Thunderbolt 3 Gen 2 Dock (40AN): Is the T480 (20L6) Compatible?

2019-04-01, 15:17 PM

Mates, has anyone been able to successfully use a TB3 Gen 2 (40AN) with a T480 (20L6)? I'm looking to run dual 4k monitors at 60Hz over the DP connections.


If they are not compatible, it appears I can use the TB3 (40AC) with the T480 using DP1 and TB downstream to drive both at 4k 60Hz, correct?


Many thanks for all help in advance!

Hi Bubbafrombama! Welcome to our forums community.
