I recently bought the 50 inch h6570G. However, it seems that the UI is not even close to 4k, or, is scaled incorrectly. This is most noticeable in the Netflix app, where the show thumbnails and the subtitles are extremely blurry (the show itself looks sharp). I was wondering if there is any way to fix this? On another TV that I have (samsung ru7100) the native netflix app UI looks sharp and I was wondering if there is any way to fix this?
This might explain a lot for me. Aida64 says my display is 1920*1080 on my 4K TV. It seems like my Android UI is being rendered at 1080p
AFAIK, Netflix uses it's own subtitles for display -- the Android subtitles/captions are used for apps like system media player or those without their own subtitle support. Make sure with Netflix you are using the same user account / profile, as each one has it's own subtitle settings, and compare text from the same movie/series, as text is sometimes done as (text) subs and sometimes (image) captions -- the text subtitles are always sharper.
No way to fix it.
a 1080p Android TV user interface is standard for every Android TV device due to Google having to cater to both weak and powerful ATV devices, and that is called hardware fragmentation. Another inherent weakness in the ATV ecoSystem.
You are at the mercy of how good the picture upscaler of the 4K TV or media player itself is for non 4K source video content output at 4K
There is no true 4K GUI like you see on rivals Smart TV OS’s or the Apple TV 4K. I believe even Amazon”s Fire TV 4K devices also have a true 4K GUI.
