Title: video/screen resolution adjustment
Post by: FerociousRPi on August 22, 2018, 01:04:45 PM

Hello all,

I'm trying to adjust the video/screen resolution on my PiCore (RPiZ W). I searched several posts but could not locate any of the files listed below.

xsetup.sh
/etc/xorg.conf
/etc/X11/xorg.conf
lxrandr.tcz

Also to my understanding the Xorg doesn't seem to be the default installed. Thanks in advance.

Have you tried uncommenting the disable_overscan thing in your config.txt ?

Thanks but had to do some digging to find where the config.txt is located.

According to this post I have "black borders around the screen" which is a underscan issue. Will give it a shot. Thanks!

Thank polikuo, between you the the post I linked I was able to 'Mount /dev/mmcblk0p1' partition (which I could have done via the UI Bar) and made the changes with MC to '/mnt/mmcblk0p1/config.txt'. Uncommented 'disable_overscan=1' and that worked, got rid of the black bars.  Also adjust the resolution so things look larger by uncommenting:

framebuffer_width=1280
framebuffer_hight=720
