The Apple TV has had several revisions since its introduction:
- 2007 1st generation
- 2010 2nd generation
- 2012 3rd generation
- 2013 3rd generation Rev A (first Apple TV to allow peer-to-peer AirPlay)
- 2015 HD
- 2017 4K (1st generation)
- 2021 4K (2nd generation)
- 2022 4K (3rd generation)
Our minimum recommendation for the widest compatibility with video formats, and to make sure documents are readable, would be to use the Apple TV 4K (1st, 2nd, or 3rd generation).
