Monitor screen size is measured diagonally across the screen, in inches. Not all of the screen area may be usable for image display, so the viewable area is also specified.
The resolution of the monitor is the maximum number of pixels it can display horizontally and vertically (ie. 800 x 600, or 1024 x 768, or 1600 x 1200).
Pixels (picture elements) are the small dots that make of the image on the screen. The spacing of the screen’s tiny phosphor dots is called the dot pitch (dp), typically .28 or .26 (measured in millimeters). A screen with a smaller dot pitch produces sharper images.
