Connecting a Acer laptop with Manjaro KDE with two Dell monitors with USB-C hub

Hi, I have an Acer Nitro laptop (details below). I am trying to connect it to two external Dell p2422he monitors that connect to the laptop with a USB-C. The monitors have internal hubs (dockers) in them.

The displays are not even recognised by the system. When I plug them in via USB-C:

  • Internet works (I have connected one monitor to the internet via ethernet)
  • Keyboard and mouse work (both connected to a monitor)
  • Charging does NOT work
  • The displays don’t work.

If I connect one monitor with HDMI it is recognized but I obviously want to connect via USB-C so I can have 2 monitors, ethernet internet, mouse, keyboard and charge my laptop.

I tried searching online but can’t find what I need to do. Do I need to install a DisplayLink driver or something similar?

please check the hardware-manual first. my acer-predator with that same bios isn’t able to support video over usb-c. this disappointing limitation is described in the manual.

Damn, I think you are right. I checked the manual and it does not mention anything about video over USB-C in the USB-C chapter. This is a gaming laptop and only 3.5 years old and doesn’t have this feature… I was able to set up a dock over USB-C but I had to install DisplayLink for that. Obviously the dock was specific for DIsplayLink, but would there be a similar driver for these monitors?

yes, that’s what i experienced with my acer too. and acer praised it as “THE gaming laptop” :roll_eyes:
