Does 480p resolution work on your Apple TV 4K?

I’ve got two Apple TV 4K’s and some Sony Bravia TV’s all manufactured 5-7 years ago. I can’t get 480p resolution to work on either Apple TV 4K with any television I’ve tried it on. And I’m wondering how widespread this problem is.

This isn’t a problem I’ve seen with the Apple TV 4th gens. Only the Apple TV 4K’s.

i realize most people aren’t gonna be using 480p with an Apple TV 4K. But if you’ve got one handy, do you mind trying switching to the 480p resolution to see if the Settings app will let you do that?

To change the resolution, just open the settings app. Then scroll down to “Video and Audio”. On the page the comes up, either “Resolution” or “Format” is the top item, click on that and change the resolution to 480p 60Hz. Then wait five seconds to make sure the switch successfully takes place.

What happens on my Apple TV 4K’s is the resolution will successfully switch. But then you get a dialog box with a countdown timer. By the time the countdown timer gets to 20 seconds, the screen resets and I get another dialog box saying there was a problem and the Apple TV’s switching back to the old resolution.

If you try it for me and report whether or not the resolution switch was successful as well as the TV manufacturer and as much as you as you about the model off the top of your head (like maybe all you know is that it’s a Samsung about five years old?), I would appreciate it.

Thank you.
