Q: Cannot get picture on apple tv, can get sound with ios9

Hi alan120,

I'm sorry to hear you are having this issue with iOS 9 and your Apple TV. If you are having issues AirPlay streaming to your Apple TV from your iPad, you may find the information and troubleshooting steps outlined in the following articles helpful:

If you have a device that supports it, you may also want to test the streaming function by turning off your wireless router (assuming you are using one) and trying peer-to-peer Airplay, as outlined in this article:
