# 2.1 Introduction

A particular X server, together with its screens and input devices, is called a display. The CLX display object contains all the information about the particular display and its screens, as well as the state that is needed to communicate with the display over a particular connection.

Before your program can use a display, you must establish a connection to the X server driving your display. Once you have established a connection, you then can use the CLX macros and functions discussed in this section to return information about the display. This section discusses how to:

- Open (connect) a display
- Obtain information about a display
- Access and change display attributes
- Close (disconnect) a display
