I just bought a Thunderbolt 3 docking station with power delivery (TBT3-UDV).
I’m using it with a MacBook Pro 13-inch 2017 with Intel Iris Graphics 650. The MacBook is on High Sierra 10.13.4. I’m using the provided Thunderbolt 3 cable from the MacBook to the docking station.
I have a Dell Display with a DisplayPort cable and a Dell Display with a USB-C to HDMI cable from Plugable (Model USBC-HDMI-CABLE).
When I connect the docking station to the MacBook, only the display with the USB-C to HDMI cable works.
If I disconnect the USB-C to HDMI cable, the display using DP starts working.
Only when I reconnect the USB-C to HDMI cable both screens start working.
Every time my MacBook displays go to sleep, I have to disconnect and reconnect the USB-C to HDMI cable.
Is there a way to have both displays working every time I wake up my MacBook?
