Xbox One X intermittent HDMI loss of signal

Randolph Savage · Apr 7, 2019

So about 1.5 months ago, I started running into an issue where my Xbox One X would lose HDMI signal when playing a game in HDR. Some nights, I can get through a full night of gaming (~4 hours for me) and no drops. Other nights, I can lose HDMI signal after
about 45 mins to an hour of playing. No real rhyme or reason that I can see why it's happening but I do notice that my HDR mode flickers a bit before the drops usually. Unplugging the HDMI cable and re-plugging seems to return the video signal or hitting
the XBox button and hitting A (to go back Home) sometimes brings it back as well.

Here's what I've done so far:

- Unchecked the YCC 4:2:2 option (it was checked originally)

- Switched from 8 bit to 10 bit and back to 8 bit again

- Switched to a new HDMI Premium cable

After switching the cables up, it seemed to do a bit better (still had some drops) but now it's dropping frequently again. I have a LG 65UH3060 model 4K TV and it's worked beautifully for over a year before it started dropping like this. I've seen numerous
topics on XBOX Support, Reddit, LG Support Forums with similar issues with both LG and Samsung TV's. Short of sending the XBOX in for repair, I'm not sure what else can be done at this point.

Hello Randolph!

I know how frustrating a situation such as this can be and I'm here to help! I understand you're having trouble with HDR on your LG 65UH3060 model 4K TV . I recommend you communicate with the manufacturer of the TV itself to get more information about their
device. You can also take a look at this helpful support article: Troubleshooting 4K and HDR on Xbox One
X and Xbox One S. If you determine that you would in fact want to send it in for repair you can do that here:

Let us know how it goes with a reply.

You can have the xbox sent in to see if that helps , but you should also have the tv checked or try on another tv to test it. It could be one or the other but you need to try another tv first

Yep, done on both accounts. I checked the last cable (the one that came with the One X) and no issues on the cable or pins. To fully rule it out, I switched it up to an HDMI Premium certified cable from Monoprice and still looking at the same issue which
helps to rule out the cable itself.

Yeah. I've heard that premium cables work better but that hasn't always been my experience.

Hi there Randolph,

Thanks for the replies. I'm sorry to hear about the HDMI connection issue with the Xbox One X and TV. Thanks for taking the time in troubleshooting with the step up above. Have you tried doing a

soft factory reset - Keep games and apps? This can help refresh the operating system.

If the issue persists, I recommend to
contact Customer Support
for further assistance or visit the Device service and Repair
site.

Hope this helps.
