Everything flickers black when I start the Xbox

Hello, Tokishu. Thanks for reaching out! My name is Lucas, and I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

Did you already try to uninstall Xbox App from your PC and install it again? If you didn't, please try it and see how it goes.

Also, did this issue start as soon as you downloaded and started using Xbox App or it worked for some time and then it started to have this issue?

Are you using Windows 10 or 11?

Please answer these questions so I can better assist you, friend.

windows 11, yes, I tried to reinstall the Xbox (according to your own advice), I also reset all applications to factory settings. a problem appeared after some time.

Well, I can suggest you to try to uninstall and install it again to see how it goes:

First, see if Windows is updated:

Open Settings, click Update and Security and then Windows Update;

Click Check for Updates;

Click Download and Install Now option, if available (check for optional updates too);

After that:

- Completely uninstall Xbox App (and Xbox Companion App if you have it). Use their own uninstaller (just search for Xbox on Windows Start and click on uninstall).

- After uninstalling, go to Start > Type PowerShell > Right click it and select “Run As Administrator” > Type the following command and press Enter (you can run one at a time):

Get-AppxPackage Xbox | Remove-AppxPackage

Get-AppxPackage Microsoft.XboxApp | Remove-AppxPackage

Get-AppxPackage Microsoft.GamingServices | Remove-AppxPackage –allusers

(If you receive an error when executing any of these commands, don't bother. Just follow the other steps here)

- Press Windows + R and type in "regedit". Press enter.

- Search for HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

- Delete "GamingServices" and "GamingServices.net" (if they're still there).

Between matches on BF4 I hit the xbox button and then the screen flickered and went black. I could hear that everything was working fine but the screen was black.

what is your Problem?

Flickering Screen on Xbox

Flickering Screen on Xbox with HDR

Screen goes Black on HDR with Xbox ?

You talk about going black but have flickering on Topic.

There was an official Problem with HDR Flickering on that TVs and Xbox but that should be fixed a time ago

The screen flickers when HDR or HDMI ULTRA HD Deep Colour is on in the TV, after a while of flickering it goes black, then the TV loses the signal from the Xbox. That's
my problem.

If I deactivate HDMI ULTRA HD Deep Colour, then there's no more flickering and no more black screen.

Well it isn't fixed yet, I'm 100% sure I am on the latest firmware on both the LG C9 and the Xbox One X.
