thanks for ansver, if it's not possible, I have to change my question.
Is there a way always to keep 1080p resolution in libreelec when no video is playing ? And once any video is played, resolution has to switch to 4k. I've tried to set 1080p in kodi and all white list to 4k - no success, autoframerate is not working in that case.

the reason why I need it - TV adds some uwanted processing when it handles upscaling to 4k itself, it looks like edge sharpen, it doesnt really looks good for those who wants best quality, I have samsung, but Im sure all tv's adds a lot of post processing for non native resolutions. That's not good when you're watching perfect 1080p remux for example. It's better if kodi or videodriver handles upscaling itself so you can be sure no processing is added
thank you
sorry for my english
