I have a work laptop connected through a dock and a personal desktop PC, currently using separate monitors, keyboards, and mice for each setup. I'd like to reduce the desk clutter by keeping three monitors on the desk and sharing those monitors, one keyboard, and one mouse between both computers. The laptop would connect through USB-C or its dock, while the desktop uses DisplayPort. Would a KVM switch handle this setup, or would a USB switch combined with manually changing the monitor inputs be a better option?

If you do not need every monitor to switch together, a hybrid setup can be simpler. Keep one monitor permanently connected to the desktop and put the other two on the KVM, or share only the keyboard and mouse with a USB switch while changing monitor inputs manually. This also lets you keep using the home PC on one screen while working on the laptop.
A three-monitor KVM can be expensive and occasionally finicky, especially with high refresh rates. A cheaper alternative is to connect the PC and dock to different inputs on each monitor, then use a USB switch for the keyboard and mouse. You would press the USB switch and change the monitor inputs when moving between computers.
Yes, that is exactly the kind of problem a KVM is designed to solve. It switches the video signals and USB peripherals between the selected computer. Just make sure the KVM supports three monitors, the resolutions and refresh rates you want, and the correct mix of DisplayPort, USB, and USB-C connections.
The laptop may need a USB-C dock or adapter that provides three DisplayPort outputs. A single USB-C-to-DisplayPort adapter will only drive one monitor unless the laptop and adapter support a suitable multi-monitor standard.
Another option is to use a dock or hub for the laptop, connect both systems to a suitable multi-monitor KVM, and plug a powered USB hub containing the keyboard, mouse, camera, and headset into the KVM. A button mounted under the desk or monitor can then switch everything at once. Check the KVM’s maximum resolution, refresh rate, DisplayPort version, and whether it supports all three displays simultaneously.
That approach works well if the monitors already have enough inputs. It avoids putting the video signals through the KVM, which can help preserve higher refresh rates.
