I am pleased to announce that I was wrong! The Lenovo TB3 dock does indeed output from both DP ports when connected to our Yoga 720 15. :catvery-happy: It also works to daisy-chain 2 monitors from 1 DP output.
I don't know the limitations of it, but I was running dual 2560x1440@60Hz. This was true when daisy-chained as well as using both DP outputs on the dock. I have a feeling it would do dual UHD, but not sure if it would be at 60Hz or 30Hz.
FYI, this was while the laptop screen was on and set to UHD.
Perhaps this dock could support 4 monitors if you had 2 daisy-chained to each DP output, but that's a big "maybe" and I have no easy way to test it since no one else I know has daisy-chainable monitors.
I didn't test it long, but I also hooked up my mouse and keyboard to the dock and they worked flawlessly. No driver updates or anything needed, just plug it in and it all works!
If you need dual monitors with the Yoga 720 15, I would look no further and GET THIS DOCK.
Shamelessly plugging B&H since they are $43 cheaper with free expedited shipping, and Lenovo fails at giving information, specs, capabilities, or even photos of the dock, so they don't deserve the extra money (the engineers of the dock do, but not the marketing or sales people, haha!).
I'm doing my happy dance now that I know the Yoga can drive my monitors and the temps are much lower after the repaste. I might get a cooling pad for it now for when I game on it at home. At work it won't heat up much so it'll just sit flat or in tent mode. I imagine tent mode actually cools well because of more room at the intake vent. I say that because I was recently watching reviews of the cooling pads with fans in them, and just setting the laptops on the cooling pad without the fans running would result in cooler temps, and turning the fans on often didn't improve it much.
