HDR colors are all washed out after update.

Add me to the list. I have a Vizio M55-D0, firing up Netflix causes washed out colors and is system wide until Netflix is exited out of. Even when playing an HDR title (Marco Polo) HDR isn't turning on and the colors are still washed out. Using SmartCast
HDR works just fine with Netflix.

I have this problem on my Samsung 65" KS9000. I will get a message from the TV that HDR content is playing and then the video goes dull/washed out. The TV video settings themselves haven't changed. If I view the TV menu or open an app on the TV, color
is normal. When I minimize GOW4 or Netflix, the Xbox dashboard is dull and washed out. If I open a non HDR Xbox app like Youtube, colors will go back to normal. Go back into Gears of War 4, Netflix or the Bluray player, video goes bad. Even adjusting in
game brightness/HDR and the TV settings will not help because the color is so bad.

I'm having the same problem with my Vizio P75-C1.

Netflix app shows washed out colors, and so does Forza 3 Horizon

Only UHD HDR Blurays are working... Very frustrating, especially after paying $99 for the early access to Forza.

I don't have that issue but my guide does also look washed out along with the game. Thanks for the info, will be sure to report it within the hub.

Hey Atom

Thank you for providing that additional insight for us.

As the most reset update for the consoles seems to have been strictly for Insiders, at this point we would have to recommend that you visit the link that Xbox Forums Ambassador AquarrzSudnnym
provided above for further updates regarding this scenario.

This would also apply to anyone else that is experiencing this same issue.

We will now be locking this thread as there is currently no other troubleshooting techniques that we can provide here on the Xbox Forums.

Thank you for being part of the Xbox Family and we wish you a wonderful day!
