我试图通过脚本（Powershell）设置屏幕分辨率。
我找到了cmdlet Set-DisplayResolution，它应该适用于Server 2012 / R2和8 / 8.1（它不会工作），而且它也无法在Windows 10 PS 5.0上运行。
我也看过
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Screen]::AllScreens
和
[System.Windows.Forms.Screen]::PrimaryScreen
但它显示了奇怪的输出：
BitsPerPixel : 32
Bounds : {X=0,Y=0,Width=2000,Height=1333}
DeviceName : \\.\DISPLAY1
Primary : True
WorkingArea : {X=0,Y=0,Width=2000,Height=1293}
我运行的是3000x2000分辨率。即使我将显示器更改为1920x1080，输出也保持不变。
经过长时间的搜索后，我找到this script，它使用win32 API完成工作。有没有更方便的方法来执行此操作，因为此Set-DisplayResolution只是在Windows 10安装上运行？
我还想设置Windows 10的UI缩放（如150％）。
当然，我想知道为什么AllScreens的{{1}}和PrimaryScreen方法无法正常运作。

很抱歉告诉你，但是对于powershell来说是不可能的：
[System.Windows.Forms.Screen] - 命名空间表示您需要了解的全部内容：此命名空间引用您编码为Windows窗体的应用程序的显示区域（如果您需要更改窗口，则有用） - 申请中的大小）
Cmdlet Set-Displayresolution仅适用于Windows Server 2016 Core（或将来的任何其他Core-Server）。它记录在Technet上：https://technet.microsoft.com/de-de/library/jj603036(v=wps.630).aspx
使用前面找到的Win32-API的解决方法看起来是您可以获得的最佳解决方案。

请参考以下脚本以更改Windows 10上的显示分辨率。Windows 10不支持PowerShell服务器核心。您可以使用以下脚本 重要：您可以在脚本末尾提供显示分辨率 当前将其设置为Set-ScreenResolution -Width 1920 -Height1080。您可以更改这些值。复制此完整脚本并另存为Set-ScreenResolution.ps1，然后使用PowerShell执行。确保以管理员身份运行powershell

有点晚了，但根据您需要的分辨率设置，您可以使用AHK（脚本语言）。这将需要一个脚本打开显示设置对话框并向其发送点击或击键。如果您有兴趣，我可以提供更多信息
更新： 首先，您必须在计算机上安装AutoHotKey（这对于Google来说非常简单）。接下来，使用脚本将键盘输入发送到控制面板显示设置。它可能看起来像这样：
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
