computer users could not see the work they are performing

3. Different Types of Monitors

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 space, 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.
