Overview Dell Display Manager (DDM) is a Microsoft Windows application used to manage a monitor or a group of monitors. It allows manual adjustment of the displayed image, assignment of automatic settings, energy management, window organization, image rotation, and other features on select Dell monitors. Once installed, Dell Display Manager runs each time the system starts and places its icon in the notification tray.

When more than one supported Dell monitors are connected to the computer, a specific target monitor can be selected using the menu. The Quick Settings dialog box enables you to easily adjust the brightness, contrast, resolution, window layout, and so on. You can select Manual Mode or Auto Mode, and the screen resolution can be changed.

The Preset Mode assigned to a particular application may be the same on each connected monitor, or it can vary from one monitor to another.

Press “>” or use Page Up/Page Down key to find more layouts.
For Windows 10, you can apply different window layouts for each of the virtual desktops. If you often use Windows snap feature, you can select “Hold down the SHIFT key to enable zone positioning”. This gives Windows snap priority over Easy Arrange. You will then need to press the Shift key to use Easy Arrange positioning.
