Programmatically change screen resolution?

Question

Is there a way to programmatically change the screen resolution or enable/disable multiple monitors in Windows XP? For example to change from 1024x768 with one monitor to 1

Answer 1

You can easily script this with http://www.autohotkey.com

Here's a script for swapping between one monitor and two monitors with Windows+1 and Windows+2

#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
#Warn  ; Recommended for catching common errors.
SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir%  ; Ensures a consistent starting directory.
