The only way I know how to do this, will not stick after an OTA update, so you need to write down the steps, so you can reproduce it.
Open a terminal session (using putty)
type:
export DISPLAY=:0
sudo xrandr --query
This will return your display settings. The 2nd line will show the display port. in my example LVDS-1:
Fill the port in this line and run it from the terminal:
sudo xrandr --output LVDS-1 --auto --rotate left
If this does the trick you can add it to the kiosk startup script. Make sure you replace the xrandr line with the version that worked for you:
match='export DISPLAY=:0' && insert='xrandr --output LVDS-1 --auto --rotate left' && file='/opt/volumiokiosk.sh' && sudo sed -i "s/$match/$match\n$insert/" $file
