I can’t find which of the old ones definitely worked (because I bought 6 at once and didn’t manage to return the duds) and though it arrived on Sat, I haven’t had time to fully test the new one. It carried 4K/60, but I haven’t tested it across all our devices to be sure it does full power delivery to all. (If it only works on some, I have no problems sending it back until I get one that works well for all.) I’ll try to remember to come back and report on thread if I found one that works for all my devices (and what it worked for). It’s not something that I’ve time to carefully test during the week.

Thanks. So far I’ve ordered 3 cables and none work. The first one was a charging cable. I didn’t even know that was a thing and it’s when I started to learn about the differences between cables. My second one didn’t support DP Alt Mode which I seem to need. The third one was a 100W 4k USB Gen 3.1 that supported AltMode, but it just didn’t work reliable (that’s the one that results in the screen blacking out periodically. I’m thinking I should just spend $70 for the Apple cable because it will probably work.

  Your last paragraph annoys my frugal Yankee nature enough that it’s a long-last resort for me. On my personal desk setup, I don’t charge my Macbook in the same cable that carries video. My wife’s setup is a single cable connection (but she has an Air, so only a single external monitor). Working from home, I undock rarely, so two cables is not a problem for me, but I want a one cable for the kids who will dock/undock almost daily.

    I found a cable that so far (2 hours of use) has worked perfectly: https://www.amazon.com/dp/B0B1J7Z21J https://www.amazon.com/dp/B0B1J7Z21J I have my laptop (Lenovo P1) connected to my monitor. The one cable charges my laptop from my monitor (slowly) and displays 4k video.
