I'm also on the Dell "TB16" TB3 dock with Precision 5520 laptop. it's amazing all of this is working.
want to ask those of you who are running this combination...
i have dock connected two displays (over the HDMI and mini-DP)... it seems most reliable if i boot up with the laptop lid open and the laptop's screen kicks in first... then i actually do get output on both monitors, but they're mirrored and i don't see anywhere to separate and extend desktop across both... the laptop's built-in screen is actually properly extending.
my guess is that since they are exactly the same external monitor, the mac can't tell the difference? i guess i can just slap on a slightly different display model and prove that out... wondering if there's any insight along those lines?
thanks!
