Doesn't work if invoked in non-interactive mode

[Dvvarf]

Hello,

First of all, thanks a lot for the module!

I'm having an issue trying to run it in non-interactive mode (as SYSTEM user) though. I get the following error:

Failed to get the number of physical monitors attached to 'WinDisc'.
    + CategoryInfo          : NotSpecified: (WinDisc:LogicalDisplay) [Get-Monitor], ApiException
    + FullyQualifiedErrorId : GetPhysicalMonitors,MartinGC94.MonitorConfig.Commands.GetMonitorCommand
    + PSComputerName        : localhost

I'm trying to use this module in a scheduled task and can reproduce this error by using Invoke-CommandAs module:

Invoke-CommandAs -ScriptBlock { Get-Monitor } -AsSystem

I've also tried fetching specific monitor, but to no avail -- in this case there is no error, but no return as well:

Invoke-CommandAs -ScriptBlock { Get-Monitor -DeviceName "\\.\DISPLAY1" } -AsSystem

I understand that there is a high chance it's not possible to get monitor information in non-interactive mode, since there is no window/display handle available. However, perhaps there is some way?

Thanks in advance!

I think it's just an inherent limitation of the API. Maybe you can use psexec with the -i switch to launch PowerShell in an interactive session?

I see... Thanks for confirming that it's probably not possible. I'll try to invoke it in an interactive context somehow and I'll take a look at the psexec -i, thanks.
