Is there a way to set the zoom for the internal display? I know if I were to use powershell to input:
$Host.PrivateData.Zoom = 150
it would zoom just the powershell window to 150%. I need "everything" to be 200%.
Zoom is something that is part of Windows apps.
Screen resolution is what it sounds like you are after, meaning to expand everything on that screen.
See these discussions and sample code.
Sets the resolution of the main monitor- Requires PowerShell V2
How to do a Powershell (or other) script to change screen resolution?
