My Xbox Series X doesn't send out the signal to TV.

Thank you for contact us! I'm Anderson, an Independent Consultant and a Microsoft user like you.

good evening

I'm sorry to hear that you're having trouble viewing your Xbox Series X on your TV. Here are some things you can try to troubleshoot the issue:

Check the HDMI connection: Make sure the HDMI cable is properly connected to the Xbox Series X and the TV. Check the HDMI cable or HDMI ports on your devices for visible damage.

Check TV input: Make sure your TV is set to the correct input for the HDMI port your Xbox Series X is connected to.

Restart Xbox Series X: Try restarting your Xbox Series X by holding down the power button for 10 seconds until it turns off, then unplug it and wait a few minutes before plugging it back in and turning it on.

Reset display settings:

If there is a disc in the console, eject it.

On your console, press and hold the Xbox  button for 10 seconds to turn it off.

Press and hold the Xbox  button and the Eject button until you hear a beep to turn on the console. You will hear a beep immediately and a second beep 10 seconds later. The power light will flash before the second beep. Don't let go until you hear the second beep or see the console boot into low-resolution mode (the Xbox boot screen will appear slightly pixelated).

Note If you have an Xbox Series S or Xbox One S All-Digital Edition, you will need to press and hold both the Xbox  button and the Pair button as your console does not have an Eject button.

Check for updates: Make sure you have the latest update for your Xbox Series X installed. Updates can sometimes fix display issues.

Hope these suggestions help!

When you say 4K pass through, are you talking about a 4K source sending the TV signal to the Xbox and then to the TV? Or sending the Xbox1 X 4K signal to pass through a 4K receiver and then to the 4K TV?

Update number 1, with a little more detail and the first failed solution attempt.

Hardware: Xbox series x, purchased brand new from retailer May 2023. LG television, 55 inch class 4k oled. Model OLED55C2PUA purchased new May 2023.

My issues include: Xbox powers up at 640 resolution on TV, x ox powers up and tv doesn't receive a signal from it, despite the TV activating when Xbox it turned on, signal drops out mid game with snow on screen like old school tv no channel snow, and when exiting a game to go back to the Xbox dashboard it loses signal. Unplugging and plugging back in the HDMI cable fixed the issue. Multiple cables and all HDMI ports were tried. Same conditions.

Attempt to fix 1: went with the optical HDMI cable mentioned earlier in this thread. This did not correct the disconnection/no signal issue. Therefore I can not recommend that as a solution.

HDMI repeater was suggested by another poster, that arrives today and will be trying that beginning tonight. The optical HDMI cable is not compatible with the repeater so I will be using top of the line HDMI cables. I will report back on the results.

For what it's worth, my series S has no problems connecting to the TV properly and does not lose signal.

That the Xbox Series X supports HDMI 2.1 doesn't mean your TV needs to support that too. You can user your old TV with the Series X for sure.
