34" S65TC UWQHD Thunderbolt 4 ViewFinity Monitor

[debhyp]

Recently brought this monitor and I have 2 laptops connected to it. One using the thunderbolt cable and the other using the HDMI. I am using the 2 usb ports on the monitor for my mouse and keyboard. 

I can display both laptops (PIB) on the screen but can't get the mouse/keyboard to auto move between the screens.

I presumed the monitor would do this automatically with the built in KVM switch.

Am I missing something? Is there a setting I need to switch on?

Thanks
