Can you add the following to your autostart.sh and see if it fixes your issue?

Code:

FB_TYPE="$(grep '^0 ' /proc/fb | sed 's/[^[:space:]] //')"
sleep 2
if [ "$FB_TYPE" == "inteldrmfb" ]; then
  OUTPUT=`/usr/bin/xrandr -display :0 -q | sed '/ connected/!d;s/ .*//;q'`
  for out in $OUTPUT ; do
    # Hack - something is not yet fully right
    /usr/bin/xrandr -display :0 --output $out --set "Broadcast RGB" "Full"
    /usr/bin/xrandr -display :0 --output $out --set "Broadcast RGB" "Video 16:235 pass-through"
    /usr/bin/xrandr -display :0 --output $out --off ; /usr/bin/xrandr -display :0 --output $out --auto
  done
