Hi, back a again for a question.

 

Got an 7" LCD Display connected to my pcDuino with Armbian (Kernel 4.x) and it displays nearly fine on HDMI.

 

First i altered display resolution in /boot(boot.cmd) but i still got "cutted sides" of the display...

 

On my Raspberry with Raspbian i had to alter /boot/config.txt with the foloowing content:

# Pollin 7 Zoll Display
hdmi_force_hotplug=1

framebuffer_width=1024
framebuffer_height=600
framebuffer_depth=24

hdmi_group=2

hdmi_mode=87

hdmi_cvt=1024 600 60 3 0 0 0
# Pollin Display Ende 

Where can i do that similar with armbian, think i have to change hdmi_group and hdmi_mode like i did with the raspberry, so that the LCD displays everything correct.

 

Maybe someone could help?

Yes, you change it by adding a (proper) kernel parameter to /boot/boot.cmd - you need to recompile boot.cmd to boot.scr at any change. 

 

I am not aware how nonstandard resolutions parameters are defined (at the moment) and if this is possible without fidling with kernel source.
