The Fire TV’s 4K HDR content looks stunning when paired with the right TV, making even scenes featuring three old men driving around in Amazon’s The Grand Tour look beautiful. Given the mess that built-in smart TV software can be, the Fire TV is blessed relief.
It’s worth adding here that one streaming device that does support HLG, the Amazon Fire TV 4K Stick, could actually only deliver the game in HD SDR because it doesn’t carry the Fox Sports app... Making all this look even sillier is the ease with which the situation might have been fixed.
It is worth remembering, of course, that if a 4K TV is fed a less-than-4K content source, it will have to upscale it to its screen resolution - no 4K TV will play an HD source in a completely pure form. If you have a high-end 4K TV, though, you may well prefer to trust the quality of that TV’s upscaling processing to that of the Apple TV 4K.
Naturally the Apple TV app will provide access to all of the Apple iTunes library of films and TV shows. However, while the app supports 4K and HDR10, it will not currently support Dolby Vision HDR or Dolby Atmos sound, even on Fire TV devices such as the Fire Stick 4K that can support both Dolby Vision and Dolby Atmos from other apps.
There are pros and cons to using a 4K Fire TV Stick with a non-4K TV, but it may be worth it to go ahead and get the 4K Fire TV Stick. With the additional features and the likelihood that it will eventually end up being used on a 4K TV in the future, you may find it to be the better option. Most people are familiar with 4K TVs and non-4K TVs.
Update: The new update on Fires tv stick 4k, (version 188.8.131.52) includes support for display mirroring through Miracast. Amazon recently released Fire TV Stick 4k, which comes with improved remote and support for 4K/HDR streaming. However, there is one big feature missing – the screen mirroring.
The Fire TV Stick 4K does support OTG USB cable splitters that allow you connect a USB device to its sole micro USB port, while still being able to power the device through the same port. You don’t need to root the device, as you did with the original Fire TV Stick, or anything special, for the OTG cable to work.
However, there is one big feature missing – the screen mirroring. Unlike the previous generation Firestick, the new Amazon Fire TV Stick 4K (along with Amazon Fire TV and Fire TV Cube) do not support native screen mirroring. This left a lot of us disappointed because I mainly use my Fire TV Stick 4K mostly to mirror my laptop on my old LCD TV.
