I am trying to use my phone data to watch movies and stuff and would like it on the tv..
I can watch youtube,vudu because they are apps on my tv and I can use the hotspot from the cellphone.
If I try to cast it requires router (same wifi)..
I would just like to use the cellphone and display on tv with out wifi hotspots.Just to display
What do I need to get this done..
Ive tried one item mhl hdmi and it was not compatible.
thank you so much for any assistance with this..
