Hello I just bought the TBT3-UDZ and it works fantastic on my personal Mac Air 2019 w/thunderbolt 3, however, I wanted to use this docking station for my work laptop as well, which does not have a thunderbolt 3, but it does have a USB-C. My work laptop is Dell Latitude and I run two monitors plus the laptop screen for a total of three screens. I am running displayport cable. The dock does not seem very responsive to the Dell, as I have a few USB 3 devices plugged in (e.g. a wireless mouse and keyboard), but the dock is not recognizing them right away and I cannot use. Also my Monitors seem to only function at 1940x1080 at 30 hertz. Do I need to buy a USB-C cable and run it from the from front of the docking station to the laptop?
Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.
Can you please let me know what specific model Latitude you’re using? I’ll need to double check the specifications to see why this behavior may be occurring. Depending on your system specifications, it may limit your displays to 30Hz due to graphics card capabilities. I expect if you used a single display it would offer you up to 60Hz.
In addition, please note that a USB-C cable will not change the behavior. Thunderbolt 3 cables like that which shipped with the dock are backwards compatible with USB-C, so it won’t be causing this behavior you’re seeing.
Finally, can you clarify the resolution? Did you actually mean 1940x1080 or is it 1920x1080 (standard 1080p)? I have never seen 1940x1080 before which is why I ask.
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
