Options did not change - all by default. Version 5.41.1.
When loading from the SD card, the resolution is 720, as indicated in the file hdmi.sh.
But after flashing the image on emmc using the script nand_sata_install and downloading from emmc, the resolution is set to 1080.
In the load log I can see this:
