Is Asus testing their firmware??? After updating the new firmware for the MCM 106 with and without a USB stick, the serial number is still missing and the error message "USB port is missing". I also reset the monitor manually and completely disconnected from the power supply. The error message "No serial number is displayed" and the USB port error is still there. According to the firmware, the error message should be "Fixed the issue where the model serial number cannot be displayed in the DisplayWidget Center".

Hey @Aureliannn_ROG looks like MCM105 was removed from the official site recently. Are there issues with the firmware? Should I downgrade?
Also, I'm still having the issues I highlighted in this post on MCM105. Is there an ETA on the fix?

MCM104 has also been removed from the official us/can websites.
Should we rollback to version 103 ? Is that downgrade supported by the monitor ?
Thanks

Genau das gleiche Problem mit MCM105, nach Downgrade auf MCM 103 keine Änderung. Seit MCM105 ständiges "Unbekanntes USB Gerät".
