Executable is not DPI aware

ID PE142 Level INFO Category System

Description

The executable does not specify the DPI awareness options in the Application manifest. Newer Window-based applications should be PerMonitorV2 DPI aware.

Mitigation

If using Visual C++:

  • Create a separate Application manifest file if you have not done this for your application yet. This file will be used as an additional source to the default manifest generated by the Manifest tool.
  • Add the external manifest file as an additional input file to the Manifest tool (also see the screenshot below).
  • Add the dpiAwareness element to your Application manifest file and declare PerMonitorV2 DPI awareness. See the official Microsoft example.
Adding extra manifest

If using Visual Studio with .NET Console, WinForms, WPF projects:

  • Add the Application manifest file to your project. See the screenshot below.
  • Add the dpiAwareness element to the Application manifest file in your project and declare PerMonitorV2 DPI awareness. See the official Microsoft example.
Adding manifest to C#

Note: in addition to the dpiAwareness element, you can add the dpiAware element to make your application compatible with earlier Windows versions.
