Is it possible to run slave windows at the same in game resolution as the main window?

I'm running two monitors one set to 1-1 (1920x1200) and another that runs the slaves in a 2x2 config at something like 840x525 each. When I swap the windows out the swap goes almost instantly and I don't swap leader a lot so the speeds not really an issue but I was wondering if its possible to run the slave windows at a 1920x1200in game resolution as well. I set the maximizer option to 1920x1200 and also set it inside of wow as well either way the slave wows always change the resolution down to a resolution thats much closer to the 840x525..
