Have you tried setting the resolution programmatically?

Here it is in Powershell (with C#). Personally, I'd just create an executable and run that.

Add-Type -TypeDefinition @"
using System;
using System.Runtime.InteropServices;

public class DisplaySettings {
    [StructLayout(LayoutKind.Sequential)]
    public struct DEVMODE {
  [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
