I have just received my orange pi plus. Some question:

1)How can I write the lubuntu (or other distro) img on emmc?
2)How can I set different resolution and hz on lubuntu (it is blocked to 1280 and 50mz)
3)Why my monitor (that works with a hdmi2vga and works with my raspberry1 and 2) go black after some minutes (and i need to turn off and on)?

thx very much!

I think youll have to boot from SD card and then put everything besides the boot files for the distro onto the NAND. I think you still have to use the SD for the initial boot. im hoping you mean 50hz? Not 50mz. For that youll need to load up the config file with sudo whatever whateverso you can rewrite the file contents.

As for the lback screen it could be due to the improper resolution, or its due to 50hz instead of sixty. If your powering it by battery that could be it too.  

Yes hz. Sorry. what config i need to edit ?

Haw to do it ?

Yeah same issue here, I change it to 60hz on one monitor and when I plug it in another, it changes on its own back to 50...
