Question [Q] Rooted Galaxy Note 3 Screen Mirror Issues

Hi. I recently swopped my Sony Experia Z1 for a Samsung Galaxy Note 3. I believe the handset is rooted. I only know this because one of my favourite apps wont work and i got a message telling me it wont work on a rooted device. My problem however is this. When i go into settings and connections and select the screen mirroring, instead of searching for available devices it just says empty.

This is very frustrating. The problem also applies to S-Beam and Kies etc although i dont really care very much for those.

Can anyone offer some advice as to why this is happening?

I should mention the phone is running Android 4.4
