Monitor

An output device that displays information in text or graphic form is called a computer monitor. A visual display, some circuitry, a casing, and a power source usually make up a monitor.

What is Monitor?

A monitor commonly referred to as a video display terminal (VDT) or a video display unit, is an electronic output device (VDU). A computer’s video card is used to display images, text, video, and graphical data produced by a connected computer. Although it almost looks like a TV, it has a far greater resolution. On March 1st, 1973, the Xerox Alto computer system debuted with the first computer monitor.

Older monitors occupied more desk space as they were heavier and larger in size due to the use of fluorescent screens and cathode ray tubes (CRTs). All modern monitors are built with flat-panel display technology and often have LED backlighting. Compared to earlier CRT screens, these contemporary monitors are smaller and take up less desk space.

Types of Monitors

New monitors are being developed in response to changing times. There are many different types of monitors on the market today, some of which are listed here:

• CRT (Cathode Ray Tube) Monitor
• Flat Panel Monitor
• Touch Screen Monitor
• LED Monitor
• OLED Monitor
• DLP Monitor
• TFT Monitor
• Plasma Screen Monitor

History of Monitor

• The Uniscope 300 device had a built-in CRT display in 1964 but was not a true computer monitor.
  Touch screen technology was introduced in 1965 by A. Made by Johnson.
• The first computer display was a feature of the Xerox Alto computer, released on March 1, 1973. This monitor used CRT technology and had a monochrome display.
• The first resistive touch screen display was created by George Samuel Hurst in 1975, although it was already in use before 1982.
• The Apple I and Sol-20 computer systems were unveiled in 1976. A built-in video connector on these computers made it possible to play a video screen on a computer monitor.
• James P. Mitchell created the LED display technology in 1977. However, even 30 years later, it was difficult to bring these monitors to market.

• The Apple II was released in June 1977, enabling colour display on a CRT monitor.
• The first VGA monitor, the IBM 8513, was made available in 1987.
• The SVGA computer display standard was established by VESA in 1989.
• The 1024 × 768 resolution display on colour CRT displays was supported in the late 1980s.
• The first LCD monitors for desktop computers, the Eizo L66, were created by Eizo Nanao and released in the middle of the 1990s.
• The development of colour LCD monitors, which offer superior quality and resolution to CRT panels, began in 1997 with IBM, Viewsonic, and Apple.

• Apple started producing desktop computer colour LCD monitors in 1998.
• Later in 2003, LCD displays overtook CRT monitors in sales for the first time. CRT monitors were continually outsold by LCD displays until 2007 when they overtook CRT monitors in popularity.
• At TED in 2006, Jeff Han unveiled the first touchscreen monitor without an interface.
• The NEC firm introduced the LED display MultiSync EA222WMe in 2009. It was NEC’s first monitor to be made available.
• In December 2010, AMD and Intel stated they will stop supporting VGA.
• Touch screen LCD monitors started to drop in price in 2017, making them more accessible to consumers.

Types of Monitor Connectors

Just as there are different types of monitors available in the market, in the same way, different types of connectors have been made to connect the monitor to the computer. Connecting a computer monitor to a computer requires one of the following types of connectors.

• VGA
• thunderbolt
• HDMI
• USB-C
• DVI
• DisplayPort
