A computer monitor is a piece of computer hardware that shows the video and graphics made by the computer through the video card. A computer monitor is a lot like a television only with higher resolution in its picture quality. Computer monitors used to be made up of a CRT (Cathode Ray Tube) and a fluorescent screen. Now computer monitors are made from flat panel display technology. All monitors regardless of what kind they are all have an HDMI, DVI, or VGA port on a computer.[1][2]


One of the things that shows how good the quality is of a monitor is frequency. The majority of monitors are multiscanning, meaning the monitors adjust to the frequency that is being sent to them. This allows the monitor to display images at different resolutions, based on the data that is sent to the monitor by the video adapter.

Screen Size[]

Screen size is an important attribute to a monitor. The size of the screen is measured in inches from diagonal corners like a television. A VGA monitor is usually 14 inches, some monitors are 16 inches or longer these monitors are known as full-page monitors. Monitors can also be displayed in either portrait or landscape height.

Pixels and Resolution[]

A monitors resolution shows how closely packed the pixels are. In most cases the more pixels shown the sharper the image, usually the pixels are shown in dots per inch. The SVGA standard amount of pixels displayed is 1024 by 768 pixels. The nicer models display 1280 by 1024 or sometimes 1600 by 1200. Most monitors either have analog or digital signal systems. Modern monitors usually use analog signal which is the only signal that the UGA, SVGA, 8514/A and other high resolution color standards use.[3]
