The device I had a problem with is the Apple External Graphics Developer Kit's Sonnet branded external GPU case. I'm not sure if the fault lies with Sonnet or StarTech, but you'd think simple physical issues like correct connectivity would have been resolved with new-generation standards like Thunderbolt 3.
While my docking station is rated for 85W over TB3, my Dell XPS 15 7590 reports 65W max delivery, which is less than the 130W is is rated to carry over its dedicated charge port. Then again for most laptops most of the time 65W is fine. I have managed to get it to draw some from the battery while maxing out the TB3 link, but the laptop was also maxing out its temperature, which is not a good way to treat a laptop if you want it to last a while. I do have liquid cooled desk side computers, so my plan is to keep heavy lifting to those boxes anyways, so 65W is fine.
The end verdict is with the right laptop, this cable is plenty good for the job. I mainly knock off a star because it is a little on the loose fitting side to the point of causing problems where other USB-C style connectors work well enough. It seems to only be the case of where the connector on the computer / device is already a bit on the lose side with other connectors does this one push it over the edge to be problematic. In places where it is normally a tight fit, the extra looseness in stationary use seems to not be an issue.
My goal with this cable is to hook up a laptop that is off to the side to a docking station that is too far away for a passive TB3 to reach.
High Resolution--4K @60Hz, but USB speed is 2.0 <--Current setting
High Data Speed--USB speed is 3.1, but 4K @30Hz
I want 4K @60Hz _and_ USB 3.1 so that I can use the 4 USB ports on the display at full USB3 speed. Going through many discussion forums, I found that the DisplayPort capability needs to be 1.4 (HBR3), which my Mini has, and the link cable also needs to be capable of 1.4 (HBR3) and support DP-Alt mode.
A reddit forum specifically mentioned this cable--Startech TBLT3MM, which is a TB3 20Gb cable that supports DP-Alt mode--but apparently it's not capable of HBR3.
OSD menu shows
DP Capability: 1.4 (HBR2)
Dell cable works at 4K @60Hz (Link rate shows as HBR2)
Startech cable only works at 4K @30Hz (Link rate shows as HBR2)
USB speed is 2.0
High Data Speed
OSD menu shows
DP Capability: 1.4 (HBR3)
Dell cable only works at 4K @30Hz (Link rate shows as HBR2)
Startech cable only woks at 4K @30Hz (Link rate shows as HBR2)
USB speed is 3.1
I tried the same with an Intel NUC machine I also have (running Windows 10 Pro): Same exact results--I can't ever get the Startech cable to work at 60Hz no matter what setting I choose on the display.
This is unacceptable. The workaround I use are TB3-->DP cable and USB-A to USB-C cable to connect to he display.
The apparent build quality seems fine, and the cable is not as stiff as the Dell USB cable. But it will NOT do 60Hz ever. So no other choice but to return for a refund.
