I thought we were supposed to be able to stream in 1080p (3850kbps), but I never go above 720p (3000kbps) - according to the available example videos.
Check in the iPad's settings, under Device Info, and see what the resolution of the screen is. The screen has to be higher than 720p to get a stream higher than that.
Dazed and confused over high tech.
Sigh...Concrap. The Internet Overlord Cometh
They're not com-tastic!
Engadget says that they confirmed it would max at 720p on iPhone/iPod and 1080p on iPad (http://www.engadget.com/2013/10/03/netflix-5-ios-hd-video-airplay/), but it seems like all iOS devices are maxed at 720p.
While playing the test video today (to test something completely unrelated) I did (briefly) get a 1080p stream on my iPad air today, so I can confirm that it is possible. As to why we're all staying at 720p most of the time is still a mystery.
