Change Resolution
Hi, I have a question.

I want to change resolution 1024*768 because I use 1024*768 touch display.

when I turned on the board installed Android 7.1 on this display, It was not showing the booting flow, and  showing the message "out of range". When using another display 1920*1080(FullHD), It is working well. 

I need to change default resolution settings before making OS img file. 

What do I change for changing default resolution at AOSP source?

Help me plz.
Hi Junseok,

Change resolution to 1024x768 60FPS can following below steps:

(1) su
(2) setprop persist.sys.resolution.main 1024x768@60
(3) setprop sys.display.timeline 1
(4) stop
(5) start

P.S. every time set resolution sys.display.timeline need to plus 1

Thank you for your question, as our new forum is online now, if you have any further questions, please join us on the new site.
