horizontal length to the vertical length. Monitors usually have the aspect ratio 4 3, 5 4, 1.
