Black screen sometimes when mirroring my MacBook Pro through the Apple TV to my Samsung TV

When mirroring my laptop to my Samsung TV through my Apple TV, sometimes the video and audio start out find then after a few seconds the screen goes black. I've unplugged the Apple TV and TV for 30 seconds and it still does it. Video is fine for apps like Excel, Word, and general internet viewing but trying to stream a show on CBS.com it goes for a few seconds, then goes black. Audio continues though.


Thoughts? Is it network dependent, like CBS?

MacBook Pro 14″, macOS 13.6

I suspect you have a networking issue (first thing to try is to unplug your modem and router for 2-3 minutes, replug in and then test) where you are not getting consistent wi-fi signal strength. If your home meets any of the following parameters you may be ready for a home network upgrade:


  • Home is 1500 sq. ft. or larger
  • Multiple story home
  • Support 7-8 or more Wi-Fi devices (Apple TVs, computers, phones, tablets, lights, etc....)
  • Router is 5 years old or older.


If you home meets any of these parameters it may be time to look into upgrading your networking hardware, possibly a Mesh network.

Thanks for the tip rkaufmann87.


Ok, I turned off the modem, unplugged it, turned it on while unplugged to bleed off any energy, turned it back off while unplugged, waited 5 minutes and plugged it back in. Allowed it to boot up until it reconnected and tried mirroring and had the same results. Streamed video for seconds and then went black. Signal strength to the MacBook and Apple TV is good as they are only 20 apart.


I checked my internet speed on the MacBook and it was 16 mbps without mirroring and 10 mbps while mirroring. Could this be the problem. This is the top tier internet service in our area. Can't get better than this without going to satellite service. Shouldn't 10 mbps be fast enough to stream? It has been in the past.
