Dell Display Manager is a Microsoft Windows application used to manage a monitor or a group of monitors. It enables manual adjustment of the displayed image, assignment of automatic settings, energy management, window organization, image rotation, and other features on selected Dell monitors. After installation, Dell Display Manager runs each time the system starts and places its icon in the notification tray.

NOTE: Dell Display Manager uses the DDC/CI channel to communicate with your monitor. Ensure that DDC/CI is enabled in the monitor’s menu.

Click the Dell Display Manager’s notification tray icon to open the Quick Settings dialog box. When more than one supported Dell model is connected to the computer, a specific target monitor can be selected using the menu. The Quick Settings dialog box enables convenient adjustment of the monitor’s brightness and contrast levels. You can select Manual Mode or Auto Mode, and the screen resolution can be changed.

The Quick Settings dialog box also provides access to Dell Display Manager’s advanced user interface that is used to adjust basic functions, configure auto mode and access other features.

You can select Manual Mode, which enables you to manually select a preset mode, or select Auto Mode, which applies a preset mode based on the active application. An on-screen message displays the current preset mode whenever it changes. The selected monitor’s Brightness and Contrast can also be directly adjusted from the Basic tab in the Dell Display Manager.

NOTE: When multiple Dell monitors are connected, select “Enable display matrix control” to apply brightness, contrast and color presets controls to all monitors.

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 monitor, or it can vary from one monitor to another.

To add a new application to the assignment list, simply drag the application from the desktop, Windows Start Menu or elsewhere, and drop it onto the current list.

NOTE: Preset Mode assignments for batch files, scripts, loaders, and non-executable files such as zip archives or packed files, are not supported.

You can also configure the Game preset mode to be used whenever a Direct3D application runs in full-screen mode. To prevent an application from using mode, assign a different preset mode to it.

Easy Arrange helps you to effectively organize your application windows on the desktop. First, choose a pre-defined layout pattern which suits your work, then drag the application windows into the defined zones. Press “>” or use Page Up/Page Down key to find more layouts. To create a custom layout, arrange the open windows and then click Save.

For Windows 10, you can apply different window layouts for each of the virtual desktops.

If you often use the Windows snap feature, select the “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.

If you are using multiple monitors in an array or matrix, the Easy Arrange layout can be applied across all the monitors as one desktop. Select “Span multiple monitors” to enable this feature. You need to align your monitors properly to use it effectively.

The Input Manager tab provides convenient ways for you to manage multiple video inputs connected to your DELL E2420H. It makes it 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. Save your changes after editing.

You can define a shortcut key to quickly switch to your favorite input and another shortcut key to quickly switch between two inputs if you often work between them. You can also use the dropdown list to switch to any available input source.

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.

Yes, Dell Display Manager (DDM) can help you restore application windows into their positions when you reconnect your computer to the monitor(s). You can quickly access this feature by right-clicking on the DDM icon in the notification tray.

Auto-restore window layout: If you choose this option, your application windows’ positions are tracked and remembered by DDM. DDM automatically puts the application windows into their original positions when you reconnect your PC to your monitor(s).

Save and Restore layout: If you want to go back to a favorite layout after you have moved the application windows around, you can first “Save current window layout” and later “Restore saved window layout”.

DDM is able to know the monitor you have reconnected and restore application positions accordingly, even if you use monitors with different models or resolutions.

NOTE: You should keep your applications running in order to benefit from this feature. DDM does not launch applications.

On supported Dell models like the DELL E2420H, an Options tab is available that provides PowerNap energy conservation options. You can choose to set the monitor’s brightness to the minimum level, or to put the monitor to sleep when the screensaver is activated.

If DDM does not work with your monitor, it will show an icon in your notification tray indicating “Please connect a supported Dell monitor”. Clicking the icon shows a more detailed error message. Please note that DDM only works with Dell branded monitors. If DDM is unable to detect and/or communicate with a supported Dell monitor, please take the following actions to troubleshoot:

1. Make sure the video cable is properly connected between your monitor and your computer. Ensure the connectors are firmly inserted into position.

2. Check the monitor OSD to ensure DDC/CI is enabled.

3. Make sure you have the right graphics card driver from the vendor (Intel, AMD, NVIDIA, etc.). The graphics driver is often the cause of DDM failure.

4. Remove any docking stations, cable extenders, and converters between the monitor and the graphics port. Some low-cost extenders, hubs, or converters may not support DDC/CI properly and can fail DDM. Update the driver of such a device if the latest version is available.

5. Restart your computer.

DDM may not work with the following monitors:

Dell monitor models that shipped earlier than 2013 and D-series of Dell monitors.

Gaming monitors using Nvidia-based G-sync technology.

Virtual and wireless displays do not support DDC/CI.

Some early models of DP 1.2 monitors; it may be necessary to disable MST/DP 1.2 using the monitor OSD.
