If you noticed that upon launching TriCaster software that the order and orientation of the screens has changed from what was initially set up in Windows Display Panel, you can fix it by adjusting it in Nvidia Control Panel. To do this, exit to Windows, right click on a blank area in the desktop, and select Nvidia Control Panel
From there, choose Set Up Multiple Displays on the left hand side, and order and adjust the position of your monitors, as needed:
Press Apply on the bottom right when done, and then press Yes when the prompt comes up to keep your changes. Note: If you don't press Yes, it will default to No and your settings will be reverted.
After that, you can close the Windows and go back into TriCaster.
