Why wont my HDMI Cable work

Hi, Kaden! Thank you for reaching out.
I'm AJ, an Independent Advisor for the Xbox Community.
I'm sorry you are experiencing issues with your video signal.

• Would you mind giving this a try?

- If there's a disc in the console, eject it.

- Press and hold your console's power button until it shuts down.

- While the console is off, press and hold the power button and the EJECT button until you hear a beep to turn on the console. You’ll hear one beep right away and a second beep 10 seconds later. The power light will flash on before the second beep. Do not let go until the second beep occurs.

* If you have an All-digital Xbox One S or an Xbox Series S, you'll need to use the BIND button instead of EJECT.

• If that doesn't work, I'd appreciate your answering the following questions:

- May I ask which Xbox model you are using?

- Do you, by any chance, have a different HDMI cable you could try with your console?

- Have you already tried using a different HDMI port on your current TV/monitor, or a different TV/monitor altogether?

Thank you! I'll be looking forward to your reply.
Best regards.

I've done it all, will not work... I repeat, after an update yesterday, HDMI wont work, all hdmi cables work with all my other components except for my 360. This was After an update, only AV(Yellow, Red, White) cables work. No high definition on the console.

no it wont ! as i had posted before. This happen to two of my hdmi cable, they are different brand, my first one doesn't work. like you i thought changing it would fix it that why i bought the second one which mind you also doesn't work

I have FINALLY gotten my hands on another HDMI cable...................IT WORKS!!!!!!!!!! YES!!!!!

Can anybody here explain why that one HDMI cable can only work with anything other than my 360 or my Sylvania TV?

Different hdmi cable doesnt work and for some reason my xbox resolution is all blacked out and it wont let me even go on to it
