Hello all,

since 2025.11 I have problems with my display. It is only Black, nothing is visible. With the latest 2025.10.5 all fine.

You can try this

display:
  - platform: ili9xxx
    model: ILI9488_A
    id: display
    dc_pin: GPIO42
    cs_pin: GPIO14
    reset_pin: GPIO38
    dimensions: 
      width: 480
      height: 320
    rotation: 270
    pixel_mode: 18bit    
    color_order: rgb  
    invert_colors: false
    auto_clear_enabled: true
    color_palette: 8BIT
    id: dispay

Hello Pepe59,

thank you for your idea, but it did not work, same reaction like before. Black Screen.

You probably need to configure PSRAM. And/or switch to the newer mipi_spi display component.
