App UI rendered at 1080p, even the display resolution is set to 2160p

I found that when I set the display resolution to 2160p, I can play 4k videos in real 4k resolution(I have a test video). But all the app UIs rendered at 1080p.


I used adb shell to check the physical size, it shows 1920x1080 whatever resolution I set.
I tried to use "wm size 3840x2160" and "wm density 480", the screen refreshed, but the UI is still rendered at 1080p(I have a test image).

I tried to run apps in a simulator of Android studio. It shows that when the physical size is 3840x2160, it rendered 4K UI well.

so, How can I render UI at 2160p? or is there any way to change the physical size to 3840x2160?  
"wm size 3840x2160" just set the "override size" and it doesn't work for UI rendering.

How did you know that your UI is 2160P? What method did you use?

I installed an app named Airpin, which can support 4K screen cast with airplay. I can dispaly a 4K picture in real 4k resolution via Airpin. How does it do it?

You mean this software can be used on coreelec, but not under Android

Can you provide us with the installation package of this APP for testing?

not on coreelec, just under Android. I can send you the APK. Do you have a email? The attachment has a size limit.

set the AirPlay resolution（AirPlay镜像分辨率） as 4K as following picture


and set the player(播放器/解码器选择) as internal player(hardware decoder)（内置播放器（硬解码））


then you can display a 4K Picture/video in real 4K resolution  via Airplay
