One member on this site shared his “discovery” that the screen resolution while running RaspAnd (Android Lollipop 5.1 on Raspberry) can be changed by editing the file config.txt on the boot partition. This is so important/good that I had to write this special article about it.
If you open config.txt you will see these two lines
framebuffer_width=1280
framebuffer_height=720
I.e. change to (for example)
framebuffer_width=1920
framebuffer_height=1080
You will notice a big difference!
Hi, with full hd resolution, is too slow, i think with no overclock is better replace 1280×720 resolution
Thank you for this article it was really useful.
I try to setup config.txt for use HDMI display 800×480
I do some change but any of them work for me
1st try
framebuffer_width=800
framebuffer_height=480
2st Try
hdmi_group=1
hdmi_mode=87
framebuffer_width=800
framebuffer_height=480
3th Try
hdmi_group=2
hdmi_mode=3
framebuffer_width=800
framebuffer_height=480
Sounds like a touchscreen. Won’t work in that case. No kernel support.
