Get it from Microsoft

Click “Get it from Microsoft” to see Display Changer X (also known as DisplayChangerX) in the Microsoft Store. You can try Display Changer X before purchasing. After purchase, you will receive ten licenses and free, automatic updates.

Display Changer X is also perfect for organizations that need to configure their employees’ computers. The configuration files created by Display Changer X on one machine can be copied to other machines with the same model of monitors. (If the monitors are the same model, however, portability is not guaranteed.)

Enterprise customers: If you do not see what you need, please contact Sales.

Display Changer X saves your custom display settings to its own configuration file (DCX), and you apply a configuration by just double-clicking (or invoking from the command line) the desired configuration file. This saves you time and hassle, as you won’t have to manually change your display settings every time you switch between different activities. You can also place a shortcut to a DCX configuration file in your Windows Startup folder to apply a specific configuration when you log in.

Display Changer X creates a configuration file from the current settings, which eliminates the need for you to edit the files yourself while also verifying that the configuration is valid. Each configuration file stores every setting for each monitor, including the very precise refresh rates needed for home-theater systems.

Change the resolution of any Windows display (width, height, color depth, refresh rate, scaling, and rotation) permanently or only while a specific application is running. Display Changer X can also clone (duplicate), extend, add, detach, and rearrange the displays in a multiple-monitor setup. This is useful for presentations with laptops as well as games and home-theater computers.

Display Changer X can run another application in a specific display resolution and return to the previous resolution when the application finishes. This is very useful if you want to run a specific application in a different configuration (e.g., a larger or smaller resolution) temporarily.

Display Changer X can change the resolution permanently and rearrange the monitors in a multiple-monitor setup. It can also duplicate (clone) your monitors, extend the desktop to multiple monitors, configure only the primary PC screen, and configure only the secondary screen.

Screen sharing using Teams on Ultrawide Monitors

Display Changer X can only apply settings that can be configured in Windows Display settings. It cannot apply driver-specific settings that are available in custom applications, such as AMD, nVidia, and Intel.

In addition, Display Changer X cannot be used to apply some configurations to others in the same way that Windows Display settings cannot. First, an intermediate configuration must be applied. For example, when a single monitor is active, Windows Display settings cannot activate and clone two additional monitors. First, at least one of them must be added to the configuration by extending the primary display. Display Changer X shares this limitation.

Example 1: When applying a clone configuration on a non-clone configuration, at least one of the future cloned monitors must be active in the configuration. For example, if you want to go from a 1 configuration to a 1-2|3 configuration (where 2 and 3 are cloned), first you need to apply a 1-2 (or 1-2-3 configuration) in order to activate either Display 2 or 3 (or both). Then, you can apply the 1-2|3 configuration.

Example 2: When applying a non-clone configuration on a clone configuration, all of the cloned monitors must be inactive before you can apply a configuration in which they are active. For example, if you want to go from a 1-2|3 configuration (where 2 and 3 are cloned) to a 1-2 configuration, first you need to apply a 1 configuration in order to deactivate Displays 2 and 3. Then, you can apply the 1 configuration.

Display Changer X cannot modify the Windows DPI (scaling factor) or HDR settings. There is currently no Microsoft API that offers these features. Although some applications hack the Registry to modify the DPI, they require the user to restart Windows, which Display Changer X avoids. If Microsoft does offer these features at some point, I plan to update Display Changer X to take advantage of them.

Display Changer X does not support adding Miracast (Wi-Fi) devices. Windows requires the user to initiate the connection for security reasons, so there is no programmatic way to do this. However, Display Changer X is able to apply a configuration once the Miracast device is connected.


Open Display Changer X when you want to create a new configuration file or to validate an existing one.

Configure Display

The first step is to set up your monitors the way you want them for the new configuration file. Press the Configure Display button to quickly access Windows Display Settings.

Create Configuration File

Press the Create Configuration File… button to create a configuration file that will apply the current display settings.

Optional Application or Document

If you want to open an application or document when this configuration file is applied, tick the “Open application or document after applying configuration” check box.

To select the application (or document) to open after the configuration is applied, press the Browse button.

To select the working folder for the application (or document), press the Browse button.

Finally, you can select another configuration file to apply after the selected application (or document) exits.

Example: An application and command line parameters will be run when this configuration is applied.
Example: A document will be opened when this configuration is applied.

Press the Create Configuration File… button to create a configuration file that will apply the current display settings, open the specified application or document, and (optionally) apply another configuration file.

You can create Windows shortcuts to your configuration files and use them to quickly change to the display configuration you want.


Press the Validate Configuration File… button to select a configuration file and verify that it will work on your system.

If you need to contact 12noon for support, please tick the Save log to desktop check box and validate the configuration file you are experiencing an issue with. This will create a file named Display Changer X.log on your desktop (or append to it if it already exists). Please include it with your support request.

You can also edit the DCX configuration file (using Notepad) and change the trace="false" attribute to true. Now, when you apply that configuration file, it will create a file named Display Changer X.log on your desktop (or append to it if it already exists). Please include it with your support request.

Command Line Usage

Display Changer X creates a Windows app execution alias, so that you can also access it from the command line. You can disable the alias in Windows Settings.

dcx.exe [path to DCX configuration file]

If a configuration file is specified, Display Changer X will apply that configuration.


Display Changer X supports Microsoft® Windows® 11 and 10.
