WMI可能有所帮助.

在Vista +中,有WmiMonitorBasicDisplayParams类,其中"Active"属性告诉您显示是否处于活动状态.

这是一个适合我的例子:

using System.Management;

// ...

var query = "select * from WmiMonitorBasicDisplayParams";
using(var wmiSearcher = new ManagementObjectSearcher("\\root\\wmi", query))
{
    var results = wmiSearcher.Get();
    foreach (ManagementObject wmiObj in results)
    {
        // get the "Active" property and cast to a boolean, which should 
        // tell us if the display is active. I've interpreted this to mean "on"
        var active = (Boolean)wmiObj["Active"];
    }
}
