Problem with video configuration after update

Hey, guys. I'm from Brazil so pardon me for my english not being perfect. When I bought my Xbox One, it was an automatic thing: the console would detect the resolution of my tv, 720 or 1080. Now, with an update, this is not automatic anymore, and I'm having
trouble. Because I play my Xbox on 2 diferent tv screens, one has 720 resolution, the other 1080. And when I forget to change the console to the 720p resolution on the 1080p screen, when I try to play at my 720p screen, I can't play. It was not like this until
an recent update. So I am kind of frustaded now, cause I have a lot of free time and I can't play my Xbox.

Press and hold the Xbox button and the Eject button until you hear a beep to turn on the console. You will hear one beep right away and a second beep 10 seconds later. The power light will flash on before the second beep. DO NOT LET GO until
the second beep occurs.

Note This will boot your console in low resolution mode (640 × 480). To reset this setting, go to System > Settings in the guide, select Display & sounds, Video options, and then TV Resolution.
