I bought this for my 2017 MacBook Pro
Everything is working except I have 2 HDMI Displays and it’s only working with 1 at a time. One display is going from the dock -> DP to HDMI adapter -> monitor. The other is dock -> USB C to HDMI adapter -> monitor.
Product page states: “Mid 2017 iMac and Dell Thunderbolt 3 systems can support an additional USB-C Alt Mode video adapter (sold separately) to provide a second display”. I bought this for the second display: https://www.amazon.com/gp/product/B06…
What works and doesn’t work:
-If I leave both monitors plugged into the dock, only the first will work.
-If I unplug the first monitor from the dock, the second one will work.
-If I unplug the second monitor from the dock, the first one will work.
-If I unplug the second monitor from the dock with the USB C adapter and plug it straight into the MacBook, both will work fine.
So clearly the dock supports both adapters just fine, but something is stopping them from working at the same time.
