I have a BananaPI M1 and I have installed the Armbian. The current resolution is 1920 x 1080 (px) which is very small. There is only 1920x1080 option in Settings> Display. How can I shrink this?


Armbian 5.35 Bananapi

Ubuntu xenial default 3.4.113

  • this completely unrelated, but how much big is your monitor? because 1920x1080 is ok with at least 24' monitors! Dec 3, 2017 at 16:06

First you must use this command to calculate the parameters you need to insert into xrandr:

cvt 1366 768

You can change 1366 768 as based on your desire mostly, use your favorite resolution. the above command will give you output something like this:

# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync

Copy the string after Modeline:

"1368x768_60.00" 85.25 1368 1440 1576 1784  768 771 781 798 -hsync +vsync

then insert it into the below command:

xrandr --newmode "1368x768_60.00" 85.25 1368 1440 1576 1784  768 771 781 798 -hsync +vsync

I think you using VGA monitor, so this command will assign this resolution to your monitors settings:

xrandr --addmode VGA1 "1368x768_60.00"

Finally you can active it with this command:

xrandr --output VGA1 --mode "1368x768_60.00"

Please remember THE VGA1 is completely based on your device! if you are using something else than VGA, replace this parameter with another value.
