EugeneC Posted February 25, 2019 Posted February 25, 2019 Any news on support for LVDS LCD screens? I am using s430. It is awesome screen, sun readable, capacitive touch. During boot I can see logo flash in a corner. Looks like screen resolution is passed wrong or not detected properly. Thank you
eduards66 Posted May 22, 2019 Posted May 22, 2019 Is somebody has success with LVDS display s430 for nanopifire3 with armbian distribution 4.14. Any help is highly appreciated.
