hdmi wont read but work

Sometimes HDMI cables go bad for no reason. Also check to make sure you have it plugged into the right port on the back of the console. There is a HDMI in & out port.

Hi OozyChimp68,

sorry to hear. To help better, the error suddenly appeared or do you have a new TV? If the TV is new, some models offer a special game mode within their settings. Please take also a look here: "Troubleshooting
4K and HDR on Xbox One X and Xbox One S"

Hope this helps
