You cannot do it in Android Kodi because there is both no Auto Resolution switching on 99% of Android boxes and No Kodi dynamic refresh switching with the Mi Box.
You have to manually go into Android Settings > Display > Screen Resolution and manually select a 4k2K resolution yourself, to output 4K video at a 4K resolution. Even then you will very likely need a ASIX USB > Ethernet adapter unless you have a top spec AC WiFi home router.
Otherwise plug in a USB Hard drive / Stick.
