Airplay not working from macbook (works from iPhone)

[TropicalGent]

As above I have a UE65NU7100 and can use Airplay screen mirroring perfectly well from my iPhone XR. However, when I look at my macbook air (2015 version with latest iOS) there is no option to connect. It's like the macbook can't see the Samsung TV despite them both being on the same network! Very confusing!

Any ideas?
