Personally, I just use my iPhone. I also have an iPad but I don't think that any of them have a bright enough display to use for FPV unless you are flying at dusk or something similar. I am not yet at the "phase" where I am comfortable enough to fly FPV but when I get there I will either purchase goggles (fatshark or equivalent) or a monitor designed for FPV. Again, this is just my opinion and I really don't have any data to give except for the fact that all of the Apple products I own don't seem to work well enough in sunny conditions. Sorry I couldn't be more help.
