Setup. MBP 15"
Dell 26" external monitor over DVI

I may just be loosing my mind here, but I can't seem to figure out a way to have my MBP be the default (i.e. - menu bar, dock, etc) monitor in a setup and have the external monitor be secondary.

basically -- i want to be able to have the external monitor be for 'glanceable' information such as stock charts, etc.

any help is greatly appreciated + thanks in advance.
