Orange Pi 1: set size screen ? [solved]

Hi all,

First, thanks to Igor for his job with Armbian: Scripts, compilations etc. Very apprecied so far.

I own an Orange Pi 1 based on A20 SoC.

Armbian kernel 4.1.1 is installed, no problem. (I have used the Igor's script to upgrade it)

But I'm trying to change the bin file in /boot/bin, it seems to not work, no change if I set 

screen0_output_mode = 5

In orangepi.fex

Of course, I'm using the bin2fex & fex2bin exec on my desktop (Kubuntu 16.04 x64), and I copy the new bin file in /boot/bin/orangepi.bin

The goal is to change the first resolution, because I would like to solve this problem (see the photo, the display exceeds) on my DIY tablet.

Have you an idea to solve it (the bin file problem, or the size screen in general) ?

Thanks!
