I solved the problem.

Main Display 1920x1080 Register Bpp = 16 Change OK!

I think there is not enough memory to display the screen.

Dear @tlfksh7,

Thank you for contacting support. There is configurable memory size for display buffer, could you adjust and try that? Details are here : https://developer.toradex.com/knowledge-base/display-driver-registry-settings#Settings_for_iMX6_Modules_Only
