Hoping you can help me here...
I have an X380 Yoga with the USB-C dock. I bought 2 ACER monitors, each with 2 HDMI ports. Using HDMI-to-DisplayPort adapters, I have both plugged in to the dock, yet I can only get one of the monitors to actually display anything. This is all being with my laptop display in use, so I'm not sure if that is coming into play.
Any assistancce/insight you can provide would be GREATLY appreciated.

Hi blt4al! Welcome to our forums community. Are you referrring to this particular USB C docking station: https://support.lenovo.com/us/en/accessories/ACC100348? If yes, base on the setup and manual, you can only use 1 external monitor for the display port. You can use the VGA port for the second monitor. Please refer to the link below for the setup: https://support.lenovo.com/us/en/accessories/ACC100348 and the user guide here: https://download.lenovo.com/pccbbs/options_iso/tp_usbc_dock_sp40l36280_ug_en.pdf.

I have a Yoga X380 connected to a USB-C dock. When turn Yoga on either from the Yoga or the dock, the displays will not come up. Both external monitors are connected to the displayports on the dock. Now if you turn on the Yoga first and let it come up to a login screen before connecting it to the dock, when you make the connection all 3 displays come up. I have updated the dock and the Yoga and it is not working correctly. Does anyone have any ideas?

I read the documentation that was listed and could not find any information that, if you have 2 external monitors then you have to use one on displayport and the other on vga. Please clarify?

Thanks for posting in the Community,
Either one for Display Port and one in VGA port, or one monitor for each Display Port. May we know if you're using a VGA / DP connection for both the monitors or it is HDMI capable and you're using an adapter? Kindly download the Thinkpad Monitor INF File, Intel Thunderbolt Driver, and Intel Alpine Ridge Thunderbolt Firmware here,
Update us how it goes.

For troubleshooting purposes and to isolate the problem. Are the monitors working if plugged in directly to the laptop without the usb-c dock? Knowing the model of the usb-c could also help.
