Bought a led projetor, while not work fine with my TV Box?

Got my Tronfy Led projector, a brand heard less, while i noticed some flickering when i play movie with my projector via tv box. I heard that Android 5.1 is not compatible with some hardwares, so should i downgrade my Android 5.1 to Android kitkat, will that help? box review here, http://freaktab.com/forum/main-categ...v-telos-review
