NOTE : 

1. The name of the panel must begin with "edp-"、"lvds-" 、"hdmi-"  or “dp-”.

And it can be found in "kernel/include/dt-bindings/display/screen-timing/{LCDNAME}.dtsi" like :

lvds_g070vw01: lvds-g070vw01

2. If there is no configuration, you will get default setting :

hdmi-default  and dp-default as default setting.

3. Check your configuration in Terminal or debug console. 

cat /proc/cmdline
... prmry_screen=hdmi-default extend_screen=dp-default

Setenv in Debian (or Android) OS

Envtools are supported in debian and android os. You can change envs in Terminal or debug console very similarly in uboot.

Take "eDP + HDMI" for example:

IN uboot In Debian/Android
setenv prmry_screen hdmi-default fw_setenv prmry_screen hdmi-default
setenv extend_screen edp-1920x1080
 fw_setenv extend_screen edp-1920x1080
saveenv
