Mouse lock multimonitor setup

[Carlmiester]

In the process of building a new triple monitor gaming/media rig and I am obsessed with hardware monitoring.

 

I want to get a smaller (like 5-7in) hdmi power display as a fourth monitor, and have all my monitoring software open on that screen on startup.

 

My problem is, I have done something similar before a long time ago, and I absolutely hated when I would flick the mouse across the screens and it would land on the tiny screen. Every where I search, mouselocks are for keeping the mouse on a single screen.

 

Is there any built in, or third party software for Windows 10 that I can toggle to stop the mouse from going onto just that one screen, without blocking it's movement to other screens?

 

First post here. I'm not much of a forum guy, so I didn't know whether to post this in the monitor or mouse section.
