When it comes to purchasing a computer, there are many things to consider. Not only do you need to choose the right operating system, hard drive, and accessories, but you have a wide variety of computer monitors to choose from. Also called visual display units, monitors are an integral part of your computer and should be chosen carefully.
Monitors display images that are generated by computers and they come in all shapes, sizes, and proportions. The size of computer monitors is generally determined by measuring the distance between two opposite corners of the screen. The size of the screen affects the number of pixels and, in many cases, the clarity of picture. In addition to various sizes, monitors come in a variety of types. The most popular type of computer monitor is the liquid crystal display, or LCD. An LCD screen produces an image on a flat surface by projecting light through liquid crystals. The advantage of this type of monitor is that it consumes less power than other types and has lower glare which reduces the eyestrain of viewers.
A more basic type of computer monitor is the cathode ray tube, or CRT. In order to create a picture, the CRT monitor utilizes many rows of tiny colored dots which light up when negatively charged electrons are shot through the tube. The number of dots per inch is referred to as the “resolution” of a CRT monitor; the higher the resolution, the clearer the picture. This type of monitor was used in many older computers but has generally been replaced by newer technologies.
One of the newest technologies available in computer monitors is the plasma screen, most frequently available in the form of a flat screen display. A plasma monitor works by illuminating tiny fluorescent lights to produce color and picture. Plasma monitors offer high contrast ratios and excellent color. They are also typically compact and lightweight, but frequently consume a larger amount of power than other monitors.
In addition to these varieties of computer monitors, several specialized types of monitor are available. Some computers are able to utilize touch screen monitors on which items can be moved with the touch of a finger. This type of monitor eliminates the need for a mouse or touch pad, but it will require frequent cleaning. The tablet screen is a variation on the touch screen, but it is generally unresponsive to the touch of a finger. Rather, this type of monitor requires the pressure of a special tool or device.
When choosing a monitor, there are many options to consider. Along with size and shape, you must decide what type of monitor will suit your needs. By doing a little research before making your purchase, you can ensure that whatever choice you make will leave you satisfied.
