Apple TV not displaying iMac (late 2012) Mirror Screen

Problem: After extensive research in both these forums and youtube I have yet to resolve my issue when mirroring my iMac to my Apple TV via Airplay - the screen stays black when 'connected'.


Current set-up:


  1. iMac 27inch Yosemite 10.10.3 (Late 2012)
  2. Apple TV (Gen 3 Rev A)


Current Situation:


I have both my iMac and my Apple TV on the same network at home within 5 feet of each other (no room for wireless disturbance). I can access Airplay from both the systems preference > displays window and top bar menu, but I notice my AirPlay dropdown menu is missing the "Match Desktop Size" feature.

With Extend Desktop automatically checked off - all my HD Projector displays is a black screen until I hit the Menu button on the Apple TV remote to exit.


What is really the issue here?


I will try to see if my firmware for my router maybe the issue - but I highly doubt it.


Interesting Note: I can connect my iPhone 6 and iPad Mini seamlessly.

Apple TV (3rd generation), iOS 8.3

I got this problem today, immediately after installing (and briefly enjoying) Duet Display. If anyone else has the same problem, check that you don't have Duet Display or similar installed. I have a feeling that I'll need to uninstall Duet Display and hope it helps. For reference: http://help.duetdisplay.com/faq/124754-duet-is-installed-and-airplay-isn-t-worki ng-with-my-apple-tv
