Streaming Devices
I highly recommend an external streaming device if your "smart" TV doesn't have Google TV built in.
They have:
- better software and features
- more frequent updates
- more powerful/faster components (cpu, memory, storage)
- better support for high quality audio/video formats
- much cheaper than getting a new TV.
Options
I generally recommend the Google TV Streamer however all devices list below are good.
Premium
- Google TV Streamer https://tv.google
- Apple TV 4K https://www.apple.com/au/apple-tv-4k/
- Amazon Fire TV Cube
Budget
- Amazon Fire TV Stick https://www.amazon.com.au/Fire-TV/
- Kogan 4K Google TV Dongle https://www.kogan.com/au/buy/kogan-4k-smart-tv-dongle-with-google-tvtm-kogan/
- Xiaomi TV Box 3rd Gen
Buying at retail stores: JB-Hifi, Officeworks, Big-W and similar stores carry a range of the Google, Apple and Amazon devices.
