Quick update: According to US Samsung support the US versions of S4 & GNote3 are capable, but will need SW update to enable in the future due to current licencing or other restrictions.
Norwegian & Swedish Support claims the European version will work. However the MHL 2.0 adapter is not yet available.
Just recently ordered the Minx NeoX7. I'll drop this for now and try to use mirracast with Samsung link to do the same through wifi.
