I changed the resolution to 3840×2160 by myself.

1, connect the TV by adb
adb connect xxx.xxx.xxx.xxx
adb shell
2, modify resolution by command wm
wm size 3840×2160
3 run app on TV
Done!

The resolution is still 1920×1080.
Is there a possibility that apps works at FHD mode and external input(HDMI) and codec of video work at 4k mode?

for clarification of the spacedesk viewer app settings:
if only “Use native android device resolution” option is checked
and
“Use custom resolution” option is unchecked,
then the resolution is only 1920×1080?
Yes. the resolution is only 1920×1080.

What is the model and Android version of the smart TV?
The model is SUPER3-X50 of LeTV. The model is made in China.
The Android version is 5.0.1.
