Second Screen, doesn't see signal.

79Red

Hi, I have a Dudu7 8GB RAM - 128 and 12 / 9.5" on 3.6. Please see screenshot for OS and version. DUDU OS 20250519/Model DUDU7 UIS7870 8-Core/8+218.

I have a USB-C screen that has full control thru touchscreen - it works when plugged into my PC and Macbook so I know it's works as a second screen, but when I plug it into the Dudu7, there is no signal and it does nothing. I've set up "Wired Screen" in Android setting and I've also rebooted the HU. How do I get this to work?

Thanks.

79Red Is there a USB video output option in the Android settings under Screen Mirroring?

Have you tried changing the resolution in settings?
