I have three monitors which I regularly use in two configurations:

• Duplicated Screen on A and B
• Extended Screen on B and C

Because I often switch between those two configurations, the manual setup via the Win 7 Screen Resolution dialog is costing me time.

I need a simple tool with the following features:

• Allows to save Multi-Monitor configurations for later reuse
• Allows to quickly switch between those pre-saved configurations
• Preferably: Allows to do the switching through hotkeys
• Works on Windows 7
• Free or very low one-time price (<10$/€)

DisplayFusion and UltraMon are good tools, but come with a plethora of features I don't need for a larger price than what I am looking for. I was hoping to find a free or cheap alternative that only does this one task (monitor switching) for me.
