A computer monitor is an output device that displays information in pictorial form. A monitor comprises the display device, circuitry and power supply; the display device in modern monitors is a thin film transistor liquid crystal display with LED backlighting having replaced cold-cathode fluorescent lamp backlighting. Older monitors used a cathode ray tube. Monitors are connected to the computer via VGA, Digital Visual Interface, HDMI, DisplayPort, low-voltage differential signaling or other proprietary connectors and signals. Computer monitors were used for data processing while television sets were used for entertainment. From the 1980s onwards, computers have been used for both data processing and entertainment, while televisions have implemented some computer functionality; the common aspect ratio of televisions, computer monitors, has changed from 4:3 to 16:10, to 16:9. Modern computer monitors are interchangeable with conventional television sets. However, as computer monitors do not include integrated speakers, it may not be possible to use a computer monitor without external components.
Early 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. 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 limited amount of information and were transient, they were considered for program output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program's operation; as technology developed engineers realized that the output of a CRT display was more flexible than a panel of light bulbs and 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 known as visual display units, but this term had fallen out of use by the 1990s. Multiple technologies have been used for computer monitors.
Until the 21st century most used cathode ray tubes but they have been superseded by LCD monitors. The first computer monitors used cathode ray tubes. Prior to the advent of home computers in the late 1970s, it was common for a video display terminal 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 large text and limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for the specialized military and scientific applications but they were far too costly for general use; some of the earliest home computers were limited to monochrome CRT displays, but color display capability was a standard feature of the pioneering Apple II, introduced in 1977, the specialty of the more graphically sophisticated Atari 800, introduced in 1979. 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 1981 IBM introduced the Color Graphics Adapter, which could display four colors with a resolution of 320 x 200 pixels, or it could produce 640 x 200 pixels with two colors. In 1984 IBM introduced the Enhanced Graphics Adapter, capable of producing 16 colors and had a resolution of 640 x 350. By the end of the 1980s color CRT monitors that could display 1024 x 768 pixels were available and affordable. During the following decade, maximum display resolutions increased and prices continued to fall. CRT technology remained dominant in the PC monitor market into the new millennium because it was cheaper to produce and offered to view angles close to 180 degrees. CRTs still offer some image quality advantages over LCDs but improvements to the latter have made them much less obvious; the dynamic range of early LCD panels was poor, 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.
There are multiple technologies. Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, smaller physical size of LCDs justified the higher price versus a CRT; the same laptop would be offered with an assortment of display options at increasing price points: monochrome, passive color, or active matrix color. As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines. TFT-LCD is a variant of LCD, now the dominant technology used for computer monitors; the first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined over a period of years they became more popular, by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo L66 in the mid-1990s, the Apple Studio Display in 1998, the Apple Cinema Display in 1999. In 2003, 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
The Milwaukee County School of Agriculture and Domestic Economy Historic District is the building complex of an agriculture school started in 1912 in Wauwatosa, when farming was a big part of Milwaukee County's economy. In 1998 the complex was listed on the National Register of Historic Places; the district was a high school campus from 1912 to 1928, aiming to train young farmers, rather than have them quit school after 6th grade. It was the third such agriculture-focused high school in the state, following similar schools in Dunn and Marathon counties, it was the largest. Alexander C. Eschweiler designed its buildings. There are five buildings, all with walls of red brick: The 1911 University building is 1.5 stories, Tudor Revival style, with bargeboards. The 1911 Class Building is 1.5 stories, in Tudor Revival style, decorated with bargeboards. The 1911 Administration building is Collegiate Gothic style; the 1911 Dairy Building is 2.5 stories, with exposed rafter tails. The 1911 Horticulture building was 1.5 stories, in a mix of Collegiate Gothic and Tudor Revival styles.
It was demolished in 1995
Breath of Life is a 1990 Italian drama film directed by Beppe Cino. It is an adaptation of Gesualdo Bufalino's 1981 novel, Diceria dell'untore; the film, starring Franco Nero and Vanessa Redgrave was released in Italy on 11 October 1990. In 1946, Gesualdo is a recovering Second World War soldier in a Palermo TB clinic. Most of the patients are aware of their impending death. Gesualdo holds the same bleak expectations, yet miraculously he recovers. Gesualdo is the only survivor.
