wfx01 Posted October 1, 2018 Posted October 1, 2018 hello i just installed Armbian_5.59_Tinkerboard_Ubuntu_bionic_next_4.14.67_desktop on a new tinkerboard s .. and ran myself into a corner immediately. i was trying to figure out how to get 4K 2160p resolution instead of HD 1080p. i changed the refresh rate from 60Hz to 30Hz and now can't get the display back. i tried reboot. and documentation at https://docs.armbian.com/User-Guide_Fine-Tuning/ said to modify /boot/boot.cmd and that file says "edit /boot/armbianEnv.txt to set supported parameters" .. . so i set disp.screen0_output_mode=1920x1080p60 in armbianEnv.txt no luck .. i seem to have gone headless earlier than planned .. advice pls? i was hoping to set this one up as a 4k streaming endpoint.
