How Can I Configure My Applications for Optimal High DPI Display Settings?

Optimize application configuration of high DPI display settings: detailed guidelines

High DPI (number per inch) settings of modern display can improve the visual experience. However, applications may encounter problems when rendering text and keeping a clear appearance at a higher resolution. This guide provides a comprehensive plan to solve these problems.

Windows uses different zoom methods at more than 100%DPI. To achieve custom DPI processing, it is necessary to add

to the application list to explicitly enable "DPI virtualization".

<dpiaware> Add DPI list

Create a new XML file called "App.manifest" in the project directory.

Use the following content editing list:
Pinvoke method in the c#

<code class="language-xml"><?xml version="1.0" encoding="utf-8"?>
<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
  <assemblyIdentity name="MyApplication.app" version="1.0.0.0"/>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
        <requestedExecutionLevel level="asInvoker" uiAccess="false"/>
      </requestedPrivileges>
    </security>
  </trustInfo>
  <application>
    <windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">
      <dpiAware>true</dpiAware>
    </windowsSettings>
  </application>
</assembly></code>

or, you can use the function in C#for programming control:

Visual Studio 2015 and above versions SetProcessDPIAware()

<code class="language-csharp">[STAThread]
static void Main() {
    if (Environment.OSVersion.Version.Major >= 6) SetProcessDPIAware();
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new Form1());             // 根据需要修改
}

[System.Runtime.InteropServices.DllImport("user32.dll")]
private static extern bool SetProcessDPIAware();</code>

For projects that target Visual Studio 2015 UPDATE 1 or higher versions, the list has included the necessary DPI processing instructions. Just delete the comment to activate it.
