Rk3188 armbian no hdmi output

Question

Hello. I have this old rk3188 based board with 32gb rom 1gb ram.

 

The arduino is attached for console output.

 

I wanted to install linux in it so i flashed rk3188 armbian to my sd card and it was able to boot up from sdcard successfully. But there is no hdmi signal.

 

I tried to modify dtb file extlinux.conf file but it didnt work.

  

Can anyone figure out what is the problem?

 

This is my extlinux.conf:

 

LABEL Armbian
  LINUX /boot/zImage
  INITRD /boot/uInitrd
  FDT /boot/dtb/rk3188-rbox-cs968.dtb
  APPEND root=UUID=61de6b0d-dcd6-4049-9fe8-3a15872992b5 console=uart8250,mmio32,0x20064000 console=tty0 coherent_pool=2M video=HDMI-A-1:e rootflags=data=writeback rw no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 bootsplash.bootfile=bootsplash.armbian
 

And this is my serial output from the board:
