apple tv 4k resolution stuck on 576p SDR
Apple TV 4K model has worked fine with my 4K HDR TV for a few years. A few days ago, when powering off my Apple TV, there was a message that popped up about a problem changing the resolution. Now the resolution is “stuck” on 576p SDR. I’ve tried selecting any other higher end resolution and the tvOS software won’t switch to 1080p, or any 4K resolution that worked fine before.
Under “video & audio settings” check HDMI connection says there are no issues with my HDMI connection. also tried “reset video settings”, didn’t fix it.
also tried “reset and update” where it wipes all your settings and does a reset with the latest tvOS update (14.7) and that didn’t work either. Still stuck on 576p SDR.
any ideas?
