Check Monitor Brightness

If you want to check your current display brightness (preferably on notebooks, of course), here's a quick function:

function Get-MonitorBrightness
{
    param($ComputerName, $Credential)

    Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightness @PSBoundParameters | 
        Select-Object -Property PSComputerName, CurrentBrightness, Levels
} 

It even supports -ComputerName and -Credential, so you can query remote systems as well.

And if you submit a comma-separated list of computer names or IP addresses to -ComputerName, you get the results for all of those–provided you have local Admin privileges on these systems.
