The kvm switch is then connected to my 2 external monitors.
When i plug The hdmi cables in individually to the pluggable unit each of the displays will work so i get an extra display. When both are plugged in get no display on one of the 2 screens, only one screen is detected by my Surface Book 2. My Surface book 2 is running Windows 11.
Also to note the KVM switch is working fine as my PC routes through it and the 2 external monitors work fine.
Travis reached out to us directly as Omar had previously requested, and we have sent our direct reply.
We wanted to provide an update to this thread with the relevant information from our direct reply for the benefit of others:
"The level of functionality provided by the Plugable TBT4-HUB3C Thunderbolt 4 hub is ultimately determined by the capability of the host PC to which it is connected. On its own, the hub does not add any additional capabilities to the host PC.
The Microsoft Surface Book 2 laptop you are using has a single USB Type-C port that allows for the connection of a maximum of one external display. It is not possible to drive two external displays via the Surface Book 2’s USB Type-C port.
This is an internal limitation of the laptop, and this internal limitation is why both displays are not working when connected to the TBT4-HUB3C. To be clear, this is an internal limitation of the laptop, not a limitation of the TBT4-HUB3C.
Given the laptop’s internal display limitation, it will not be possible to connect two displays to the laptop via the TBT4-HUB3C.
We offer a 30-day no-hassle return policy for all products sold by Plugable and fulfilled by Amazon. If your purchase meets those requirements, I am afraid I would have to recommend that you return the product to Amazon for a refund. "
