Windows 7 在Windows 7中使用WMI/powershell获取屏幕分辨率

我正在使用以下脚本在Windows中使用WMI获得屏幕分辨率。当计算机处于横向模式时，脚本工作正常，但在纵向模式下返回不正确的值。在XP中正常工作，未在Vista中尝试。有人能确认这是Windows7WMI中的错误吗

strComputer = "." 
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2") 
Set colItems = objWMIService.ExecQuery( _
    "SELECT * FROM Win32_DesktopMonitor",,48) 
For Each objItem in colItems 
    Wscript.Echo "-----------------------------------"
    Wscript.Echo "Win32_DesktopMonitor instance"
    Wscript.Echo "-----------------------------------"
    Wscript.Echo "ScreenHeight: " & objItem.ScreenHeight
    Wscript.Echo "ScreenWidth: " & objItem.ScreenWidth
Next

---

请注意，PowerShell代码为：

Get-WmiObject -Class Win32_DesktopMonitor | Select-Object ScreenWidth,ScreenHeight

我在横向或纵向模式下得到相同的值

更新：

在多监视器环境中，您可以通过以下方式获取所有监视器的信息：

PS> Add-Type -AssemblyName System.Windows.Forms
PS> [System.Windows.Forms.Screen]::AllScreens


BitsPerPixel : 32
Bounds       : {X=0,Y=0,Width=1280,Height=800}
DeviceName   : \\.\DISPLAY1
Primary      : True
WorkingArea  : {X=0,Y=0,Width=1280,Height=770}

BitsPerPixel : 32
Bounds       : {X=1280,Y=0,Width=1920,Height=1200}
DeviceName   : \\.\DISPLAY2
Primary      : False
WorkingArea  : {X=1280,Y=0,Width=1920,Height=1170}

您可以使用以下命令获得所有可用的分辨率：

$Query = "SELECT * FROM CIM_VideoControllerResolution"
$res = Get-WMIObject -query $Query | Select Caption

---

您可以从

Win32\u VideoController

WMI类中获取此信息。

VideoModeDescription

属性包括屏幕分辨率和颜色深度

(Get-WmiObject -Class Win32_VideoController).VideoModeDescription;

结果

与其他答案相同，但是对于普通cmd：

---

wmic path Win32\u VideoController get VideoModeDescription

@Shay Levy的上述回答准确地报告了启动powershell会话时处于活动状态的宽度/高度。如果在PS启动后旋转监视器，它将继续报告原始的、现在不正确的值

SystemInformation类提供了另一种获取方向的方法，它在当前PS会话中会发生更改，即使在会话启动后显示器会旋转

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.SystemInformation]::ScreenOrientation
Angle0

[System.Windows.Forms.SystemInformation]::PrimaryMonitorSize
IsEmpty                            Width                           Height
-------                            -----                           ------
False                              1680                             1050

旋转监视器，然后

[System.Windows.Forms.SystemInformation]::ScreenOrientation
Angle90

[System.Windows.Forms.SystemInformation]::PrimaryMonitorSize
IsEmpty                            Width                           Height
-------                            -----                           ------
False                              1050                             1680

以下是基于Shays的答案，它根据OPs的示例格式化每个屏幕的结果

用于格式化以下结果的PowerShell代码：[System.Windows.Forms.Screen]：：AllScreens 横向模式下辅助监视器的输出。1920 x 1200 纵向模式下辅助监视器的输出。1200 x 1920

这似乎只找到了第一个监视器。是否有办法获得所有监视器的分辨率？这里的第二种方法准确报告启动powershell会话时处于活动状态的宽度高度。如果在PS启动后旋转监视器，它将继续报告原始的、现在不正确的值。请参阅下面的答案，了解在同一PS会话中工作的另一种方法，即使在监视器旋转后也是如此。非常好的解决方案，关于更新（WMI解决方案不适用于我，Win 10）。不幸的是，您必须将绑定对象的宽度和高度乘以dpi比例因子（在Windows设置>系统>显示中进行配置），例如。G第一个方法在

ScreenWidth

和

ScreenHeight

中返回空值。第二种方法是完美的
