更改Windows 10屏幕刷新率。如果是60，则是59；如果是59，则是60
更改Windows 10屏幕刷新率。如果是60，则是59；如果是59，则是60
提问于 2019-06-03 17:47:50
如何将Windows显示设置的刷新率从59更改为60？
我找不到任何关于如何通过PowerShell或批处理脚本来完成此任务的内容。我只会在屏幕分辨率上找到任何东西。
我想要实现的是：
If 60 hz then set 59 hz
else (set 60 hz)但它似乎没有任何本机cmdlet？
我只尝试搜索任何可能做到这一点的cmdlet或其他wmi解决方案，但只找到了如何更改显示分辨率。
编辑：
结合mhu发布的内容和wmi，我已经设法获得了一个有点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
}然而，这仍然不能使其在两个刷新率之间进行交换。关于如何从WmiObject获取数字，有什么想法吗？
EDIT2:所以我在Select-Object中添加了-ExpandProperty参数。它现在只输出60或59。但它仍然不能在这两者之间进行交换:(.
