My hdmi port seems to have failed on my Xbox series x

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

I would like to clarify, are you seeing "no signal" or just a black screen?

I had the same / similar issue with my old 4K 60hz none HDR / HDMI 2.0 monitor when watching movies and some times in games with the Series X,

As soon as i upgraded my monitor to a 4K 144hz monitor that has HDR / HDMI 2.1 ports, i no longer had this problem,

I'm not sure what the problem is, but my guess is that the HDMI 2.1 port on Series X doesn't play well with HDMI 2.0 port of monitors, or it's the Series X trying to force HDR on, even if the monitor does not have / support HDR and the HDR in Series X menu's is turned off.

I used the HDMI 2.1 port when i did my PC testing. I even tried different HDMI cables.

The issue is the Xbox One X system. Im wondering if Microsoft is able to fix that with a patch or softwarw update.

Doing some research, it seems the One X uses HDMI 2.0 which might be the issue. Im just concerned if I will have this same issue with the Series S/X that i pre-ordered.

Yes mate the Xbox Series X will have an optical out port, 2 HDMI ports, 2 USB-C port, Ethernet

And what if I buy a cable will it work

The Xbox Series X will come with a HDMI 2.1 cable,

But whether you use a HDMI 2.1 cable or not, the HDMI port on the TV needs to be HDMI 2.1 to achieve the 120hz refresh rates at 4K.

using a HDMI 2.1 cable on a TV port with HDMI 2.0 will still only limit the Xbox Series X to 60hz refresh rates.
