Direct answer
Yes. Apple TV 4K works with Samsung’s QN90D over HDMI. Apple specifies an HDMI 2.0-or-later cable for Apple TV 4K and recommends HDMI 2.1 to access all features. QN90D variants provide compatible HDMI inputs, and Samsung lists Apple AirPlay support as a separate built-in wireless option.
What this covers
- Apple TV 4K connected directly to a Samsung QN90D HDMI input
- 4K video with a cable appropriate to the selected format
- QN90D regional variants that list Apple AirPlay
What it does not cover
- ×Performance through an unverified receiver, switch or soundbar
- ×A guarantee for every HDMI cable marketed as high speed
- ×Country-specific app or Siri availability

Exact questions
Common follow-ups
Do I need an HDMI 2.1 cable for Apple TV 4K?+
Apple says HDMI 2.0 or later is compatible and recommends HDMI 2.1 to access all features. Use a certified cable appropriate for the formats you intend to use.
Can I use AirPlay instead of an Apple TV box?+
Samsung lists Apple AirPlay support on QN90D variants. AirPlay is a separate wireless feature and does not provide the same interface or app environment as Apple TV 4K hardware.
Why is there no picture through my soundbar or receiver?+
Connect Apple TV directly to the QN90D. If that works, the receiver, soundbar, selected HDMI port or cable path is the likely compatibility boundary.
