how to change. a refresh rate with no picture

Hi 2am, my name is Rodrigo. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I am sorry to hear that.

You can reset the console to factory defaults via the troubleshoot menu.

This will start up your console in low resolution mode (640 × 480).

Before you continue, make sure you've got the account sign-in information. You'll need it to log back into your console after the reset.

With the console turned off, press and hold the Eject Button and the Pair Button on the console, then, press the Xbox Power Button to turn on the console.

Keep pressing the Eject and Pair Button until you hear a second Beep, then release them.

Your console should be booted into the Troubleshoot menu.

Turn on your controller and select Reset this Xbox > Select Reset and keep my games & apps.

If you are using an all-digital console (Xbox Series S or Xbox One S) you just need to press the Pair button, as there is no Eject button on them.

I hope this helps.

Had this problem contacted vizio and I had to uncheck the allow variable refresh rate in tv&display options on the Xbox one x and also had to turn off variable refresh rate in the pro gaming engine in the advanced picture settings.

How do I check if my tv runs HDMI 2.1?

I can’t change the refresh rate. No option to change it. My FPS is 60

completely incorrect again.

you do not need 2.1 for 1440p @ 120hz.

“If you have an Xbox Series S console, or if your TV doesn’t support HDMI 2.1, you can still enable 120 Hz gaming at a lower resolution. To do this, set your Refresh rate on the TV & display options screen to 120 Hz. If your resolution was previously set to 4K, the console will automatically adjust the resolution to support the 120 Hz refresh rate. Otherwise, select a resolution from the available options.
If you own an Xbox Series S and wish to game in 4K@120Hz, you’ll need to acquire a certified Ultra High Speed HDMI cable.”
