Q: Screen goes blank when trying to mirror

I've got a 4th Gen ATV connected to a large screen display. Everything seems set up correctly, the ATV by itself works perfectly, and my MacBook Air on the same network correctly sees the ATV. But as soon as I turn on mirroring on the Air, the ATV screen goes black. For the life of me, I can't figure out where the problem might be. Thoughts?

    Try the following steps, check whether things are working after each step where appropriate, before trying the next.

     

    1. Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
    2. Check that both devices are on the same network (System Preferences > Network, on the Mac and Settings > General > Network, on the Apple TV).
    3. Restart the Apple TV (Settings > General > Restart).
    4. Restart the Apple TV by removing ALL the cables for 30 seconds.
    5. Restart your router. (Also try removing it’s power cord for at least 30 seconds)
    6. Restart your computer.

     

    If you are still having problems, try turning off bluetooth if it's enabled, also try using 802.11n for wifi if you are currently using either 802.11b or 802.11g. You might also try removing any other software related to screen sharing or streaming to remote displays that you might have installed at some time.

    You could also take a look at this UHD TV showing blank screen when Apple TV is selected on iMac thread, particularly regarding Mac firewall settings and Mac programs known to cause trouble for AirPlay.
