Hi,
i´ve installed the latest bananian image on my banana pi.
I´ve got an 14 " connected with hdmi on my pi.
When i boot the banana the screen is moved at the top and on the bottom is the first line which normally is on the top!
So i´ve to move the screen but i don´t now how.

If your picture is little out of screen you need a (new) different boot loader (2015.10) which support overscan.

Also Armbian does not have it by default yet since it's not stable yet.

Example of usage:
  1. setenv video-mode sunxi:1280x720-24@60,monitor=dvi,hpd=0,edid=0,overscan_x=10,overscan_y=5
Copy the Code

At the bootscreen the display is correct.
After Starting Kernel...the screen moved to the top and the first line shows on the bottom.
How can I configure overscan in bananian (latest release)?

Than try to fix / alter screen resolution in a kernel command line.

U-boot first try to set resolution automaticly from EDID and if fails than it goes for (i think) 1024x768.

Edit boot.scr and change it, than recompile.

Check this how-to. It's similar in Bananian.

You only can choose between valid / supported HDMI resolutions. Native display resolution might not be supported.

Thanks for your help.
I´ve tried to change the boot.cmd and recompile but nothing changed.
I´ve changed
disp.screen0_output_mode=EDID:1366x768p60
to
disp.screen0_output_mode=1280x720p60
but nothing happened.

On boot screen before Kernel load overscan shows (0x0)I think i need to configure the overscan parameters but as i know it is not possible on any image for banana pi!?!
Isn´t it?

Try.

It's probably possible but a little complicated. This command:

  1. setenv video-mode sunxi:1280x720-24@60,monitor=dvi,hpd=0,edid=0,overscan_x=10,overscan_y=5
Copy the Code
must be saved to u-boot environment because it's initializating before loading boot script ... with next boot you will have a working overscan.
  1. saveenv
Copy the Code
those two things add to the boot.cmd , recompile and reboot.

I´ve done your instructions but it shows still the first line of the terminal on the bottom with a black bar between the regular last line and wrong shown line.

In the foto you can see how it looks like.
