The monitor is the part of the computer we are always watching at and the eyes are most the sensitive organs we use while working with a computer. Therefore when buying a computer the best thing to do is spend at least one third of the budget on a good and reliable monitor. Moreover as technology develops the price of appropriate monitors is becoming even affordable, for example, two years ago it was a luxury for anyone to buy a 17 inches monitor, today it is almost essential to use a 17 inches monitor especially in the multimedia sector. Furthermore in today’s market we found a large amount of supply and diversity, monitors basically can be classified in three types of display technology: Cathode Ray Tube (CRT), Liquid Crystal Display (LCD, usually in laptops or notebooks) and Flat screen (professional use, very expensive for home or personal use). Monitors can also be classified by size; here is a table of the most common monitor sizes together with the viewing area, resolution and the frequency needed. The majority of monitors are based on Cathode Ray Tube (CRT) technology. These are cheap and reliable. The CRT technology has been deeply evolved and CRTs offer a reasonable high quality of colour images on desktop computers together with low costs. The size usually varies from 15” to 17”. Although curves screens distort the image and the screen reflections that may happen with CRTs cause eyestrain. CRTs are not very high in resolution and they take a lot of space in your workplace. The main technology that is more likely to be used from now on is the Liquid Crystal Display (LCD) technology, which are so familiar to us in Laptop computers and in electronic notebooks. Some manufactures are expecting colour Plasma Display Panels (PDPs) to be available in 21” and 23” size range. These are very thin therefore they take less space. LCDs are free of flickers, distortion or reflection and considerably reduce eyestrain, although the manufacturing process is complicated and extremely costly. This technology is set to be the monitor technology of the near future.

All these use of graphics, video and sound have made monitor designers to change the perspective of monitor layout adding speakers, microphones, cameras and so forth to the monitor itself. This also may affect monitor’s prices although the monitor you buy today is not the same as the one you bought last year. Technology and quality items are evolving so rapidly that the prices vary dramatically from one year to another. Most LCDs use digital circuitry and typical monitors support 262,000 (18 bit-256K) colours, whereas CRT monitors support an infinite range of colours within their overall range or gamut colours. For motion video applications the range of colours should be at least 262,000. Some LCDs support a more limited range of colours and are not suitable for multimedia applications. LCDs are very expensive, for intensive work journeys and for professional use mainly; if you are interested in multimedia applications it may not be right choice. Bibliography: Word Count: 648
