Changing Apple TV Video Format
I recently moved to a mountain home so my internet speed is not good. In order to try to correct buffering issues I've been having with streaming content I tried to reduce the video format on the Apple TV 4K as an experiment. I dropped it down a number of times from the 1080p and ended up at 640 x 489 SDR. Nothing changed with the buffering so I'm now trying to return to the previous setting. Regardless of the format I try I get a message "There was a problem changing the resolution to ....". I've also tried the Reset Video Settings function and it didn't do anything. I've also tried unplugging the unit to no avail. The TV is a Samsung UHD which is HD and 4K compliant. What can I try to get my original settings back?
