    Get-DisplayResolution is correctly displaying the screen resolution to the console. I would like to validate that within a script.

    The value is coming back as 1 2 8 0 x 8 0 0 (spaces or some special char in between the numbers)

    How can I validate the value in this System.Object[] to return True or False based on the resolution being correct?

    I'm wondering if you are seeing Unicode output or something. I don't get that on my computer.

    If you run "Get-DisplayResolution | GM" what's the first line of output?

    That's a nasty one, looks like the Get-DisplayResolution outputs ASCII NUL, can be fixed by replacing those characters:

    ((Get-DisplayResolution)[0] -replace $([char]0)) -eq '1280x800'

    This outputs a boolean True if the resolution equals 1280×800 (forum software messes up the code, sorry), note.. on my test environment the Get-DisplayResolution outputted an array, so that's why I've selected the first item in the array.

    That works. Thanks Daniël!

    ((Get-DisplayResolution)[0] -replace $([char]0)) -eq '1280`x800'
