I just purchased a TBT3-UDV dock on Amazon. I have 2 Dell UltraSharp U2715H 1440p monitors connected to it. One via Displayport and the other using this Displayport to USB C adapter https://www.amazon.com/gp/product/B07….
I am using the dock with my Dell XPS 15 9560 and also my late 2017 Macbook Pro 15. Both monitors seem to work fine with my Dell XPS 15 but only work sporadically with my Macbook Pro. Sometimes both work fine, other times the one connected via USB C will flicker, other times the one connected via USB C will not work at all, and other times the one connected via USB C will work fine but the one connected via Displayport won’t work at all. I tried installing the Displaylink drivers in case that had anything to do with it but it didn’t seem to make a difference.
Is there a way I can address this problem? If not, is there a dock that will reliably do what I want?
