DisplayFusion is a multi-monitor management suite. It adds a taskbar—complete with Aero peek—to every monitor, supports spanned or monitor-dependent wallpaper with position fine-tuning.
You can make all of your displays mirror each other, or extend your workspace with different apps and windows on each display. If you use an external display with your Mac notebook, you can also use closed-display mode.
