Got rid of all the Roku Ultras in my house and switched to Apple TVs. I’m using the Apple TV remote for TV power and after the first day or so there’s a huge delay in how long it takes to turn on the TV. Seems to be close to 30 seconds. I tried switching the control method from HDMI to IR for the Apple TV and that didn’t improve the delay. Any thoughts?
What brand/model of tv do you have? What are the display settings you have on the ATV? (Set the default to 4k SDR and turn on match content and frame rate I. The display options). Ensure the ATV has the control other devices option turned on. Make sure the TV has CEC turned on and that it has found the ATV through the discovery of new devices. This should allow your TV to turn on fastest.
