A computer monitor or simply monitor is used as a display device for output of the data that is processed by a computer system. The display shows up in pictorial form. Display devices have gone through a sea change over the course of history.
Modern display devices are majorly created using a technology known as thin film transistor – liquid crystal display or TFT-LCD, with LED (Light emitting diode) based technology. This technology has completely swept the market.
Monitors come in an array of display aspect ratios. The most popular being 16:9, which is the current favorite. Though wider perspective ratios are being developed such as 21:9 and even 32:9.
For practical purposes, though 16:9 is suitable for all computing, editing, gaming and entertainment purposes and 21:9 is ideal for gaming and video editing purposes. Apart from resolution, there are several other parameters to buying a monitor.
