The only docks that have worked for me, have been the CalDigit TSX docks, which I have used for a long time. The TS4 is out of stock on the CalDigit site, and I'm never using Amazon again, for anything over about $100. I'll get it, eventually.
I have the latest 14-inch MBP (M1Max).
The biggest issues that I encounter are:
1) External keyboard wake up/recognized.
If I use a dock, the keyboard is often not recognized. I found that I need to plug directly into the Mac. Otherwise, it sometimes won't wake the computer, or the computer sometimes "forgets" the keyboard.
2) Monitor Handling.
I use a 49" LG Ultrawide (5120 X 1440). I used to have it split into two monitors (3840 X 1440, 1680 X 1440), but now use it as a single, ultrwawide, after Apple started natively supporting that resolution.
I found that many docks (even "Thunderbolt" ones) and adapters, refused to allow me to select the ultrawide size. Also, the monitor would often fail to be recognized, after the computer wakes, and I would have to reach under, and unplug/replug, to get it recognized. I have the monitor plugged directly into one of the TB ports, with a TB-to-DP cable, and it works great.
From what I understand, the new CalDigit should fix these issues.
