Question

如何将Windows Display设置的刷新率从59更改为60？

我找不到有关如何通过PowerShell或批处理脚本完成此操作的任何信息。我只会在屏幕分辨率上找到任何东西。

我想要完成的是：

If 60 hz then set 59 hz
        else (set 60 hz)

但是它似乎没有任何本地cmdlet吗？

我只尝试搜索任何cmdlet或其他wmi解决方案，可能可以做到这一点，但只发现了如何更改显示分辨率。

编辑：

与mhu发布的内容和wmi结合在一起，我设法获得了某种接近正常运行的解决方案。

$RefreshRate = Get-WmiObject -Class:Win32_videocontroller | Select-Object -ExpandProperty currentrefreshrate

if ($RefreshRate = 60){
    Set-ScreenResolution -Width 2560 -Height 1440 -Frequency 59
    }
else {
    Set-ScreenResolution -Width 2560 -Height 1440 -Frequency 60
    }

但是，这仍然不能使它在两个刷新率之间交换。关于如何仅从WmiObject获取数字的任何想法吗？

EDIT2：因此，我向选择对象添加了-ExpandProperty参数。现在它只输出60或59。但是它仍然不会在两个：（。

    Add-Type $pinvokeCode -ErrorAction SilentlyContinue

    [Display.PrimaryScreen]::ChangeRefreshRate($frequency) 
}

function Get-ScreenRefreshRate
{
    $frequency = Get-WmiObject -Class "Win32_VideoController" | Select-Object -ExpandProperty "CurrentRefreshRate"

    return $frequency
}

要在您的情况下调用此功能：

$currentFrequency = Get-ScreenRefreshRate
$newFrequency     = if ($currentFrequency -eq 59) { 60 } else { 59 }

Set-ScreenRefreshRate -Frequency $newFrequency

更改Windows 10屏幕刷新率。 59如果60，则59如果60
