From Actual Tools:
Actual Multiple Monitors is the set of productivity tools aimed to enhance the usability of Windows user interface when working with multi-monitor configurations. The smart application emulates standard Windows services on secondary monitors and offers new window management services to free you from routine clicking and let you concentrate on your work undisturbed. Features include multi-monitor taskbar and task switcher, background wallpaper, screen saver, desktop management tools and desktop mirroring tools, and advanced multi-monitor window management.
What's new in this version:
Actual Slideshow Screensaver now can skip the content of sub-folders
when adding a folder to slideshow playlist.
After downloading the update, setup did not run after clicking on the
tray balloon "Click here to install it right now" message if the
"Load at startup" option was enabled.
Windows 8.1: ActualMultipleMonitorsShellCenter.exe sometimes crashed when
trying to display a preview thumbnail.
Makes setting up multiple monitors a breeze
Adds new functions, like dividing a large monitor into several virtual monitors
Expensive - but check out the deal lurking in there.
I've been addicted to multiple monitors since 2011 and cannot understand how I got along without them before. I now use a laptop and two external monitors on which most of my real work is done. I was using a free download to manage these two external monitors, but that tool was not fully compatible with Win 10. I tried Actual Multiple Monitors on a 30 day trial and love it... it simplifies the process of extending your display out to more than one monitor and works well. I also tried out the 'Desktop Divider' feature that lets you carve one monitor into multiple virtual monitors, just about anyway you want to and it works great.
Actual Multiple Monitors is not cheap - it's about $30, but is worth all that. But wait - there's more. You can purchase - for the same price - a complete suite of handy tools in a package called Actual Window Manager - including Actual Multiple Monitors. This adds a number of cool programs. Some are more valuable to me than others... one lets you automatically roll a non-active window up to just the title bar when you move to another application. One places a small tool at the top of file manager windows which lets you quickly - one click - move to a favorite folder on your system. Another lets you set up multiple desktops so that you can easily move from "All Work" to "All Fun" whenever you want.
I've only just started diving into all the added features of Actual Window Manager, but love what I have tried so far.
Makes easier to work in a multi-monitor environment.
Compatible with Windows 8 or 8.1
It is updated frequently. Last version is 8.2.
It is packed with functions, I use every day the hotkeys to move the mouse quickly between monitors. I configured the task bar to show the same on every window (including start menu). By default the mouse movement stops a little while when you reach the edge of the monitor to prevent it to go to the next monitor too easily.
It is possible to disable load at startup through the configuration window (accessible through a different icon). This way you can load the application only if you need it. For example when you connect the laptop to the monitors in the office. You can stop or unload Multiple Monitors when you leave without shutting down the laptop avoiding to consume system resources.
The configuration window has so many functions and customizing capabilities for all people needs that it is difficult to find at the beginning what you need. I would like some sort of simplified menu or wizard with the most common functions organized in categories and everything else grouped in these categories.
Issues I found with the "Modern" Windows 8 UI: When using the task switcher (alt + tab) the mail window from modern UI stills gets duplicated. When moving the mouse to the main screen using the hot key combination, it stills change to desktop when viewing an application in the Modern UI mode (for example the new IE)
This software is worth to have if you work with multiple monitors, especially if it is three or more where it is very cumbersome to move between the entire work space with the limited tools provided by Windows.
