Screen resoulution problem

Hi

I took a picture to show you how my screen is currently.

I want the Window on my right screen, to be streched all the way to the right side of the screen. But I can't figure out how. This is how my .bat file looks like.

p.s I'm using WoW maximizer.

REM Left monitor
c:\wow2\maximizer.exe --margin 0,0,0,0
REM Right monitor
c:\wow3\maximizer.exe --margin 480,30,1920,0

thanks for any help, and yeh, my resolutions on my screens are:

left screen: 1920 x 1080
right screen: 1680 x 1050
