DisplayFusion will make your dual monitor (or triple monitor or more) experience smooth and painless. Advanced multi-monitor wallpaper support, Flickr integration for image searching and fully customizable window management hotkeys are just a sample of the many things DisplayFusion can do. DisplayFusion is also available in many different languages.
Whats new in Beta 9?
Change: Added a “Use the same Image on each Monitor” wallpaper option
Change: “Image Scaling” for the wallpaper is now a per-monitor setting, even when spanned (allows for better flexibility with different resolution monitors)
Fix: No longer crashes when clicking the “Identify” button in the Monitor Configuration window
