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

Question

我正在使用以下脚本通过 WMI 获取 Windows 中的屏幕分辨率。该脚本在计算机处于横向模式时工作正常，但在纵向模式时返回错误值。 XP 下可以正常使用，Vista 下没试过。谁能确认这是 Windows 7 WMI 中的错误。

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

Answer 1

根据记录，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：

在多显示器环境中，您可以通过以下方式获取所有显示器的信息：

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}

Answer 2

您可以从 Win32_VideoController WMI 类中获取它。 VideoModeDescription 属性包括屏幕分辨率和颜色深度。

(Get-WmiObject -Class Win32_VideoController).VideoModeDescription;

结果

1600 x 900 x 4294967296 colors

Answer 3

与其他答案相同，但对于普通 cmd：

wmic path Win32_VideoController get VideoModeDescription

Answer 4

这是基于 Shays 的答案，仅根据 OP 的示例格式化每个屏幕的结果。

用于格式化结果的 PowerShell 代码： [System.Windows.Forms.Screen]::AllScreens

Add-Type -AssemblyName System.Windows.Forms
$screen_cnt  = [System.Windows.Forms.Screen]::AllScreens.Count
$col_screens = [system.windows.forms.screen]::AllScreens

$info_screens = ($col_screens | ForEach-Object {
if ("$($_.Primary)" -eq "True") {$monitor_type = "Primary Monitor    "} else {$monitor_type = "Secondary Monitor  "}
if ("$($_.Bounds.Width)" -gt "$($_.Bounds.Height)") {$monitor_orientation = "Landscape"} else {$monitor_orientation = "Portrait"}
$monitor_type + "(Bounds)                          " + "$($_.Bounds)"
$monitor_type + "(Primary)                         " + "$($_.Primary)"
$monitor_type + "(Device Name)                     " + "$($_.DeviceName)"
$monitor_type + "(Bounds Width x Bounds Height)    " + "$($_.Bounds.Width) x $($_.Bounds.Height) ($monitor_orientation)"
$monitor_type + "(Bits Per Pixel)                  " + "$($_.BitsPerPixel)"
$monitor_type + "(Working Area)                    " + "$($_.WorkingArea)"
}
)

Write-Host "TOTAL SCREEN COUNT: $screen_cnt"
$info_screens

横向模式下辅助显示器的输出。 1920 x 1200

# TOTAL SCREEN COUNT: 2
# Primary Monitor    (Bounds)                          {X=0,Y=0,Width=2560,Height=1600}
# Primary Monitor    (Primary)                         True
# Primary Monitor    (Device Name)                     \\.\DISPLAY1
# Primary Monitor    (Bounds Width x Bounds Height)    2560 x 1600 (Landscape)
# Primary Monitor    (Bits Per Pixel)                  32
# Primary Monitor    (Working Area)                    {X=0,Y=0,Width=2560,Height=1560}
# Secondary Monitor  (Bounds)                          {X=2560,Y=0,Width=1920,Height=1200}
# Secondary Monitor  (Primary)                         False
# Secondary Monitor  (Device Name)                     \\.\DISPLAY2
# Secondary Monitor  (Bounds Width x Bounds Height)    1920 x 1200 (Landscape)
# Secondary Monitor  (Bits Per Pixel)                  32
# Secondary Monitor  (Working Area)                    {X=2560,Y=0,Width=1920,Height=1160}

纵向模式下辅助显示器的 输出。 1200×1920

# TOTAL SCREEN COUNT: 2
# Primary Monitor    (Bounds)                          {X=0,Y=0,Width=2560,Height=1600}
# Primary Monitor    (Primary)                         True
# Primary Monitor    (Device Name)                     \\.\DISPLAY1
# Primary Monitor    (Bounds Width x Bounds Height)    2560 x 1600 (Landscape)
# Primary Monitor    (Bits Per Pixel)                  32
# Primary Monitor    (Working Area)                    {X=0,Y=0,Width=2560,Height=1560}
# Secondary Monitor  (Bounds)                          {X=2560,Y=0,Width=1200,Height=1920}
# Secondary Monitor  (Primary)                         False
# Secondary Monitor  (Device Name)                     \\.\DISPLAY2
# Secondary Monitor  (Bounds Width x Bounds Height)    1200 x 1920 (Portrait)
# Secondary Monitor  (Bits Per Pixel)                  32
# Secondary Monitor  (Working Area)                    {X=2560,Y=0,Width=1200,Height=1880}

Answer 5

@Shay Levy 的上述答案准确地报告了 powershell 会话启动时处于活动状态的宽度/高度。如果您在 PS 启动后旋转显示器，它会继续报告原来的、现在不正确的值。

SystemInformation 类提供了另一种获取方向的方法，即使在会话启动后显示旋转，它也会在当前 PS 会话中发生变化。

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

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

旋转显示器，然后...

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

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

Answer 6

您可以使用以下命令获取所有可用的分辨率：

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

Answer 7

简而言之，这将分别为您提供第一个屏幕（如果有很多）的宽度和高度

$height = (((Get-WmiObject -Class Win32_VideoController).VideoModeDescription  -split '\n')[0]  -split ' ')[2]
$width = (((Get-WmiObject -Class Win32_VideoController).VideoModeDescription  -split '\n')[0]  -split ' ')[0]
