HDMI Stopped working all if the sudden Xbox One X

It really shouldn't be a problem. Native res is 2560 x 1440 @ 60hz through the HDMI and that's what Xbox One X supports.

Plus, if it can work minutes at a time, why would it just go black all of a sudden? The link you sent was not helpful unfortunately but thanks for the reply.

This same thing just happened to me as well. It all of a sudden stopped working with hdmi cables, a/v cables, and doesn't work on any tv I have now. None of the settings were changed on the tv or xbox so I'm thinking it's in the system itself.

It worked and then all of a sudden it just stopped working.

Hi Dozey9937, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

Kindly perform an extended powercycle and reset your network hardware by following the steps below:

1. Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

2. Press and hold the Xbox button on your console for 10 seconds or until it turns off then wait for 2 minutes before turning it on again.

3. After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

4. If you are using a router, plug in the router and wait for all the lights to return to their normal state.

Thanks so much. I really appreciate the help. It worked after I did the hard reset.
