I have some findings so far but not the solution: When i disconnect the display while booting the pi and den connect the display working (fine) ... im not 100% sure but its looking much much better maybe the resolution not 100% correct but color are good yet When i disconnect the display after booting in this "error" state and reconnect nothing changes Outputs of fbset: * On Error State: mode "1024x600" geometry 1024 600 1024 600 32 timings 0 0 0 0 0 0 0 accel true rgba 8/16,8/8,8/0,0/0 endmode * After disconnected startup before plugin display: mode "1024x768" geometry 1024 768 1024 768 32 timings 0 0 0 0 0 0 0 accel true rgba 8/16,8/8,8/0,0/0 endmode * After disconnected startup after plugin display mode "1024x768" geometry 1024 768 1024 768 32 timings 0 0 0 0 0 0 0 accel true rgba 8/16,8/8,8/0,0/0 endmode Nice so then i can set this supported resolution with "fbset 1024x768-60" -> NO -> ioctl FBIOPUT_VSCREENINFO: Invalid argument Then i try to make own mode in /etc/fb.modes with exactly the values from the working fbset -s output and after reboot try "fbset 1024x768" -> NO -> ioctl FBIOPUT_VSCREENINFO: Invalid argument What do i wrong ... Can anyone can help me with that? Thanks

Another 2 Hours with trying with fbset ... Nothing When i plug in this display in my desktop pc ist a nice screen with nice bright colors ... but on my pi it only garbage I love linux but wy its everytime so fu..... annoying when it is something with display / video / graphics ? Hopefully someone here has a hint for me what i can try :-) Thanks for Help

I have no Desktop i installed the CLI Version. I work only on TTY actual I have already try that link you mentioned ... Screen resolution on other boards -> Maybe outdated for bullseye or not applicable for my usecase ... i don´t find this example and when i try to set this in the boot.cmd with mkimage and reboot its not change anything xrandr not working from cli because of "Can´t open display" ... Maybe thats only possible when you run inside a xorg environment but i am on the TTY Did you have another hint for me?

Thanks for the reply ... but how can i do this ... I try some different solutions but i can´t see any difference to before: 1: Add Env Variables in armbianEnv.txt with different resolutions and different refresh rates -> same variables like here for raspbian described -> https://docs.sunfounder.com/projects/ts-7c/en/latest/settings_for_raspberry_pi.html -> Maybe the wrong variable names or wrong place? 2: Change boot.cmd with different hdmi settings and then "mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr" and reboot -> setenv display_autodetect "true" and "false" -> setenv hdmimode with different values Can u tell me where is the right place to change the display refresh rate or resolution? Can´t find the correct place Thanks

Hello, i have an Issue with my Touchscreen on my Banana Pi running Armbian Bullseye. The colors are not correct ... everything shows with a ?brown / red? touch and the Position are not correct ... Top 5 pixel border and bottom 5 pixel cut. I check the display ... it works fine when i plugin on my desktop pc ... so the hardware should be fine. Is there maybe anyone who can help me with that? I haven´t found a solution for this by myself or by google around. System: Banana PI M5 with prebuild Armbian 22.11 Bullseye CLI on internal MMC directly downloaded from the Armbian Website -> https://www.armbian.com/bananapi-m5/ Sunfounder 7" Touchscreen connected over HDMI and USB -> https://www.sunfounder.com/collections/touchscreens/products/7inch-ips-touchscreen AspectRatio: 16:9 Resolution 1024x600 Color 16.7M Chip on the Back (Maybe important): RTD2513A To Me: I have a some experience with Linux based systems (I use Arch on my Desktop and Notebook) but in this particular case i have no idea how to fix this or how to begin to debug.
