Computer displays show on screen what is going on in the computer. Along with the input devices (mouse and keyboard), the display is among the most important parts of the computer to learn about. Diplays are often called "monitors", or "screens" interchangably.

Displays are mainly of two types (CRTs) which are big like a television, or flat-panel displays (typically LCD) which are much thinner and lighter.

The screen is made up of tiny dots called "pixels" which change color according to instructions sent by the computer. Mainly you look at the display and use it to interact with the computer, but occasionally you may need to consider how they work.

The size of the image shown screen and the amount of pixels used to create that image have an inverse relationship. These settings are configurable, and are used to fine-tune the user's experience. The main thing that users do is change the amount of pixels visible (making the image bigger vs. smaller) and inversely affecting the amount of detail visiable.

These trade-offs become very intuitive over time, but can be confusing to novice users. The thing to remember is that if you are unhappy with the size or detail of what is on screen, chances are there is a way to change the display settings to address this.
