Monitor measurements indicate the monitor's diagonal length. Larger monitors tend to be more expensive. The size of the monitor determines the pixel density for the monitor resolution. Larger monitors are able to accommodate higher resolutions, leading to a higher quality image.
Monitors that have 22- or 23-inch screens and above are able to use a full high definition resolution. Monitors of these sizes also typically have more features, such as HDMI ports, than smaller monitors.

Users who watch movies or play video games on their computers benefit from high quality monitors, but those who only use computers for basic tasks are better off saving money.Learn more about Computers & Hardware
