I cannot find the app on the Play Store
The DisplayLink app is only available to Android devices running v5.0 or later. The APIs required by DisplayLink were added in Android v5.0, therefore it is not possible to use the app on earlier versions of Android.
Number of displays and resolution support
The app is currently limited to 1 DisplayLink display, operating at a maximum resolution of 1920x1080 (1080p).
My DisplayLink dock does not charge my Android phone/tablet
Current Android phones and tablets do not enable charging when connected to USB On The Go. As a result, when connected to a DisplayLink dock over USB, the Android device disables charging. This applies to wireless charging too.
DisplayLink is working with Android and DisplayLink dock manufacturers to enable USB docking and charging to be enabled at the same time through the same USB port.
My USB Ethernet port does not work
Android OS does not currently recognize USB Ethernet devices. The current work around is to continue to use the Wifi on your Android device while docked.
