Computer Monitor

You can buy LCD monitors from The Retail Factory. A monitor, or computer display monitor, is the electrical appliance that displays data generated by the computer in the form of pixels that create text, images and colours. The device is usually a cathode ray tube or a flat panel. The most common form of monitor today is an LCD (Liquid Crystal Display) screen.

The monitor is made up of the display device itself, electrical circuitry which takes signals from the computer hardware to generate the display and a case which encloses the display and circuitry.

LCD screens are the most popular choice for new computers but there are also plasma screens, video projectors, organic light-emitting diodes and other monitor display devices. LCD screens have a limited viewing angle which is most commonly seen on laptops. The viewing angle affects the number of people who are able to easily see the screen as it is meant to be seen.

Computer monitors have several design specifications that customer can choose from when purchasing a monitor for their computer. The resolution is one of the most important specifications. This is the horizontal and vertical size of the screen expressed in pixels such as 1024 x 768.

Other specifications include the response time, which is the minimum amount of time needed to change a pixel’s colour or brightness; the colour support which is how many types of colours are supported by the screen; brightness which is the amount of light emitted from the display device (and is more specifically known as luminance) and the aspect ratio which is the ratio of the horizontal size to the vertical size such as 4:3 or 16:10.

Some computer users have more than one monitor set up to their computer which can operate in several modes. The most common setup for multiple monitors is to have the entire desktop spread over all of the monitors which therefore acts as one massive desktop.

Computer display monitors can encounter problems, the most common of which include dead pixels and phosphor burn in. Dead pixels are pixels within the monitor which are not lit up or stuck on a certain colour; red, green or blue. This can sometimes be fixed by running a program which flashes many different colours at high speed in an attempt to reconfigure the dead pixel. Phosphor burn in occurs when a static picture is left on a screen for a long period of time and actually becomes embedded in the phosphor that coats the screen. This doesn’t occur on LCD screens as they don’t have a phosphor coating.

The most common manufacturers of computer display monitors include Casio, Epson, Fujitsu, HP, Panasonic, Samsung, Sharp, Sony, Toshiba and Xerox.
