apple tv says unsupported mode when plugged into tv
My apple tv 4th generation has been working perfectly then all of the sudden it says unsupported mode on my insignia tv. the main screen of the apple tv will come up for a second then it will say unsupported mode. i have tried using a different HDMI cable and also tried to lower the resolution on the apple tv, because it will work on my other tv, and nothing is working. any help is appreciated. thank you
