XBOX One X no connection to TV (no HDMI output)

Did you make sure that the TV is connected to the correct HDMI port on the back of the console, there is two ports on the back of the Xbox One console one for HDMI in from cable / satellite TV box, and one that outputs the signal to the TV.

Yes thanks, console hdmi is in the output to tv port

Are you connecting an Xbox 360 or an Xbox One to the TV?

On some TVs, if an HDMI-connected device is causing a shrunken output, there should be a TV setting that adjusts "overscan", which adjusts the size of the output on the screen.

Hi, the xbox is connected to the TV with the original hdmi cable and the TV connected with the soundbar with hdmi/earc output

I will check but I do have an AV system which is setup up just like the Basic Set Up Guidelines specify:

Basic setup with an audio/video receiver

With an audio/video (A/V) receiver, the best and most direct option is to connect the devices sequentially:

1. Connect your set-top box HDMI output to the Xbox One HDMI input.
2. Connect the Xbox One HDMI output to your A/V HDMI input.
3. Connect your A/V HDMI output to the HDMI input on your TV.

Now I will have to see if the TV has HDMI output to include A/V if Xbox needs to go directly to TV or switch to optical
