xbox one s screen flashes colors?

My TV (LG 60UF7300) has the HDMI Ultra HD Deep Color as well. According to the Xbox One S support page, this is another name for HDR 10. Unfortunately, I've been having an issue with the Ultra HD Deep Color turned on. It's causing my screen to flash black
pretty frequently. It also says that HDR is turned off and that I can turn it on on a different menu, but the option is not selectable.

Hey there -

That doesn't sound ideal at all. Do you have a different display you can hook your Xbox One console up to? That would help us rule out your TV as a potential issue and narrow it down to your console. Also can you try a different HDMI cable? If you aren't
or you are able to determine it's a console issue vs a TV issue, the recommendation I have is the same - you'll want to try to

factory reset your Xbox One console. I know it's not an ideal step but I would recommend a full reset as opposed to the one that allows you to keep your games and apps. Hopefully that helps resolve the issue. Otherwise, you'll want to consider having it
repaired or replaced under warranty via the
Online Service Center.

Good luck and feel free to keep us posted!

I can verify this issue...Netflix UHD does not work on Xbox One S. I have a Vizio M55-D0 with the latest firmware enabling HD10 support. My TV is now recognized by the One S video settings as 4K HDR capable. I am able to enable HDR support and it works beautifully
with the Blu-Ray app (Mad Max 4K Blu Ray playing 4K, 24fps, HDR as verified by the Vizio settings app). However when I start Netflix, the screen flashes, colors mute, and video fails to switch to HDR or 24fps. Netflix app is clearly broken right now for HDR.
If I switch HDR off on the One S, Netflix app is fine, plays 4K correctly, colors are fine obviously no HDR.

Ok, I found lowering deep color setting may have helped a bit, but screen still flashes. Turning of deep Color on Onkyo didn't fix the problem completely.

Passthru on Onkkyo was only solution apart from not using Xbox tuner

Interestingly, if don't use tv tuner, 36 bit color works good on Xbox one (or app video and games only)

I.e. It is only the tv tuner output which craps out (even on main screen with tv minimized.).

Eg if navigate to preferences screen, the errors go away

So think the method of video overlay on Xbox desktop is defective.

So end solution was just to not use the tv tuner on Xbox one.

sorry for the late replay.i tried removing the HDD and starting it but still nothing happens.the screen is blank the controller just flashes and power supply color is light green.
