When I start the AIO-3399J board under Android 7.1 with both LVDS LCD and HDMI connected I get these messages in logcat:
- 01-18 08:50:06.452 419 558 I DisplayManagerService: Display device added: DisplayDeviceInfo{"Built-in Screen": uniqueId="local:0", 1920 x 1080, modeId 1, defaultModeId 1, supportedModes [{id=1, width=1920, height=1080, fps=127.000015}], colorMode 0, supportedColorModes [0], HdrCapabilities android.view.Display$HdrCapabilities@a69d6308, density 213, 320.0 x 320.0 dpi, appVsyncOff 1000000, presDeadline 7874015, touch INTERNAL, rotation 0, type BUILT_IN, state UNKNOWN, FLAG_DEFAULT_DISPLAY, FLAG_ROTATES_WITH_CONTENT, FLAG_SECURE, FLAG_SUPPORTS_PROTECTED_BUFFERS}

I can guess what the "HDMI Screen" is but is the "Built-in Screen" the LVDS ? If so why does it report "width=1920, height=1080" but in the DTS file I have horizontal & vertical set to 1200 x 800? I'm guessing there is more config to do but I don't know where to start.
Thanks
