Can't a remote APP using AxMsRdpClient11NotSafeForScripting be moved to a 2nd left screen with different scale?

Question

In my .NET Framework 4.8 project, I am using the class AxMsRdpClient11NotSafeForScripting from the AxMSTSCLib library to open a remote app. I have a second screen on the left where I can't drag the app to. I can only move it if the two screens have the same scale or if the second screen is located on the right side. Is there a way it could work on the left side and with different scales?I have tried the following:

1. I have changed this:

rdpclient.DesktopWidth = System.Windows.Forms.SystemInformation.PrimaryMonitorSize.Width
rdpclient.DesktopHeight = System.Windows.Forms.SystemInformation.PrimaryMonitorSize.Height

To this:

rdpclient.DesktopWidth = System.Windows.Forms.SystemInformation.VirtualScreen.Width
rdpclient.DesktopHeight = System.Windows.Forms.SystemInformation.VirtualScreen.Height

And this:

rdpclient.DesktopWidth = ClientRectangle.Width
rdpclient.DesktopHeight = ClientRectangle.Height

1. In app.config, I added:

  <windowsSettings>
  	<application>
  		<dpiAware>true/PM</dpiAware>
  	</application>
  </windowsSettings>

1. In the app.manifest file I added:

<windowsSettings>
	<dpiAware>true/PM</dpiAware>
</windowsSettings>		

Nothing worked.

Hi @Arnau Pla,

Try setting the Per-Monitor and Per-Monitor (V2) DPI Awareness.

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
      <dpiAware>true/PM</dpiAware>
      <dpiAwareness>PerMonitorV2</dpiAwareness>
    </windowsSettings>
  </application>
</assembly>

Best Regards.

Hi @Jiachen Li-MSFT ,

Thank you for answering. I have tried it, but it hasn't solved it. Are you sure it is not a bug? I say that because it works well except for this very specific case.
