I have 3 monitors set up on my rig and have been using the paid version of Display Fusion since 2010.
What I like best about it is the ability to have different images on all 3 monitors and the ability to change them at a setting of my choice. I have one set up to change every 55 minutes, one at 60 minutes and one at 65 minutes. I have over 1,000 images Display Fusion can randomly choose from.
The Title Bar buttons are also nice, with the option to choose which ones you want to use. I only use 2 right now. One to move a window to the next monitor and one to center the window in the monitor and scale it to fit the screen.
There's a plethora of other options available as well. Most of which I haven't even investigated yet.
If you have more than one monitor and the ideas above sound good to you, I recommend Display Fusion.
