Most computer displays are so-called LCD displays (Liquid Crystal Display), where the image display is produced by liquid crystals between two transparent sheets. Display sizes range between only a few inches in handheld apparatuses to large 24 inch desktop displays.
One of the most important features of the display is itsresolution, i.e. how many pixels (picture elements) the image consists of. A normal 22 to 24-inch widescreen display usually has 1920 pixels horizontally and 1200 pixels vertically (1920×1200). These displays can reproduce FullHD (full high definition) image.
No matter what the type of display is, the computer must contain a so-called display adapter that allows you to attach the display to the computer and controls the display image. Practically all motherboards come equipped with a display adapter, so you do not need to buy one separately, unless you want to enhance the capabilities of your desktop computer e.g. for gaming, video editing, or 3D imaging purporses.
