last time spend time on this and found a hint, that these tried options are not working for Pi3. :-(

-> try out lcd_rotate=3 instead of display_hdmi_rotate=3 in the config.txt

here it is stated that this last option would be only valid for touchscreens.

didn't work either.

here is another way:

video=HDMI-A-1:1080x1920@60,rotate=90

No, that's also NOT it.

Solution is much simpler:

These lines needs to be commented out:

#display_auto_detect=1
#dtoverlay=vc4-kms-v3d

then adding:
display_rotate=1

works.
