As already mentioned, the compatibility of the new 4K Fire TV Stick MAX was particularly interesting for us. And not only in terms of the simplicity of device control in order to be able to easily control connected devices such as TV sets, AV receivers or speakers.
Rather, there was a not inconsiderable problem with the HDR format, which was delivered by Amazon Prime Video for UHD content. Our older 4K TV model from Sony from 2016 supported HDR, but apparently it was not up to date, which led to a very unsightly effect when streaming UHD content with HDR. There was a gray haze on the screen the whole time, similar to looking at the TV through a transparent dirty curtain all the time.
Strangely enough, this effect only occurred with Prime Video. With Netflix content, or with 4K HDR Blu-Rays, everything was good. Since we were definitely not alone with the problem, Amazon has now reacted and introduced the option that you can deactivate the HDR for the problem described above. Then you have “only” 4K resolution, but without HDR. In any case, it is much better that way, because before it was actually unbearable, and even with all the image enhancers and settings, it could not be solved.
