Introductory

ROM-5780 surport 4 display ports : eDP、LVDS（mipi to LVDS）、HDMI、DP （DP to HDMI）. Only two ports work at the same time .

You can config Multi-Display to eDP + HDMI 、eDP + LVDS、LVDS + HDMI 、eDP + DP、LVDS + DP、HDMI + DP.

NOTE：

Android distinguish the primary and the extend screen.

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
LVDS Name Resolution
lvds-g070vw01 800x480
lvds-g150xgel05 1024x768
lvds-g215hvn01 1920x1080

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 prmry_screen hdmi-default fw_setenv prmry_screen hdmi-default
setenv extend_screen edp-1920x1080 fw_setenv extend_screen edp-1920x1080
saveenv  
reset reboot

Note :

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