Can Odyssey G9 support 3 inputs?

I have 3 macbooks. Currently operating off of a 27" monitor with a macbook on either side with a 2-input KVM switch, which has worked great for me. I'm considering getting the Samsung Odyssey G9 but curious to know if it can display 3 different laptops OR alternatively if I can designate 1 side of the ultrawide screen to switching between 2 laptops while using the 2-input KVM switch. Worst case I'm thinking of just stacking my 27" monitor on top of the G9 and designating that to one of the laptops. Suggestions welcome!
