Dual monitor with USB 3.0 on Debian


New laptops mostly come with a single HDMI port. But I became quite addicted to a dual monitor setup.

It seems that HDMI -> 2x HDMI is not something which exists. Only to duplicate the screen.

USB 3.0 -> 2x HDMI adapters exist, but what about Linux compatibility. I am running Debian Stretch. Since this is for work I'd rather avoid Testing or Unstable. Although I don't object to install graphic drivers from Unstable or Experimental.

I know, it is a laptop so intended for mobile operation. I have a remote office where I work several months a year. I installed dual monitors all right but tried to avoid investing in a second desktop computer.

I have a docking station (or what is the official name of it) and I can use 2 monitors. It has 2 display ports and 1 hdmi.
I use ubuntu, but I think debian could be handle it too.

Gosh I must have been living under a rock for the past 3 or 4 years.

Thanks for the answer.

If your laptop has USB-C, look into the the Pioneer USB-C dock. It supports power delivery, doesn't use displaylink hardware (many issues with the drivers and linux), and is usually one of the cheapest that support power delivery (this was important for me). I love mine, and it was inexpensive.

It will also work with a USB-C to USB 3.0 adapter (I have one I took from my coworkers dock at work), but of course then you have to plug in your laptop in addition to the dock. Minor inconvenience but I wanted to avoid it on the laptops I have that are USB-C.
