Xbox One Goes Dim A Lot When Watching Something

I've been watching movies through my Xbox One for over a year and everything has been fine. Today my screen goes dim roughly every twenty minutes and I have to keep on turning on my controller and moving one of the sticks to brighten my screen. Why has this
started all of a sudden? It's not a fault with my Xbox One because when I looked on the internet about an answer to this I read about a lot of other people having the same problem all of a sudden where their same problem started two days ago. Does anyone know
how to fix this? The screen is supposed to go dim when the Xbox One has been idle too long. Why is it doing this all of a sudden when we watch movies? I looked everywhere in my settings to disable the stand-by setting and I found nothing. Thanks.

After update, screen dims when watching Netflix

My xbox one is now having this same issue. Watching Netflix, 10 minutes or so later, the screen goes dim. This just started yesterday for me. VERY ANNOYING.

 

My Opinions, Thoughts and Concerns.

Did you have an Xbox 360, pkvas? The screen never dimmed while watching movies of any sort (Dvd, Netflix, Streaming media from PC..etc). It's only when idle and no action at all that it goes dim. If the 360 has the feature, why not carry that over to
the Xbox One. It's a pretty big deal for a lot of people. You might not understand it completely, but it is.

 

It's an automated feature with that can't be changed through the menus. It should only dim when idle like you say.....sometimes it can glitch and people have found that power cycling their console (by holding the power button in until the console shuts down
and then unplugging for a few minutes) can resolve the issue. Have you tried this since the problem started?
