Xbox won’t display anything on multiple monitors and different HDMI cables and does not...

I'm having a problem very similar to what Claudia is experiencing. I tried Microsoft support and the online support for my monitor (Samsung, in my case). The only thing left to blame would be the HDMI cable that I'm using, but I've tried two different
cables on a total of three different TV's/monitors, and only on my monitor does the problem occur (with either of the two HDMI cables). If i unplug all other audio/video inputs from my monitor except for the xbox, however, there is no problem.

The xbox works fine on other displays, and my display works fine with other devices. Only when my xbox and my monitor are connected together do the problems start.

As I stated in my OP it won’t connect to anything via hdmi, we have tried multiple cables and TVs

Tried multiple monitors each with different HDMI cables including some that I know work.

It is possible that your HDMI cable is faulty, to be sure of this try using it on another monitor. If it does not work on that monitor then you should try a different HDMI cable.

Got a few questions so we can hope to identify where the issue is.

Does the TV act as if it's getting a signal, it just doesn't show anything, or does it remain unchanged when you power on the Xbox as no signal?

First thing to check is the HDMI source on the TV, cycle through and see if it's on a different input. Then, if available, try plugging the Xbox into a different port and see if it displays on a different HDMI input on the TV. If you have a different HDMI
cable, that might be worth trying as well. After, again if available, I would recommend trying to hook it up to a different display to see if it displays on there.

Those steps can help us identify if it's the console, the TV, the cable, or something else along those lines.
