How can I make the “Show desktop” function in Windows 7 only hide the windows on a specific monitor?

Question

I have three monitors and have a problem with the "Show desktop" function in Windows.

Whenever I hit the icon, all windows will be hidden but I only want to hide all the windows on monitor X.

Is this possible?

You can do this using UltraMon. It costs $39.99, but it has a few other really useful features, like Taskbars on the non-primary monitors.

Right-click System Tray icon > Window Management > This Monitor > Show the Desktop

Or, you can make a keyboard hotkey to Show Desktop on only the monitor where the mouse is.
