I am trying to present a video from a third party app on my iPhone 6s (iOS 10) to an extended screen via the Lightning Digital AV Adapter. But sometimes it lags/jumps, making the video almost unwatchable.

Why does it do this? How can I stop the video from lagging and jumping?

  • What are you presenting to? HDMI output to a projector/screen? Do other machines lag when you plug them into the HDMI the same way (minus the adapter)? – owlswipe Feb 12 '17 at 23:13
  • Hdmi output to a projector screen. – Bartłomiej Semańczyk Feb 12 '17 at 23:14
  • If you, say, plug a computer in, does it still lag/jump? Do other apps on the iPhone have the lagging and jumping effect or just this specific third-party one? – owlswipe Feb 12 '17 at 23:16
  • need to check. Video jumps only at the end... It has 59 minutes... – Bartłomiej Semańczyk Feb 12 '17 at 23:17
  • That, to me, sounds like an issue with the app. I need to know more specifics (is it the iPhone, the app, the video, the adapter, the cable, or the projector, we must determine). – owlswipe Feb 12 '17 at 23:19
