The Purpose of a Monitor

The overall purpose of a great computer monitor is to display visual information that has been fed to it by a computer’s video card. This allows those who are using the computer to make decisions based on visual data. Beyond this, computer monitors offer a number of specialized uses and there are many types of computer monitors to select.

Various Uses of Computer Monitors

Computer monitors can be used in a number of different ways to suit the needs of a wide variety of general consumers. Displays can be accessed by professionals or garden variety users.


One of the primary uses of computer monitors and 3D computer monitors is for gaming. Modern gamers are always looking toward the latest display innovation to help them gain a competitive edge or just to improve overall immersion. Those shopping for a high-quality gaming monitor will want to consider the refresh rate, as a higher refresh rate will translate to a seamless gaming experience. We would recommend serious gamers opt for a refresh rate of at least 120Hz, though casual gamers can get by with 75Hz. Gamers should also demand a speedy response time, to cut down on lag.

Business Users

Large corporations and businesses were among the earliest adopters of computer monitor technologies, as displays were prohibitively expensive when first released. Modern business-centric software applications, such as Microsoft Excel, have continued this trend. Computer displays are necessary to trade stocks, plan meetings, keep track of inventory, and much more. Best of all, business applications do not typically require beefy specs, as just about any monitor should work. Computing power, however, may be something of a bottleneck in this regard.
