Most Diablo III players prefer the "Fullscreen" display mode because it provides the fastest video output and the smoothest game experience. However, as the game does not support multiple monitors, those users who have more than one monitor quickly discover that fullscreen Diablo III occupies the primary display only. The secondary monitor (or monitors) stays free for some parallel activity (like web surfing, chatting, or even working).
However, the game locks the mouse cursor within the primary monitor boundaries and minimizes its window if the user presses the Alt+Tab hotkey, thus preventing any kind of easy parallel operation. Indeed, the task switching process consumes time, since the game needs to free resources when it is minimized and then to allocate them again when the user switches back.
Actual Multiple Monitors, an Actual Tools product extending typical Windows multi-monitor functionality, proposes a better solution. The program simply turns off mouse lock as soon as the user presses a pre-defined hotkey (Ctrl-Alt-Shift-I by default) allowing easy switching to other applications and tasks running on other monitors of the system. This trick results in smooth transition from playing to another activity and back.

Of course, this option works with other games too, not only Diablo III. And the range of other options that Actual Multiple Monitors has makes this feature-rich application a "must have" tool for any multi-monitor system user.
