Since I started streaming in March, I have been using a 2 PC setup using NDI Tools for OBS Studio, making my laptop the encoding computer and keeping the desktop for gaming. This tool is amazing as it allows you to use a laptop you might not use (since I bought a desktop) to partake in the tasks of encoding, however, you still need to go back and forth with both computers to make it work.
Fortunately (and unfortunately, this is more an inside thing of mine cause I believe the excess of convenience does more harm than good) convenience exists and you can use a program to control multiple computers on a network.
Program's called Input Director and it is incredibly simple to set up and best of all... 'tis free!

I essentially found this program out of the need to control OBS on my laptop, allowing me to put Sources directly on the laptop, giving the desktop more freedom for other tasks.
With this software, you can control as many (as far as i'm concerned, there's no limit that i've seen) computers as you want on a network using a single mouse+keyboard. It also has security, meaning you'll need to confirm and accept a computer can be managed through the software, prior to using it. So I made my laptop possible to manipulate via my desktop but not the other way around.
Plus, a thing I think is amazing, is that you can literally still bring your mouse over to, in my case the laptop, and manipulate it even with a game in fullscreen.
Here's some more images of examples and stuff...
Hopefully this helps someone out as it helped me.
Often I tend to think the things I find out about are super straight forward that 'everyone' must already know about them but more often than not I find out that there's a lot of things people can find out about so here it is.
If I find more stuff that is helpful like this I will post about it as well.
Thank you for reading and have a great day.
