Help! Dell XPS 13 (2020) Not Recognizing External Monitor Through Plugable UD-ULTCDL Docking Station

[kevinsky89]

Hi there

I recently snagged a Plugable UD-ULTCDL docking station to finally organize my desk setup. I’m using it with my trusty Dell XPS 13 (2020) running on Windows 11. Everything’s working swimmingly – the dock keeps my laptop charged and all my peripherals, like my keyboard and mouse, connected seamlessly. However, I’m having a bit of a snag getting it to recognize my external monitor.

Here’s the breakdown:

Docking Station: Plugable UD-ULTCDL
Laptop: Dell XPS 13 (2020) - Windows 11
Monitor: Dell UltraSharp U2719D
Connection: HDMI cable from docking station to monitor

Now, the weird part: the monitor stubbornly stays in sleep mode, like it’s not receiving a signal at all, when connected through the docking station. I’ve tried switching HDMI cables and ports on both the dock and monitor, but no luck. Interestingly, the same monitor works perfectly when I connect it directly to my laptop using a USB-C to HDMI adapter.

To try and fix things, I’ve already:

Updated the docking station’s firmware and drivers from the Plugable website.
Made sure all the drivers on my laptop are up to date.
Hooked up a different monitor to the docking station (same issue!).
Restarted both my laptop and the docking station several times.

I also check this: https://support.plugable.com/t/plugable-usb-c-mini-docking-station-causing-interference-with-my-krk-monitors-can-anyone-help-pleasegenai But I have not found any solution. So, here is why I am reaching out: has anyone else encountered this before? Maybe there’s a specific setting or configuration I’m missing? Any advice you can offer would be a lifesaver – my external monitor is essential for my work.

Thanks a ton in advance for your help!

Best regards
