Screen size – the viewing area, measured diagonally in inches.
Resolution – the clarity of the image depending on the number of pixels
(separate units of light) on a display across and down the screen. The sharpness of an image is
affected by dot pitch – the distance between the pixels. Most monitors offer 0.25 mm
dot pitch. The higher the resolution the more pixels are used which takes up more storage space in the
computer. A typical resolution is 1024x768.
Brightness – the amount of light the monitor produces, measured in cd/m2 (candela per square metre).
Aspect ratio – the width of the screen to the height (4:3, 16:9).
Colour depth – the number of colours which a monitor can display.
Refresh rate – the number of times that the image is drawn each second. If the
rate is low, you can notice a flicker. The refresh rate should be at least 72 Hz.
