Softphone.Pro on multiple monitors with different DPI settings

You can use Softphone.Pro on a computer that has multiple monitors connected to it. If those monitors have different DPI settings, you may encounter interface issues as you move the app window between monitors.

You can change the way operating system scales application window when moving it by using dpiawareness parameter.

There are two options to set this parameter:

  • Modify Softphone.Pro shortcut. Fixes the issue when starting Softphone.Pro with modified shortcut only.
  • Add qt.conf file.

Modify Softphone.Pro shortcut

1. Exit Softphone.Pro.

2. Find on your desktop the Softphone.Pro shortcut, right-click it and choose Properties.

3. In the Target field add space after SoftphonePro.exe and type -platform windows:dpiawareness=1.

4. Press OK and launch modified shortcut. Check window's behavior as you move it between monitors.

If the window still scales incorrectly, use the value dpiawareness=0, and see if that fixes the issue. You might see the blurry app window using this parameter value.
