P45 Quad Screen Layout

I would like to know how can I configure the layout for the quad monitor set up for the following monitor layout

               Mon 4

Mon 1 - Mon 2 - Mon 3

Now it is lined up as next to Mon 3 and I cant go from Monitor 2 up to Monitor 4.

Is there anyway that this can be done or is this a limitation of the firmware/

Thanks in advance
