RK3399 has 3 VPorts. 

RK3568 Vport.png

RSB-4810 surport 4 types display : eDP、LVDS、HDMI、MIPI. 

Note：

1. HDMI、eDP、MIPI MUST be set to port 0 and port 1.

2. LVDS MUST be set to port 1 and port 2.

3.  LVDS and MIPI are alternative.



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.

Default Support Display

Port RSB4810
edp edp-1920x1080
edp-1366x768
lvds lvds-g070vw01
lvds-g150xgel05
hdmi hdmi-default
mipi mipi-gl0uan


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

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.
