# Install the DisplayLink APT package keyring # Download the Ubuntu APT package provided by, the official Mkdir -p ~/Downloads/Install_Files/DisplayLink I have tested my above instructions on Ubuntu 20.04, and the next instructions on Ubuntu 22.04, and they worked:įor Ubuntu 22.04 or later: # Make this directory if it doesn't exist, and cd into it Note: I think you first need to disable Secure Boot in your BIOS for this to work.įor older versions of Ubuntu: How to install DisplayLink software on legacy Ubuntu versions.įor my detailed instructions I wrote myself, see here: Full instructions: installing displaylink-driver on Ubuntu 20.04 (also applies to 22.04 or later). The latest DisplayLink driver supports Ubuntu 20.04, 22.04, and 23.04. They go back to Ubuntu 14.04 from 14 Jun. Legacy drivers are under the "Legacy Drivers" menu here. DisplayLink drivers are provided by Synaptics, the maker of the DisplayLink protocol and hardware DL chips, not by the maker of your particular adapter you are looking at, from what I can tell. You should download the latest DisplayLink drivers from directly here. Search the reviews for "Linux" and "Ubuntu". Reviews of the $90 Club3D CSV-1477 USB 3.0 Type A to dual 4k 60Hz adapter I mentioned above also state it works for Ubuntu, however. It explicitly says it supports Ubuntu, and reviews confirm this. This is likely the adapter I'm going to buy myself. Read about the different IC generations here, and ensure you know which IC your device you are going to buy has: Ĭommon inexpensive ($40) 2k 60Hz adapters like this use the DL-3500 chip and support resolutions up to 2048 x 1152 at 60Hz or 2560 x 1440 (2k, 1440p) at 60Hz. My monitor only supports 4k at 60Hz using the DP cable, not using HDMI. If you choose HDMI, be sure your version of HDMI supported by the monitor itself can support 4k at 60 Hz. I'm sure it's going to use quite a few extra CPU resources to make this happen, however. It may be lower resolution than this.ĭisplayLink over USB 3.0 on the latest DL-6xxx (ex: the latest DL-6950 SoC used by this device here) (on Amazon here for DP and here for HDMI) can support up to 1 video output at 5k 60Hz (5120 x 2880) or 2 simultaneous video outputs at 4k 60Hz (up to 4096 x 2160). Check the specs of the particular DisplayLink device you buy. Therefore, it also uses extra CPU resources on your computer, unlike the USB-C to video adapters above.ĭisplayLink over USB 2.0 is limited to a max resolution of 2048 x 1152, according to here: "Maximum resolution supported: 2048 x 1152". It uses special drivers you have to install on your computer plus a special "DL" DisplayLink hardware chip in the adapter, to force any USB 2.0 or 3.0 port to become an external video card. Expect it to be ~2.5~10x more expensive ($40~$150) than a comparable USB-C adapter, however. If your computer is older and has no USB-C ports, however, or if all of your video outputs and USB-C ports are taken up on your computer, or if you don't have an output built into your computer that can support 4k at 60Hz, then you can use a special proprietary "DisplayLink" hardware/software solution to give you more monitor output at up to 5k at 60 Hz using standard USB-A 3.0 ports.ĭisplayLink has been around since 2007, and is widely supported by a lot of adapters today. Amazon search for "usb c to HDMI adapter". Amazon search for "usb c to dp adapter".Since the video standards are built into the hardware and specifications, they are just plug-and-play, even in Ubuntu, and they take no configuration, no special drivers, and no extra CPU resources. USB-C video cables or adapters are cheap ($15~$30) and easy to find.
