  • Output on D3 & D7 screen appears distorted or incorrect

Contents


In some scenarios, the display of the expansion modules (D3 / D7) may display unintended anomalies (e.g. vertical lines or wrong texture). This unintended behaviour can be resolved with a firmware upgrade of your D3 or D7 to version 2.1.1 or higher.

We also recommend to use the latest firmware version on your desktop phone.

If the issue is still present after the upgrade, please open a Support-Ticket.
