How to get screen resolution from machine that has no screen?

Question

I am trying to get the screen resolution of a headless machine that is running selenium tests.

Have already tried using System.Windows.Forms.Screen.PrimaryScreen as well as other options in Forms . I have tried using powershell and c#. Usually they tell me either the screen size after I RDP into the machine (which is just the size of the remote session) or the requests fail (if I try to get the size from a PSSession).

Thanks in advance!

Answer 1

You're on the right track, the screen class gives you the info you want:

$Screen = [system.windows.forms.screen]::AllScreens
"$($Screen.Bounds.Width) $($Screen.Bounds.Height)"

Answer 2

The answer to my issue turned out to be a hardware one and not a software one. I talked to my IT dept and they told me that they could change the resolution of VMs from their console for Nutanix. I had no idea that this was the issue.

Make sure to talk to your IT or VM admin if this is the case. This is the answer!
