Monitor, Display Adapters

Displays are used to display visual data to a user, this may be images or video but typically used in computers for graphical user interfaces to make using the computer simpler.

There are three different types of displays.
 * Monochrome – Displays only two colours typically black and white.


 * Grey-Scale – This is similar to monochrome but has different shades. White-grey-Black.

The resolution of a monitor defines how many pixels are addressable on the display, typically by adding more pixels to a display you will increase the sharpness of the image displayed. With physically large displays sizes you need higher resolutions as it becomes easier to identify individual pixels if the resolution is too low or the screen size.
 * Colour – Capable of display thousands of different colours by using three primary colours also known as RGB displays. Red Green Blue.

Refresh rate is another part of the display, it indicates how often the image on the display is updated, however this means to keep a constant refresh rate the hardware in the monitor must be capable of processing the input and updating the entire display fast enough to avoid noticeable stuttering.
