How to force? I've tried to change /boot/boot.cmd (then compile), but nothing...
like this
setenv video-mode sunxi:1920x1080,monitor=dvi,hpd=0,edid=0
saveenv
# Recompile with:
# mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
& like that
setenv video-mode sunxi:1920x1080-24@60,monitor=dvi,hpd=0,edid=0
saveenv
