A big problem is that Apple doesn't support MST even though it's part of the DisplayPort specification and Apple says they support DisplayPort over USB-C. As a result it's very difficult to create a dock that supports multiple displays on Apple devices. This is also why there hardly are any docks that support multiple displays. I truly don't understand this, it's 100% a software issue because it works when you install Windows on a MacBook.
Same here. After lots of crashes and problems connecting a monitor throught a DP to USB-C cable, I bought the TS3+ and this works much better. So far not a single crash, and everything works fine for me (Mac OS Catalina, MBP 16"). I use Gigabit Ethernet, displayport (4K monitor), some USB3 devices, and somewhere in the neighborhood of a bajillion USB2 devices connected via additional hubs.
if you are in clamshell mode, with display connected through the dock, will the display resume from sleep?
I have tried a number of TB3 docks (pretty much all except the caldigit), and they ALL have the problem (on MBP m1 at least) that the display will not wake when in clamshell mode. Display wakes fine when connected directly as USB-3 monitor.
Appreciate if you can test this and let me know :D
Using the Caldigit TB3 with a 2019 16" MBP in clamshell mode with two 4k LG monitors through the dock, I've found it pretty tedious trying to wake the monitors from sleep. Sometimes it'll take 30-45s of the monitors going in and out of power saving mode before it actually wakes up. This does seem to be the MBP's fault, because I can temporarily fix it by resetting the NVRAM.
Other than that, overall I've had a really positive experience with the TB3.
Before the upgrade to 11, wake was FLAWLESS. Since the upgrade, every 4th or 5th time or so, I find I need to cycle power on the monitor, and then the MBP finds it and comes alive.
Interesting - so it seems a big sur issue? Its my first dive into docks with the m1, and its REALLY frustrating trying to find one that works in clamshell.
Yes, at least with Catalina. I use my MBP in clamshell. And wakeup is reliable and predictable, more so than with a direct DP connection to a monitor, surprisingly.
Fully clamshell. I did find that the thunderbolt cable I used causes/fixes a significant number of issues though. Once I spent a year's rent on the Apple cable (which really does feel more substantial) it's been smooth sailing ever since.
