Monitors

Use Monitor Preferences to configure the monitors that your computer uses.

On most laptop keyboards, you can use the key combination Fn+F7 to cycle between several typical monitor configurations without starting Monitor Preferences.

Drag the graphical representations of the monitors in the upper left part of the window to set how your monitors are arranged. Monitor Preferences displays small labels in the top left corner of each monitor to help you identify which rectangle corresponds to which monitor.

Changes you make in Monitor Preferences don't take effect until you click the Apply button. Settings will revert to their previous settings unless you confirm the changes. This is to prevent bad display settings from rendering your computer unusable.

Same image in all monitors: When this option is selected, your entire desktop will fit on a single monitor, and every monitor will show the same copy of your desktop. When it is not selected, your desktop spans multiple monitors, and each monitor shows only a part of your entire desktop.
Detect monitors: Click this button to find monitors that have been recently added or plugged in.
Show monitors in panel: When this option is selected, an icon will be placed on your panel allowing you to quickly change certain settings without opening Monitor Preferences.

The following list explains the options you can set for each monitor. The currently selected monitor is the one whose graphical representation has a bold black outline. It is also indicated by the background color of the section label.

On / Off: Individual monitors can be completely disabled by selecting Off.
Разрешение: Select the resolution to use for the currently selected monitor from the drop-down list. Resolution refers to the pixel dimensions of the screen. A larger resolution means that more things fit on the screen, but everything will be smaller.
Частота обновления: Select the refresh rate to use for the currently selected monitor from the drop-down list. The refresh rate determines how often the computer redraws the screen. A too low refresh rate (below 60) makes the monitor flicker and can cause discomfort to your eyes. This is less of a problem on LCD displays.
Rotation: Select the rotation for the currently selected monitor. This option may not be supported on all graphics cards.
