I can say that I had an iPad mini 2 wifi only 128gb for this same purpose as a dedicated Mavic screen. And I was not happy. I got some serious screen lag and CPU overload warning... I believe it's cuz the mini 2 does not handle heat well. (I live in Phoenix, go figure). Other have had good success.... I also have an iPad Air 2. That works great, but it's too big IMO. So I sold the Mini 2 and bought the mini 4. I like it so much I'm selling my iPad Air 2. If your interested PM me.
