Dtek50 screen cast

Must be a simple solution. When I screen share from my Q10 or Passport to my Samsung smart tv it just works flawlessly. When using my new Dtek50 the tv and phone are linked fine but the tv just shows the top left part of my phone screen in landscape mode and just a little strip of the screen in portrait on the right hand side. The tv is a 4k. Must have something to do with resolution on the phone. Any ideas?

Originally used wifi link. Then used Bluetooth. Then tried USB cable. Same result. The tv is 50 inch. If the screen was 6 times the size the picture would fit perfectly.
