Vizio's Twitter account for support questions supplied the information in response to a question from a MacRumors reader.
Apple recently shared a list of all AirPlay 2-enabled television sets on its HomeKit website, but only 2017, 2018, and 2019 Vizio models are listed.
From Apple's list:
- Vizio P-Series Quantum (2019 and 2018)
- Vizio P-Series (2019, 2018 and 2017)
- Vizio M-Series (2019, 2018 and 2017)
- Vizio E-Series (2019, 2018 and 2017)
- Vizio D-series (2019, 2018 and 2017)
2017 SmartCast models feature the same hardware as earlier 2016 models, which means the integration will work with 2016 TV sets as well.
Thank you for bringing this to our attention. We have confirmed that all 2016 4K UHD SmartCast Displays will support the Apple integration. -A— VIZIO Support (@VIZIOsupport) January 8, 2019
Vizio is one of the only companies implementing AirPlay 2 support on older television sets. Sony, Samsung, and LG are also enabling HomeKit support, but only on 2018 and 2019 models.
Samsung, for example, will support HomeKit on its 4 to 8 series TVs from 2018 and 2019, while LG and Sony are limiting the feature to new 2019 models.
