Amazon description for "Plugable Thunderbolt 3 Dual DisplayPort" confirmed?

Hi, I plan to buy a Dell XPS Laptop which is known to have only a 2-Lane Thunderbolt 3. In your Amazon description for the Plugable “Thunderbolt 3 Dual DisplayPort” it states that it supports “two DisplayPort monitors up to 4096x2160@60Hz (4K)” for the “Dell XPS 9350 & 9550” amongst others. Can you please confirm that! Because normally that shouldn’t be possible since a 2-Lane Thunderbolt has only 20GBits in one direction as far as I know. Beyond that Dell support empathically told me that two DisplayPort monitors with up to 4096x2160@60Hz (4K) would only be supported by their “TB16 Dock”.

Thank you!

OK, thogh I really took some time to research if your produt would work I maybe should have just a scrolled wdown a little bit in the Amazon description where I now found the exact answer to my question. :slight_smile:
However, I will first believe when I see it with my own eyes :wink:

Hi Francisco,

Direct reply from March 14th:

"Hi Francisco,

Thanks for contacting us and I would be happy to answer your question.

Our Plugable Thunderbolt 3 Dual Display DisplayPort adapter ( is capable of driving two DisplayPort-enabled displays both at 4K resolution at the same time. This has been confirmed with the 9350 and 9550 model in our test lab.

One important note is that we have found that Dell XPS systems need to have all the latest relevant updates from Dell (system BIOS, Thunderbolt 3 driver, Thunderbolt 3 NVM firmware, and internal graphics driver) installed in order for things to work properly. I have written about this in detail here if you are curious ->…

Should you elect to proceed with your purchase and find the adapter does not meet your needs or expectations we do offer a 30-day no-hassle return policy for all products sold by Plugable Technologies and fulfilled by Amazon.

Hopefully that information helps!

Plugable Technologies"

OK, thank you for the additional information. Your direct reply didn’t reach me indeed.
