The D-sub monitor input has 15 pins arranged in three rows that carry video signals from a computer’s graphic display device to a monitor. The term D-sub refers to the D-shape of the connectors and the size (sub-miniature). Most D-sub connectors support VGA, which is the analog video signal standard.Know More
D-sub monitor inputs include a female port on the computer for graphic display output, a cable, and a corresponding male port on the monitor. Commercial cables have a molded connector on each end, one male and one female, each with a D-shaped metal shield and three rows with five pins each. The port on the computer uses a female socket, while the port on the monitor uses a male socket. Two thumbscrews on either side of the cable plugs provide strain relief and secure the cable in the respective ports. The D-shapes ensure correct plug orientation. Other types of ports and cables also use the D-shaped connection design but have many more pin and socket connections and layouts.
Introduced by IBM in the late 1980s, the D-sub was small compared to other computer ports, so the term sub-miniature made sense at the time. As digital video signals replaced analog signals, other cable designs such as HDMI have since eclipsed the D-sub.Learn More
When a monitor display shows only a green image, it is usually because the monitor cable is loose. Display signals are outputted in three primary colors: red, green and blue. A monitor may display only green because the red and blue inputs are not connected. Reconnect the monitor cable, and the full color spectrum should return. If it doesn't, the cable may be damaged.Full Answer >
The monitor is the visual interface that allows computer users to see open programs and use applications, such as Web browsers and software programs. It is a standard piece of computing equipment and while monitors were initially used to show basic data processing information in the early days of computing, many people now use their computers for visual entertainment, such as watching TV shows and movies, making the monitor an essential part of the computer user experience. Modern monitors tend to be thin and offer high definition displays in a full range of color, which is a contrast from more primitive computer monitors, which displayed low-res images in limited colors.Full Answer >
