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.

Enter U-boot interrupt mode
Connect device to debug port, and open debug console. See more : How_to_debug.
Press "ctrl + c" key before power up the device, until get the following information on debug console :
Hit any key to stop autoboot: 0 => <INTERRUPT> =>
Then you can input the following cammand to config Multi-Display.
eDP + HDMI

| Port | RSB4710 |
| edp | edp-1920x1080 edp-1366x768 |
| lvds | lvds-g070vw01 lvds-g150xgel05 lvds-g215hvn01 |
| hdmi | hdmi-default |
| dp | dp-default |
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.
