The primary monitor is index 0, secondary monitor is 1, and so on. Valid values range from 0 to 32. .EXAMPLE Get-DesktopScalingFactor -Monitor 0 Returns the scaling factor percentage for the primary monitor .EXAMPLE Get-DesktopScalingFactor 1 Returns the scaling factor percentage for the second monitor using positional parameter #> function Get-DesktopScalingFactor { [CmdletBinding()] param( ######################################################################## [Parameter( Position = 0, Mandatory = $false, HelpMessage = "The monitor index to check (0 = primary monitor)" )] [ValidateRange(0, 99)] [int] $Monitor = 0 ######################################################################## ) begin { # log the requested monitor index for troubleshooting Write-Verbose "Getting scaling factor for monitor index: $Monitor" } process { # invoke the native method to retrieve the current scaling factor # uses the GenXdev.Helpers.DesktopInfo class's static method [GenXdev.Helpers.DesktopInfo]::getScalingFactor($Monitor) } end { } } ################################################################################ |
