Overview Dell Display Manager is a Windows application used to manage a display or a group of displays. It allows manual adjustment of the displayed image, assignment of automatic settings, energy management, window organization, image rotation, and other features on select Dell displays. Once installed, Dell display manager runs each time the computer starts and its icon is placed in the notification tray.
Using the Quick Settings Dialog Clicking Dell Display Manager’s notification tray icon opens the Quick Settings dialog box. When more than one supported Dell model is connected to the system, a specific target display can be selected using the menu provided. The Quick Settings dialog box allows convenient adjustment of the display’s brightness and contrast levels. You can manually select a preset mode or enable automatic selection of a preset mode depending on the active application.
Setting Basic Display Functions A preset mode for the selected display can be manually applied using the menu on the Basic tab. Alternatively, Auto Mode can be enabled. Auto Mode causes your preferred preset mode to be applied automatically when specific applications are active. A message momentarily appears on the screen showing the selected preset mode. The selected display’s brightness and contrast can also be directly adjusted from the Basic tab.
Assigning Preset Modes to Applications The Auto Mode tab allows you to associate a specific preset mode with a specific application, and apply it automatically. When Auto Mode is enabled, Dell Display Manager automatically switches to the corresponding preset mode whenever the associated application is activated. The preset mode assigned to a particular application may be the same on each connected display, or it can vary from one display to the next.
Organizing Windows with Easy Arrange Some Dell models feature Easy Arrange, which allows the selected display’s desktop to be organized into various predefined or custom window layouts. When Easy Arrange is enabled, windows can easily be repositioned and resized automatically to fill specific regions within a window layout. To get started with Easy Arrange, choose a target display and select one of the predefined layouts. The regions for that layout are displayed momentarily on the display.
To use the custom layout, select the custom layout icon. To delete the currently saved custom layout, close all windows on the desktop and then click the Save link in Easy Arrange.
Managing Multiple Video Inputs The Input Manager tab provides convenient ways for you to manage multiple video inputs connected to your Dell monitor. It makes it very easy to switch between inputs while you work with multiple computers. All video input ports available to your monitor are listed. You can give each input a name as you like. Please save your changes after editing.
NOTE: DDM communicates with your monitor even when the monitor is displaying video from another computer. You can install DDM on the computer you frequently use and control input switching from it. You may also install DDM on other computers connected to the monitor.
Applying Energy Conservation Features On supported Dell models, an Options tab is available to provide PowerNap energy conservation options. When the screensaver activates, the display’s Brightness can automatically be set to minimum level or the display can be put to sleep in order to save additional power.
Restoring Application Positions DDM can help you restore application windows into their positions when you reconnect your computer to the monitor(s). You can quickly access to this feature by right-clicking on DDM icon in the notification tray. If you choose “Auto-restore window layout”, your application windows’ positions are tracked and remembered by DDM. DDM automatically puts the application windows into their original positions when you reconnect your computer to your monitor(s).
Troubleshooting If DDM cannot work with your display, DDM will show below icon in your notification tray. Click on the icon, DDM shows a more detailed error message. Please note that DDM only works with Dell branded displays. If you are using displays from other manufacturers, DDM doesn’t support them.
