Can Macbook Air (2017 model, Model Identifier: MacBookAir7,2 Part Numbers: MQD32xx/A ) supports 4K at 60Hz via Display Port to HDMI Adapter to AVR/TV

I would like to know whether anyone used it for 4K video playback through AVR + TV/Projector setup.

Which HDMI Adapter supports 4K playback ( I believe Display Port to HDMI adapter to be used for this). I found that many adapters are not supporting 4K and reviews of some of them are not good.

Is MacOS (Sierra) support bit-streaming of HT Audio through any applications?

Does this model support HDR in 4K?

Regards,
 
You will need to buy 4K capable adapter (check amazon) from Mini display port to HDMI. You will also need 4K Capable HDMI cable from there. It can playback 4K video, but I am not sure about HDR. For Audio, you can always perform passthrough and it should typically support bitstream. Upgrade to High Sierra as well. I recently bought this, but I havent tried 4K Playback as I didnt get the adapter.
 
Sierra can not bitstream anything higher than DD/Core DTS. Its a OS limitation.
