Android Tablet to run Digital signage?
I am a first time poster to the site, have read loads.
I am in a school and am looking at the possibility of purchasing a big(ish) TV and an Android tablet; my goal is to have the tablet run presentations, information, images and possibly student videos. I have done a limited amount of research, and obviously know that apple TV exists, but is there something similar for the Android, if so cost, technical know-how, and functionality. Any advice or understanding will be gratefully received and faithfully applied.
