Setting up maximizer

Ok so I set up my 30" monitor (2560x1600) like the following jpeg. Now regions 1,2,3 are all 800x600 in game resolution, but in maximizer they are covering 840,800. Regions 4 and 5 are 1028x768 in game resolution and they cover 1280, 800 in maximizer. I'm trying to figure out what in game resolutions would work better for the top screens as they characters in them look really skinny. Or maybe a better screen setup. I like my current setup better than one large screen surrounded by four very small screens as I can't read their screens very well without using PiP to switch to them (not very good when I'm in a battle.) Any help would be appreciated.
