Set screen resolution on unattended mode

In some scenarios, Power Automate may run unattended flows in a lower resolution than the one used to develop the flows. As a result, some UI elements could be hidden from the screen and cause flows to fail.

To change the resolution in which unattended flows are run:

  1. Navigate to C:\Program Files (x86)\Power Automate Desktop and open the UIFlowService.exe.config file.

  2. Set the value of the Microsoft.Flow.RPA.UIFlowService.ScreenDefaultResolutionEnabled key to true.

    <add key="Microsoft.Flow.RPA.UIFlowService.ScreenDefaultResolutionEnabled" value="true" />
  3. Change the values of the following keys to the proper screen resolution width, height, and scale, respectively. The following code sets the default resolution to 1920 x 1080 pixels.

    <add key="Microsoft.Flow.RPA.UIFlowService.ScreenDefaultResolutionWidth" value="1920" />
    <add key="Microsoft.Flow.RPA.UIFlowService.ScreenDefaultResolutionHeight" value="1080" />
    <add key="Microsoft.Flow.RPA.UIFlowService.ScreenDefaultResolutionScale" value="100" />

  4. Restart your machine.

    Alternatively to restarting your machine, you can restart the UIFlowService service. To restart the service, launch Windows Task Manager, navigate to the Services tab, right-click on the UIFlowService service, and select Restart.
