using your iPhone as a remote is incredible as I can never find the remote especially with my kids. I have one in ever room, 4 rooms and my phone can easily switch to control all 4. Make sure you set it up right with the right hdmi cord to the arch hdmi so you can control volume from your phone. You can even use your find to Find you remote (similar to find an AirTag) with new software update. When you put your airpods in the apple tv has a pop up that says to you want to switch auto to airpods… which is really cool. But, sometimes I’m watching tv at night and my wife starts to fall asleep, so I use this shortcut:
From the Apple TV’s home screen, press and hold down on the Play/Pause button on the Siri remote. After a few seconds you’ll see a screen like the one above. Simple select your bluetooth headphones and boom!
And second I set an accessible shortcut to reduce white point and it reduces the brightness of the tv screen. The shortcut for that is triple click the < button on remote or from iPhone control center remote its holding home button and selecting accessibility
Lastly, i love that how ever i configure the app layout on the screen, each tv in the house syncs and shows the exact same layout.
Love my ATV i have two HDs, and two 4k 2nd gen. Trying to find an excuse to get 4k 3rd gen.
