How can configure i.MX7D developer board for Android Things to support 1024 x 600 tft display?

Please refer to the Section 6.3.2 "Kernel command line (bootargs)" of the attached document.

Have a great day,

Does the Android User Guide you specified also apply to the Pico i.MX7D developer board? I am not using Sabre.

I have updated the U-Boot bootargs as specified in Section 6.3.2 "Kernel command line (bootargs)" of the Android_User's_Guide.pdf document, however, the display resolution is not changing. Below is my U-Boot configuration:

=> print
baudrate=115200
bootargs=init=/init androidboot.hardware=imx7d video=mxcfb0:dev=ldb,1024x600M@60,if=RGB24,bpp=32 vt.global_cursor_default=0 consoleblank=0 rootwait ro loglevel=3 console=ttymxc4,115200 androidboot.console=ttymxc4 buildvariant=userdebug

After booting into Android, I am executing " dumpsys display | grep mBaseDisplayInfo" to get the Android display configuration. Here is the output:

mBaseDisplayInfo=DisplayInfo{"Built-in Screen", uniqueId "local:0", app 800 x 480, real 800 x 480, largest app 800 x 480, smallest app 800 x 480, mode 1, defaultMode 1, modes [{id=1, width=800, height=480, fps=53.742}], colorMode 0, supportedColorModes [0], hdrCapabilities android.view.Display$HdrCapabilities@1d6308, rotation 0, density 160 (160.0 x 160.421) dpi, layerStack 0, appVsyncOff 1000000, presDeadline 18607420, type BUILT_IN, state ON, FLAG_SECURE, FLAG_SUPPORTS_PROTECTED_BUFFERS, removeMode 0}

Android is still indicating 800x480 display resolution, which is the display that is included with the Android Things iMX7D developer kit, however, I need to connect a 1024x600 display.
