I found a great tool the other week that should work. You set your display(s) up the way you want, and then save a profile. To get back to that setting, you can just run the utility through a commandline with that profile as a parameter. Make a batch file to do that, and then set a shortcut to the batch file if needed. It's a little more effort to do this the first time, but after that it just runs when you double-click the icon.
I can't for the life of me remember the name of it, but I think it was this one -

I tried nirsoft, displaychanger and a few others, but nothing else would work in an AHK script from AM to load a resolution, then load an emulator, then switch back to the AM-ideal resolution when the emulator closed.
