A computer monitor or the Visual Display Unit is a very important part in a computer. This is where the displaying of images, data etc from the computer is done. There are various types of computer displays available in the market nowadays. Apart from the CRT displays that used to be the most used until few years back, there are Flat Panels and LCDs that are available now.
There are quite a few things to be considered before buying a computer monitor. The size is one of the factors to be considered. Sizes come from 15", 17", 19" and 21". The larger the display size, the greater the expense. A 17" is ideal where the computer is used for a considerable amount of time of more than 2 hours. For graphics art and such things, the monitor required should be 21" as it would prove useful. One thing to be noted is that even though the size of the screen could be 15", 17" etc the viewable size need not be the same. It would be definitely less than that, according to the manufacturer.
The resolution is the next thing to be considered. This is the clarity with which the picture is seen in a computer monitor. This can depend on the size of the monitor. The resolution is measured in Pixel counts. It is required to be cautious while following the ads from the manufacturers as they might give ads that are impossible to happen, for example a resolution of 1600x1200p for a 15" monitor! The ideal resolutions for a 15" screen is 800x600 or 1024x768, for a 17" screen 1280x1024, 19" screen 1280x1024 and for 21"screen 1600x1200. This is the maximum of resolution capacity by the respective dimensions.
The refresh rate also has to be considered while buying a screen. This is the number of times the screen is redrawn. The recommended refresh rate comes to 75MHz, for a standard monitor. The controls are the next thing to be noticed. Controls are the way the different aspects or features of the computer are controlled. Adjustment of different features of the monitor has to be possible, for strain-free watching and working.
