I'm trying get the current screen resolution on windows via command line.
Based on most of the answers I've found, I should use:
wmic desktopmonitor get screenheight, screenweight
But this returns the max supported resolution of the display device, not the current one, which is what I need.
Example:
I'm using a 4k monitor, but currently set to display only at 1920x1080. When I run the command above, I get:
ScreenHeight ScreenWidth
2160 3840
How do I get the current screen resolution on windows via command line?

Dealing with high DPI made this somewhat challenging because most Windows API functions return a scaled version of the resolution for compatibility unless the application declares high DPI awareness. Inspired by this Stack Overflow answer I wrote this PowerShell script:
Add-Type @"
using System;
using System.Runtime.InteropServices;
public class PInvoke {
[DllImport("user32.dll")] public static extern IntPtr GetDC(IntPtr hwnd);
[DllImport("gdi32.dll")] public static extern int GetDeviceCaps(IntPtr hdc, int nIndex);
}
"@
$hdc = [PInvoke]::GetDC([IntPtr]::Zero)
[PInvoke]::GetDeviceCaps($hdc, 118) # width
[PInvoke]::GetDeviceCaps($hdc, 117) # height
It outputs two lines: first the horizontal resolution, then the vertical resolution.
To run it, save it to a file (e.g. screenres.ps1) and launch it with PowerShell:
powershell -ExecutionPolicy Bypass .\screenres.ps1
I had a similar problem.
Try this:
wmic PATH Win32_VideoController GET CurrentVerticalResolution,CurrentHorizontalResolution
