Series x keeps resetting with new monitor

Hi,Chris! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

Hmm that is so weird, a new output device should have nothing to do with the software malfunctioning.

Let´s first perform a full power cycle

Full Power Cycle

Turn off your console by holding the Xbox button  on the front of the console for approximately 10 seconds. The console will turn off.

Once the lights on the front of the console, unplug the power cable from the rear of the console.

Wait at least 1 minute

Turn your console back on by pressing the Xbox button  on the console or the Xbox button  on your controller.

After that test your console again

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.

The Xbox Series X will do 120Hz but no more, regardless of resolution or monitor.

I would check to see if other Xbox Series X owners have confirmed to achieve 1440p120Hz on those monitors before purchasing.

Maybe a google of "xbox series x 1440p 120hz ___________ " and insert the monitor model to see if people have posted about their monitor and Series X working.

In that case I highly recommend you see the monitor/TV in action with the console. That way you can verify that the monitor does support 120Hz on the Series X.

The Rtings website's reviews of Series X compatible monitors is a great way to start your search. These are professional TV/monitor reviewers, they test everything!

My input delay has gone I’m pretty sure. I used the power cable from series s and put it in my series x. I also changed my monitor settings and I think this worked. I hard reset my monitor and more options came up for some reason. Very strange
