Connect the Samsung DeX tablet or phone to the Targus DOCK419 for rendering the DeX desktop on an external HDMI TV or monitor of any size. You may have to select DeX mode in your device settings. DeX mode supports USB-C Alternate graphics for two screens at once. The local display of your Samsung phone or tablet is available while the DeX desktop is rendered on an external monitor connected to the Targus docking station. DeX can use the USB and Ethernet ports on the dock too.
Any Targus docking station models DOCK4XX or video capable adapter models ACA96X can be used for an external DeX desktop with any DeX-capable Samsung device. However, only a single desktop is rendered even when two or more monitors are connected.
If you are using any Targus docking station, you can run the DeX app on a host MacBook or PC. The DeX app can be downloaded directly from Samsung.
Targus DOCK190 remains the only truly universal docking station available in the world. As such, it is an applicable choice for running the DeX app on both macOS and Windows. This is recommended where the DOCK190 is used to build a workstation for highly productive users that may not necessarily be running DeX for all that they do.The same recommendation is true for any of the Targus universal docking stations using USB STD-A or USB-C, including Thunderbolt, for the host connection. These include models DOCK3XX and DOCK1XX. Connect the Samsung device to any downstream USB-C or STD-A port and start the DeX app on the PC or MacBook. There is nothing to keep you from running the DeX app on MacBooks and PCs connected with any Targus USB-C Alternate Mode, including Thunderbolt, docking stations models DOCK4XX and DOCK22X. The DeX app comes in handy for workstations configured with docking stations being used with various host platforms.
