Any of those hubs will work with your Note 9, the only difference is what other equipment you already have. The ARKTEK hub is great if you plan to use a wired keyboard and mouse, the Uni cable should be used if you don't have a spare HDMI cable laying around, and the adapter from MOKIN is great if you do have an HDMI cable to spare.

How to use DeX with an HDMI adapter

  • Plug your HDMI cable into your monitor or TV.
  • Plug the HDMI cable into the hub or adapter, if necessary.
  • Plug the USB-C side of the cable, hub or adapter into your Galaxy Note 9.

    • That's it! The DeX interface will show up on your monitor or TV. If you are using a dedicated keyboard and mouse you can use those to navigate the interface. If not, you can use the Note 9 as a trackpad and use its software keyboard for input.
