Resolutions 24inch monitor with 1920x1200 and 22inch with 1680x1050

I edited the wow config file to say gxResolution "840x525" for the alts on secondary pc.

Here is my batch file

REM batch file to launch 5 evenly spaced wows
REM Left monitor
c:\wow1\maximizer.exe --margin 0,0,0,0
REM top of right mon
c:\wow2\maximizer.exe --margin 0,675,1920,0
REM bottom of right mon
c:\wow3\maximizer.exe --margin 525,150,1920,0
REM bottom right, right screen
c:\wow3\maximizer.exe --margin 525,150,2760,840
REM Top right, right screen
c:\wow3\maximizer.exe --margin 0,675,2760,840

And this is how it comes out, the right hand monitor is a bit wrong, any ideas? thanks
