My screen resolution is 1280x1024 running Win 8 RP

I formatted my computer and reinstalled Win 8 CP because I had too many BSODs. When I installed Win 8 CP and created a local account. I had 5(or 6) tiles per column. But once I switched to the Microsoft account to get my synced wallpaper and lock-screen, the Start screen resolution changed and I got a max 3 tiles per column. The size of all metro apps including the Settings app changed and became awkwardly bigger.

Is there a way to get back 5 tiles per column? Essentially changing the resolution of the start screen?
