how to get screen rotation to work (portrait mode)

I'm running :
ro.fota.device=NEO-X8H-PLUS
ro.fota.version=KOT49H.20160114 release-keys

I have changed build.prop for

ro.sf.hwrotation=270
ro.sf.lcd_density=240

have tried (but doesn't seem to make any difference):
const.window.w=1080
const.window.h=1920

Rotation works but, everything only shows in top half of screen. I'm looking for portrait mode, but can't quite seem to make it happen. Worked on X7s ...
Any ideas?
