Connecting PC and Laptop to Dock/Peripherals

There are a number of ways to do what you want, but you haven't provided enough information.

You can use a KVM switch to toggle between the notebook and desktop.  Whether you can share the dock with the desktop depends on what ports it has.  Most desktops, even with USB-C do not support video output over USB-C, while notebooks do.  

Hi Enjn63, 

Motherboard in desktop doesn't have USB-C. It has 4 x USB 3.1 Gen 1 ports and 2 x USB 3.1 Gen 2 Ports.  

It's still difficult to assess what you need. 

The notebook comes into play:  does it have Thunderbolt, or at least a USB-C connection that supports displayport ALT mode (i.e., video output)?  If it doesn't, that changes the requirements.  If it does, the monitor should work through the docking station.

There are ways to add USB-C to a desktop system, but those require an open PCIe slot, and not all USB-C cards will do the job -- you need one that can do displayport ALT mode output.

If the goal is simple monitor sharing, a KVM switch will also do the job.  These range from sub-$100 basic models to more advanced ones that are both more expensive and more capable in terms of video output.

And if both systems are networked to the same router/access point, remote desktop is another option - it will let you log into one system from the other. Note that all windows systems can be connected to by RD, but only Windows Pro can initiate the connection, so at least one of your two systems must be running Windows 10 or 11 Pro.

If those are all external USB devices you want to share, all you need is a USB hub with a built in A-B switch.

There are hundreds of choices in these with varying numbers and types of USB ports on them.

The one thing you won't be able to do is share an internal laptop webcam with another system this way.

My current setup has everything connected to the Dell WD19TBS dock, including the monitor via Displayport. The laptop is then connected to the dock via a thunderbolt port. 

The desktop unfortunately doesn't have an open PCIe slot. 

Remote desktop isn't an option since this is a work laptop

My end-goal is to be able to have both desktop and laptop use the same keyboard, mouse, webcam, printer, etc. 

In that scenario, would the dock no longer be necessary then?
