Unable to get 2nd external monitor to work with either mini DP or USB-C ports

Hey there, I am in the process of migrating from a desktop PC (worked fine so far with two 4k Philips PHL 288E2 monitors successfully for years) to a laptop-only setup.

I am using MEDION® ERAZER® Defender E15, AMD Ryzen™ 7 5800H, Windows 11 Home, 43,9 cm (17,3") FHD Display mit 144 Hz, NVIDIA® GeForce RTX™ 3050 Ti, 512 GB PCIe SSD, 32 GB RAM, Core Gaming Notebook | MEDION.AT since two weeks and I am unable to get my multi-monitor setup to work like before.

Connecting HDMI → HDMI works fine and I am always able to have one external monitor work with HDMI. Other slots for the 2nd monitor would be either mini DP or USB-C but the monitor never shows up or receives a signal. I verified this today in a computer store where I tried to connect all different combinations together with a store clerk.

I also have tried to boot from a Manjaro GNOME USB stick which suffers from the same issue. HDMI-connected display works, the other one with mini DP → DP doesn’t.

Tried with different kernels, X11 vs Wayland, already have the latest stable updates from today, ran commands that might have messed up stuff more, etc.
I am struggling with this for a while now, so really happy about any pointers to a solution.

Thank you in advance!

You should check the UEFI (or BIOS as we used to say back in the day) if there is some “security” active about the mDP port.

Hey mithrial, I checked the BIOS and haven’t found any settings related to mDP port. Other settings related to secure boot etc. are already disabled. Also note that I can’t have an external monitor connected through USB-C for some reason, so it’s probably not mDP-specific.

Also turns out that the 2nd monitor doesn’t work when booting from an Ubuntu ISO USB Stick…

So now it’s either faulty ports or hardware on the laptop or issues with my setup + linux.

I meant this
Why doesn`t my monitor show a picture on the USB 3... - MEDION Community

Oh, thats very interesting!

Unfortunately, my BIOS looks very non-standard, which gave me some headaches before already with disabling secure boot. Can’t seem to find that option.

For anyone who is reading this, I was able to solve this by:

  • switching to Ubuntu with Wayland
  • switching to open-source nouveau drivers
  • switching the cables of both monitors with each other

Now I have the setup with Laptop at 144hz and 2x eternal 4K monitors with 60hz working!
