客户的 IT 管理员要求我“编写一个 powershell 脚本,在启动时手动设置分辨率”。如果他们要求我这样做,我想这是可能的。我对 powershell 完全没有经验。我的脚本/命令及其错误如下:
Set-DisplayResolution -Width 1024 -Height 768
Set-DisplayResolution
不被识别为 cmdlet、函数、脚本文件或可运行程序的名称。
Set-ScreenResolution -Width 1024 -Height 768
Set-ScreenResolution
不被识别为 cmdlet、函数、脚本文件或可运行程序的名称。
SetDisplayResolution -Width 1024 -Height 768
SetDisplayResolution
不被识别为 cmdlet、函数、脚本文件或可运行程序的名称。
我遗漏了什么?谢谢。

答案2
您需要安装显示设置来自 Powershell-Gallery 的模块来获取此功能。
模块安装
Install-Module -Name DisplaySettings
用法
Set-DisplayResolution -Width 800 -Height 600
答案3
创建一个 setResolution.ps1 文件,其内容如下(src):
Function Set-ScreenResolution {
<#
.Synopsis
Sets the Screen Resolution of the primary monitor
.Description
Uses Pinvoke and ChangeDisplaySettings Win32API to make the change
.Example
Set-ScreenResolution -Width 1024 -Height 768
#>
param (
[Parameter(Mandatory=$true,
Position = 0)]
[int]
$Width,
[Parameter(Mandatory=$true,
Position = 1)]
[int]
$Height
)

然后可以从 powershell 执行该文件,如下所示
`C:\path-to-file\setResolution.ps1`
答案4
Albin 帖子中的 powershell 脚本运行正常 - 但在一台机器上只允许我设置 1920x1080,而不能设置 1920x1200,我可以手动设置。最后我不得不使用 Nirsoft MultiMonitor,它允许您保存和加载配置文件。我可以编辑配置文件并输入分辨率参数,它运行得很好。配置文件如下所示:
Name=\\.\DISPLAY1
Width=1920
Height=1200
虽然我尽可能避免使用第三方工具,但这次它是免费的、轻量级的并且运行良好(并且没有任何病毒)......
