Visit the site of the maker.

A display port can't be used since the xbox one x only has a hdmi out

They can connect it the screen via HDMI as HDMI is one of the outputs on this screen.

However, you won't get 75Hz, the reason being that firstly the Xbox doesn't support 75Hz and two, there are no Xbox One games that run at 75 FPS. You'll get 60Hz instead.

If you're after Freesync it's a good idea to check out the manual for the monitor before parting with your money. You can find most manuals for monitors on the manufacturers websites. The crucial things you're looking for firstly is if FreeSync over HDMI
2.0 is supported, and secondly, what resolutions Freesync is available for use on the monitor. Not all monitors will support Freesync at 1440P or 4K resolutions.

I would suggest checking YouTube for monitor reviews regarding Xbox One usage. That way, you won't buy the wrong type of display.

In your monitor can you find a setting to enable Freesync?

Are you using the original Microsoft HDMI cable or at least an 1.4 or 2.0 cable? because if you are using an older version freesync can't work.

Hi,

This monitor only supports 100Hz over HDMI with FreeSync turned ON (higher via Display Port).

With FreeSync OFF this monitor does support 1440p @ 120Hz as per the Manual and LG support.

This makes means that with FreeSync ON you will be limited to 60Hz with xbox. Can you try turning off FreeSync via the Monitor and/or untick Variable Refresh Rate on the xbox. Hopefully this makes 120Hz available to you.

I have tried turning freesync off on the monitor side and vrr off on the xbox, still doesn’t allow me to select 1440p@ 120hz.

I can't find any FreeSync options in any of the display settings on the monitor, I've searched the menu for ages and found nothing, and also googled it.

I'm not surprised it's not working.

"When connected via DisplayPort, the 32GK650F has an excellent VRR range, but unfortunately, it has a limited range over HDMI, and FreeSync only works up to 100Hz."

Sorry about that.
