I am struggling to understand what could explain why the resolution for AndroidTV on the 58H78G, I just acquired, is stuck at 1080p.
When setting up the TV on the first start, the interface looked like 1080p (poorly) upscaled - you could notice the logos and text not being sharp.
If I start Youtube app, it renders 4k content clearly but when I go back to AndroidTV it looks blurry.
I tried running Kodi which confirms the system it is running on, has a resolution of 1080p only (visible under the System information of Kodi), which makes AndroidTV fairly useless for any extra app that cannot recognize a 4K environment.
I tried a few others apps and it looks like there is no native 4K rendering on this TV which if true is the most disappointing marketing move I have yet to see. The point of that purchase was to collapse TV and smart player in one product. I was curious (and maybe worried) to see the kind of system on chip such a TV would have. While I understand the TV is classified as budget, it is sad to see such a limitation on the user experience.
I have an NVIDIA ShieldTV (running AndroidTV 8.2) that I connected to the Hisense on HDMI and that player displays its interface as a 4K resolution (showing on the on-screen input resolution notification).
I have even enabled the developer mode in Android to try some recommendations around changing the size of the window manager and density which did not change the actual resolution.
For reference, in debugging mode over the network:

Which seems to confirm everything is running at 1080p for the launcher.
If I issue a 'wm size 3840x2160' command, the physical resolution remains the same, only the window manager changes which does not address the problem:
$ wm size
Physical size: 1920x1080
Override size: 3840x2160
I tried the the 'wm density' but, as far as I can tell, this is only for the way the ratio of the rendering looks like. I experimented a bit however, that does not address the native resolution.
Then the hwComposer section reports the following:

I am trying to understand whether the AndroidTV can run the launcher at 4K or whether the system on chip cannot handle that 4k resolution.
If anybody has any guidance on what else to check or try through ADB shell to confirm what I observed, that would be helpful.
The Android TV GUI interface is Max. resolution 1080p, because the Android TV OS itself has to cater to hardware configs both entry level and powerful like the Nvidia Shield.
If you also look at Stats for Nerds in the YouTube App it will also say Viewport “1920x1080”
It’s been that way since 2015. There is no fix or - reliable - wokaround.
4K video playback on a 4K TV running Android TV OS will be output at 4K, independent of the Graphic user interface 1080 resolution restriction.
Any externally HDMI connected media player will produce an onscreen Popup on a TV corresponding to the output resolution set in the Android devices display settings.
If the TV then displays 2160p that still does not mean the GUI used on the device is a true 4K resolution, but an upscaled 1080 > 2160p one. 4K video however will be output at 4K.
