I have the https://plugable.com/products/tbt3-dp2x this plugable adapter - and it works great with my current P50 for a dual 4k@60Hz setup. I am changing my workplace and the other company got me a X280 - i checked the spec sheets (https://psref.lenovo.com/syspool/Sys/…) and it suggest i should be able to to - but i wanted to raise the question here and see if anyone already knows for certain. All help would be greatly appreciated. I do love my multi-monitor setup esp in 4K - the data density on each screen allows me to do my work A LOT more efficiently. Sincerely hoping i will not have to give that up.
Thanks for contacting Plugable support. I’d be happy to assist you.
Unfortunately we’ve not had a chance to test the Lenovo X280. Looking at the specifications that you linked to it has:
USB 3.1 Type-C Gen 1
USB 3.1 Type-C Gen 2 / Thunderbolt 3
It is unclear from the spec sheet if the USB-C port is data only or if it has video output. The reason this is important is that usually on systems with more than one Thunderbolt 3 / USB-C port, the video has to be routed from the graphics card to multiple ports. This can become a problem as to get two monitors over Thunderbolt 3, two lines have to be routed from the GPU.
We’ve encountered many systems where to simplify the design only one line may be routed to the Thunderbolt 3 port to allow for another line to go to a second USB-C or Thunderbolt 3 port instead. Designs to exist where these lines from the graphics card can be switched dynamically depending on what is connected, as an example HP Spectre x360s often do this.
With all of that said, unfortunately without trying the adapter or seeing if Lenovo knows, we have no way of knowing beforehand if it is going to be compatible or not.
Sorry that I can’t give you a definitive answer.
Thanks Joshua - I’ll test and share what I found out here in around a month.
I am intersted in the same question. Did it work?
