A CRT monitor

A computer monitor is an electronic device that shows pictures. A monitor is usually used to see programs on a computer. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. A monitor may be used to watch television if it is connected to a device that has a television tuner. Some high definition monitors do have a television, and some televisions are used with computers. A monitor has a better display resolution than a television to make it easier to see smaller letters and graphics on.

There are two main types of monitors :

  • The CRT monitor, which is big and heavy. It is the oldest technology used by monitors. It looks like a television, but has a bigger display resolution and often a higher frequency.
  • The LCD monitor, which is thin, flat, and lightweight. It is a newer technology than CRTs. The quality can be the same or even better than a CRT, but this type of monitor usually costs more than a CRT.
