xrandr -q output is useful for describing the exact configuration. Note in particular the resolution of each monitor, and the offset of each monitor within the overall virtual screen, are shown. E.g. the first one listed for me, LVDS1, is 1366x768, with an offset of 0 horizontal and 1024 vertical (down from the top), so it is configured below the second one listed.
