it allows you to enable stage manager on an ipad mini without problems and without needing to jailbreak or similar :). the only gotcha is, that the ipad mini doesn't support more than 1080p output, therefore, if you connect a 4k screen it will remain blank.

would love to know if the ipad mini 7 now supports 4k - would actually be a meaningful upgrade then.
