Default Support Display

Port	ROM-6881
edp	edp1-1920x1200 edp1-1366x768
lvds	lvds0-g070vw01 lvds0-g150xgel05 lvds0-g215hvn01
hdmi	hdmi0-default
dp	dp0-default
mipi	mipi1-gl0uan

NOTE :

1. The name of the panel must begin with "edp1-"、"lvds0-" 、"hdmi0-" “dp0-” or “mipi1-”.

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

lvds0_g070vw01: lvds0-g070vw01

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

hdmi0-default、dp0-default、edp1-1366x768 and lvds0-g070vw01as default setting.

3. Check your configuration in Terminal or debug console.

fw_printenv | grep display
... 
display0=hdmi0-default
display1=edp1-1366x768
...

LVDS Name	Resolution	Channel
lvds0-g070vw01	800x480	single
lvds0-g150xgel05	1024x768	single
lvds0-g215hvn01	1920x1080	dual

Using envtools in Debian/Android

Using envtools to setup envs in Debian/Android OS is very similar in uboot.

Take “eDP+HDMI”for example :

In uboot	In Debian/Android
setenv display0 hdmi-default	fw_setenv display0 hdmi-default
setenv display1 edp-1920x1080	fw_setenv display0 edp-1920x1080
saveenv
reset	reboot

Note :

The tool "fw_setenv" will save envs automatically in Debian/Android OS, so it isn't necessary to saveenv manually.
