Which system do you use? Android, Ubuntu, OOWOW or others?
Ubuntu 22.04.3 LTS
Please describe your issue below:
I’ve got a small LCD display from DFRobot which has a rotated resolution of 800x1280. It works fine in Windows and on the Pi (albeit with some boot config tweaks). I’m trying to get it working with my Vim3 but I can’t get it to display anything. I’m hoping there’s a way to configure HDMI timings etc similar to how it’s done on the Pi (DFRobot wiki: https://wiki.dfrobot.com/10.1_inch_800x1280_mini_HDMI_IPS_Display_SKU_DFR0615)
