您可以通过P/Invoke使Windows窗体DPI感知，方法是调用SetProcessDPIAware function：

Add-Type -AssemblyName System.Windows.Forms
Add-Type -TypeDefinition '
public class DPIAware {
    [System.Runtime.InteropServices.DllImport("user32.dll")]
    public static extern bool SetProcessDPIAware();
}
'

[System.Windows.Forms.Application]::EnableVisualStyles()
[void] [DPIAware]::SetProcessDPIAware()

$form = [System.Windows.Forms.Form]@{
    Width  = 960
    Height = 540
}
$form.ShowDialog()

如果您想要调用MS文档中推荐的 * 较新 * 函数SetProcessDpiAwarenessContext，但请注意，此函数从Windows 10版本1607开始兼容，以下是实现的外观：

Add-Type -TypeDefinition '
using System;
using System.ComponentModel;
using System.Runtime.InteropServices;

public class DPIAware {
    public static readonly IntPtr UNAWARE              = (IntPtr) (-1);
    public static readonly IntPtr SYSTEM_AWARE         = (IntPtr) (-2);
    public static readonly IntPtr PER_MONITOR_AWARE    = (IntPtr) (-3);
    public static readonly IntPtr PER_MONITOR_AWARE_V2 = (IntPtr) (-4);
    public static readonly IntPtr UNAWARE_GDISCALED    = (IntPtr) (-5);

    [DllImport("user32.dll", EntryPoint = "SetProcessDpiAwarenessContext", SetLastError = true)]
    private static extern bool NativeSetProcessDpiAwarenessContext(IntPtr Value);

    public static void SetProcessDpiAwarenessContext(IntPtr Value) {
        if (!NativeSetProcessDpiAwarenessContext(Value)) {
            throw new Win32Exception();
        }
    }
}
'

[DPIAware]::SetProcessDpiAwarenessContext([DPIAware]::PER_MONITOR_AWARE_V2)
