Problem

Certain tablets need to be given permission for wired projection once again, after the tablet screen is turned off and woken up.

Cause

After the tablet screen is locked, the signal output is disconnected, and the signal transmission link between the tablet and monitor is also disconnected. Therefore, when the tablet is woken up, the link needs to be set up again, and the authorization message for wired projection will display on the tablet.

Solution

1. This is a normal occurrence, and does not indicate any issue with your tablet. After waking up your tablet, touch OK in the projection authorization dialog box to project the screen to the monitor.
2. If the issue remains unresolved, feel free to contact Huawei after-sales personnel for assistance.
