DisplayFusion

It's one of the best multimonitor application that I've found. Main feature that I use in DF is monitor splitting feature. This works perfectly with my huge 42" 4k monitor. So basicly I split my desktop to four separated virtual desktops. I have tested out many other apps but DF seems to be best for my workflow!

And one of the best thing that it's available from Steam!!!

The triggers is my favorite feature, they rock! I can control window placement for apps exactly as I see fit. You too will love this software if you have multiple monitors!

Uninstallation of DisplayFusion trial left my computer/mouse buggy and required a system restore to fix.

Reliable, great developers (responsive), lots of additonal tools.

I cant live without this software !

I have been using this for years. I love this program! It has so many options that I am sure that I have not explored the half of them. I am REALLY happy about the send to option that allows you to simply click a button on the page title bar and it will send it to the second monitor in multi-monitor systems. No need to exit full screen mode to move a window now. It also gives you the ability to select the power user menu from your cursor position which is quite handy. On top of this, all updates are included when you purchase the program.

I highly suggest getting a rather large wide screen image to stitch across 3 monitors

DisplayFusion lets you set multiple options for how to stitch one wide image into 3
