Just check out whether you can stretch your display into 2 monitors. Depending upon the Graphics card you have, you will have to invoke the corresponding graphics driver interface. Normally you could get in using rt click on free area of your desktop, your graphic card properties, options, modes etc., may be listed there.
If you can stretch, then you should be able to have ODIN Diet stretched to both the monitors, in which case you can move and resize the inner windows of ODIN Diet to your liking. I am not using 2 monitors, but I have checked them up earlier, not ODIN though!
