Xbox One X connectivity to my Monitor

I have my current Xbox One X connected to a 4k monitor, ALthough it does not have HDR so I might upgrade before the Series X comes out.

Xbox One X supports 1440P and 120Hz or 4K and
60Hz. By attaching HDMI 2.1 or 2K@120 via HDMI 2.0. The cable will output just 1440P@120Hz only, in the end, this is a monitor that most suitable for PCs. Check the Video Output settings and tweak it accordingly. Your monitor, unfortunately, doesn't support
ALLM or VRR.

Good luck!

4k support isn't a requirement to use a Xbox One X, it works fine on any TV/Monitor to which a standard Xbox One can connect to

Yes, you can use the Xbox One/S/X with a PC monitor with a hdmi connection. bear in mind though, if the monitor does not have speakers, then you will need to use a headset for sound.

The Xbox factory reset on the series X still did not work, it wouldn’t connect to the network. I connected my original Xbox one (2014) back up to my monitor and I was able to play online games just fine on there, same Microsoft account and internet that the series X was not connecting too. My Xbox series x keeps saying it has a hardware issue when trying to connect the internet, I’m pretty sure this proves it’s a physical problem with the hardware on my Xbox. I still have warranty on it and can return it and trade in for a new one. I’ll try doing this and seeing if the trade in one works.
