Back about 3 seasons ago you could simply use the NRL app and connect a hdmi cord and play it on a normal big screen tv( our big screen is not a smart tv)
In 2014 that was stopped by the NRL and I no longer could get it to work.
Last year , I was told by thr NRL that it couldn’t be used that way, but during round 1
I tried it again and Was able to watch ANY game each week,
All Foxtel games were able to be streamed to our big screen from our IPad if we wanted to( using the NRL app and AirPlay )
I wasn’t sure if it was still possible this season , so I tried it on Saturday, and yep, can still be done
AirPlay is plugged in to the tv , set your tv to the corresponding HDMI channel input ( open the ABC IVIEW app, on your tablet ( iview is the one that I use )) and open a show on it that’s supports AirPlay. (It will have the AirPlay icon)
Then start that programme and once it opens and starts. click on the AirPlay icon .
When it opens , tick the "AirPlay " option , then You will see the Airplay 4 numeral code come upon the big screen , enter the code on your tablet , And the screen will Then show the show that is running on your tablet. Go directly to click on the NRL app and go to the “watch live now” prompt on the game that you want to watch.
You can use the mirror option instead of the Airplay option on AirPlay if you want , but the Airplay option usually is better quality on mine.
Sounds complicated but is not hard once you’ve done it
There may be a better way of doing it, I’m not sure.
I only found this way accidently,
It works so I’m happy with it
