async_off: Turn off the monitor. Use this value if NirCmd remains in memory when using monitor off. low: Set the monitor to low power state. This command only works in systems that support this feature.

I've been using nircmd to turn off the monitor/display of various PCs like so: The cmdwait 1000 part just adds a 1 second delay (to let the last keystroke and mouse movement end) before turning off the display. This has worked for 10+ years.

現在您已經安裝了 NirCmd，您可以使用它來關閉螢幕並完成其他任務。 不可否認，每次想要關閉螢幕時打開命令列並輸入命令可能是最不方便的解決方案。
