Apple TV Screen Goes Black when Mirroring MacBook Pro
For some reason, when I mirror my MacBook Pro display on my Apple TV upstairs, it works fine. However, the Apple TV downstairs screen goes black when I try to mirror the display onto my TV. I tried to restore the Apple TV to factory settings and restarted it multiple times, however every time I try to mirror the display the TV screen goes black. I have a 2011 MacBook pro, an LG 70" TV, and I believe a 2nd or 3rd gen Apple TV.
MacBook Pro (15-inch Late 2011), iOS 8.3
