There are many types of computer monitors from which to choose. The ideal monitor for you is probably the model that best suits your needs in terms of video in/outputs, and hdtv and bluray compatibility. Not all computer monitors are created equal. Some computer monitors generate output with the help of cathode ray tubes. This type of device is called the CRT (or, cathode ray tube) monitor. Some computer users prefer this style because it offers a richly colored display and does not break easily. However, CRT monitors can be bulky and take up a lot of desk real estate, be very heavy to carry, and they require a lot of power to run properly. Moreover, the picture screen can distort, display a "flicker effect," or burn out over time.

The newer types of display units are liquid crystal display monitors (or, the LCD monitor) and plasma screen monitors. LCD and plasma screen styles are much lighter than their older CRT counterparts. LCD models in particular require less power to run. However, these newer models can be more expensive than traditional computer monitors, and may be susceptible to screen pixel burnout. Fortunately, as plasma and LCD monitors become more popular, monitor repair options increase.

Monitor size is another factor that will affect your purchasing decision. If you use your computer only for e-mail and reading the news, a smaller monitor might suit you. However, if you have difficulty reading small print, or work in a profession that requires close attention to detail, such as graphic design, a larger monitor is probably your best option.
