Docking station that supports 3 monitors for MacOS & Linux (self.techsupport)
submitted 1 month ago by ApplyingAutomation to c/techsupport

Hey, I have two laptops & I'd like to get a triple monitor docking station that supports both of them, they are:

MacBook Pro - M3 Max - MacOS Lenovo X1 Carbon - 6th generation - Fedora 41

I got this dock: https://a.co/d/1vaXV11 and have been able to get it working with the MacBook, but my attempts to get it working with the X1 Carbon have been unsuccessful.

I can still return the dock if there are other suggestions? Thanks in advance

Can you daisy chain a monitor?

Does it work if you lower the resolution of all three?

I use a £20 lidl usb c to hdmi dongle for the first monitor and then plugging in the 2nd monitor via the laptop hdmi port.

This gives 2 monitors plus the laptop screen - I've not used a usb c adapter with 2 hdmi, so not sure if it would work for 3 external monitors.

My goal is to drive all of this off single cord.

It seems like that uses the displaylink tech. have you tried the linux driver? https://displaylink.org/forum/forumdisplay.php?f=29

An eGPU while costlier, is less cpu intensive, has one cable and with newish graphics card will have 3 or 4 outputs.

I tried installing the Fedora display link driver from here: https://github.com/displaylink-rpm/displaylink-rpm

It didn't work out of the box, I need to fiddle with it some more.

But, does M3 macbooks support egpus? My understanding was they don't.
