There are two main types of computer monitors present on the market nowadays: the Liquid Crystal type of monitors and the Cathode Ray Tube type. There are numerous and various models that have been presented among the offers of the market. They are all different according to their size, their resolution, their brightness and many other features that characterize them. CRT computer monitors are considered to be the old model, as nowadays many users use LCDs, which are considered innovative and more performant. There are still users who have CRTs and are still satisfied with the way in which it functions. In the end, it all depends on what each user wants and chooses when he or she buys a computer monitor.

These features are taken in account when analyzing both CRT computer monitors and LCDs.

There are users who still consider CRT computer monitors as being very good and do not agree with the fact that LCDs are necessarily much better than the old type. Others in exchange do not even want to hear anymore about the CRT type of computer monitors as they are using LCDs and consider them much improved than the other ones. Among the features which make the Cathode Ray Tube type of computer monitors to be used by some of the users are considered the high contrast ratio, the high seed response, the colors, the low black level, the brightness, the excellent viewing angle and the display technology. Users who still have and work with this type of computer monitors consider them to be very good because of these good features that characterize them.

There are also persons who do not agree with those who still consider CRT computer monitors as a good component for their computers. Among the bad features about the Cathode Ray Tube type of monitors are considered to be the large size, the weight, the geometric distortion, the big warm-up time, the big power consumption, the possible failures which usually happen with them, the high interior voltages, the brightness which cannot reach the maximum value reached by the LCDs and the lower contrast ratio. The opinions are numerous and various related to the performance of CRT computer monitors. In the end, every user chooses what kind of computer monitor to use and why.

CRT computer monitors represent the older type of computer display, but it still presents some features that can even be considered better in comparison with the LCDs. It also presents certain disadvantages, such as the large sizes in which it can be found. It all depends on what each user decides to be most important for him when buying a computer monitor: the size, the resolution, the contrast ratio, the aspect ratio, the luminance, the viewing angle or another important feature. What is important is that we have many offers from which to choose so that each of us might buy the best computer monitor that can help us work easier and properly with our computers.
