Hey @arkimede,
I asked directly for your screen details - manufacturer, model, or a link to the tech-specs. You responded with configuration files only.
Without knowing what hardware you actually have, I cannot help. Configuration files tell me what you configured - not what display is connected, how it connects, or what parameters it actually requires.
Required information:
- Display - manufacturer, model number, connection type (HDMI, DSI, SPI, other), link to product page or datasheet
- Raspberry Pi - exact model identification per the guide: [GUIDE] Identifying Your Raspberry Pi Board on Volumio: A Comprehensive Guide to Revision Codes
- Log link from http://volumio.local/dev or http://<IP address>/dev
A 1280x400 resolution could be dozens of different displays with completely different configuration requirements. Guessing is not troubleshooting.
No screen details, no Pi details, no log - no help.
Kind Regards,
