There are several types of monitors similar to a regular television. Flat-screen monitors with enhanced technology make it easier for users to install the device onto their computer. These monitors have replaced old tube screens that take up more space and are harder to install.

The Computer Monitor uses many hardware technologies to display the output. They are :

• Plasma display,

• Video projectors like CRT, LCD, and DLP etc.

• FED (Field Emission Display).

• Vector displays etc.

The performance of the Computer Monitor can be measured using the parameters like luminance, aspect ratios, display resolution, dot pitch, response time, refresh rate and viewing angle. The various problems that take place in the monitor are dead pixels, stuck pixels, glare, incomplete spectrum etc.

The various features with the Computer Monitor are power saving, touch screen, glossy screen and integrated accessories.
