DELL P2722HE (01) PDF Document

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 like the DELL P2722HE. Once installed, DDM runs each time the system starts and places its icon in the notification tray.

Dell Display Manager uses the DDC/CI (Display Data Channel/Command Interface) channel to communicate with your monitor. You must ensure DDC/CI is enabled in the monitor’s On-Screen Display (OSD) menu. Navigate to ‘Others’ in the OSD menu and set DDC/CI to ‘On’.

Clicking the Dell Display Manager icon in the notification tray opens the Quick Settings dialog box. This dialog allows you to easily adjust the brightness, contrast, resolution, and window layout. You can select ‘Manual Mode’ or ‘Auto Mode’, and change the screen resolution. The dialog also provides access to DDM’s advanced user interface for other features.

You can select ‘Manual Mode’ to manually choose 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 Brightness and Contrast of your DELL P2722HE can also be directly adjusted from the ‘Basic’ tab in DDM.

When multiple Dell monitors are connected, select “Enable display matrix control” on the Basic tab of Dell Display Manager to apply brightness, contrast and color preset controls to all monitors simultaneously.

The ‘Auto Mode’ tab in DDM allows you to associate a specific Preset Mode with a specific application. When Auto Mode is enabled, DDM automatically switches to the corresponding Preset Mode whenever the associated application is activated. 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 configure the Game preset mode to be used whenever a Direct3D application runs in full-screen mode. To prevent an application from using this mode, assign a different preset mode to it.

Easy Arrange helps you organize your application windows on the desktop. First, choose a pre-defined layout pattern that suits your work. Then, drag the application windows into the defined zones. Press “>” or use the Page Up/Page Down key to find more layouts.

To create a custom layout, right-click on the thumbnail with a tiny triangle at the bottom right corner, arrange the numbers of rows and columns in the open window, and then click OK to set up your preferred arrangement.

If you often use the Windows snap feature, you can select “Hold down the SHIFT key to enable zone positioning” in the Easy Arrange settings. 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. To enable this feature, select “Span multiple monitors”. You need to align your monitors properly to make it effective.

The ‘Input Manager’ tab in Dell Display Manager provides ways to manage multiple video inputs connected to your DELL P2722HE. This makes it easy to switch between inputs while working with multiple computers. All available video input ports are listed. You can give each input a name and save your changes. You can also define a shortcut key to quickly switch to your favorite input and another shortcut key to switch between two inputs if you often work between them.

Yes, DDM communicates with your DELL P2722HE monitor even when the monitor is displaying video from another computer. You can install DDM on the PC you frequently use and control input switching from it. You may also install DDM on other PCs connected to the monitor.

DDM can help you restore application windows into their positions when you reconnect your PC to your DELL P2722HE. You can quickly access this feature by right-clicking on the 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 PC to your monitor(s).

NOTE: You should keep your applications running in order to benefit from this feature. DDM doesn’t launch applications.

To go back to a favorite layout, first right-click the DDM tray icon and select “Save current window layout”. Later, you can select “Restore saved window layout” to apply the saved layout.

For Windows 10, you can add the DDM shortcut icon to the toolbar region of active windows. To activate this feature, right-click on the DDM icon in the notification tray and choose ‘Attach to active window’ from the opened menu. Once you right-click the icon in the toolbar, a quick menu of DDM appears, displaying options under Auto Mode and Easy Arrange for you to easily make adjustments.

The ‘Options’ tab in DDM provides PowerNap energy conservation options. In the upper pane, 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.

You can define the shortcut keys for quick access to the following DDM functions:

• Program shortcut key: to quickly open the Quick Settings dialog box.

• Easy Arrange MRU shortcut key: to quickly apply the 5 recently used window layouts.

• Application window shortcut key: to launch a quick menu for options under Auto Mode and Easy Arrange.

If DDM is unable to detect and/or communicate with a supported Dell monitor, please take the below actions to troubleshoot:

1. Make sure the video cable is properly connected to your monitor and your PC, especially the connectors should be firmly inserted into position.

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

3. Make sure you have the correct and latest display driver from the graphics vendor (Intel, AMD, NVIDIA, etc.). Display driver is often the cause of DDM failure.

4. Remove any docking stations or cable extenders or 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 device if the latest version is available.

5. Restart your system.

DDM may not work with the following monitors:

• Dell monitor models earlier than year 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 may require disabling MST/DP 1.2 using the monitor OSD.

If your PC is connected to the Internet, you will be prompted with a message when a newer version of DDM application is available. It is recommended to download and install the latest DDM application.

You may also check for a new version by right clicking on DDM icon while pressing and holding the ‘shift’ key and selecting “Check for new version…” from the menu.
