Running UGA-4KHDMI from USB ports on monitors; will it work?


I want to run 4 Dell U2414H monitors off a laptop in a docking station. Since the docking station does not have 4 available USB 3.0 ports (only 1), I thought of using the USB 3.0 ports on the back of the monitors. Each U2414H has 3 USB 3.0 ports on the back. I envision connecting a Plugable UGA-4KHDMI to a single USB port on the back of each monitor, then the docking station feeding USB to the first monitor, then daisy chaining each successive monitor. The manual of the U2414H says each port will support 4.5W max for each port. (up to 2A on one port.) Will this work?


Hi Dirk,

Thank you for posting the question here!

I am sorry but I didn’t understand your questions well, and I noticed that the Dell U2414H has a built-in 4 port USB hub in it.
I’ll make the correction in the next comment shortly, and please accept my apologies that I initially posted the incorrect answer here.


Unfortunately, our USB graphics adapters don’t support any daisy chaining, and I don’t think the USB port of the Dell monitors support that kind of setup, neither.

If you wanted to connect 4 monitors, I’d recommend you to use a USB 3.0 hub to add more USB ports to your system. Since multiple USB graphics adapters will be connected to the USB hub, please make sure using a self-power USB hub (that comes with it’s own AC adapter), but not a USB bus-powered hub. Plugable also sells that types of USB 3.0 hubs:

Hope this helps! Please feel free to contact us at if you have any further questions.
Thanks again for posting this here!

Hi Dirk,

I am sorry that I misunderstood your question. I’d like to write the correct one here, based on the Dell monitors have the USB hub in it.

Basically you are connecting/nesting (daisy chaining) four USB hubs (it happens to be four monitors as well), and plug a USB graphics adapter into each USB hub.

Please note that, in this configuration, you’d need:

  • connecting four monitors by using a USB cable between.
  • one UGA-4KHDMI graphics adapter per additional monitors (in this case, three).

In theory, that configuration should work, but there are a couple of concerns:

  1. USB 3.0 can be nested up to 5 depth. In your scenario, the 4th monitor/hub will probably hit the last depth and should be fine. It depends on the design of the docking station and the hub in the monitor, so please keep it in mind.

  2. You may hit the limitation of USB 3.0 controller resources .This depends on how many USB devices you are connecting to your single PC: there is a total number of “endpoints” limit of USB 3.0 devices. It’s very hard to predict, but since you are nesting the dock and the 4 USB hubs, it’s possible you’d see the error message when you tried to connect 3rd or 4th monitors.

Please read the related blog post here:…

The conclusion is, we think it’s probably working fine, but cannot guarantee it 100% for sure.
