120hz not supported on Xbox Series X with a 144hz monitor

series x does not support 144hz, only 120hz.

Thank you again, last question, will the xbox series X be able to support 144hz for monitors?

No, they will be capable of 120hz over HDMI 2.1 if you have a monitor with HDMI 2.1,

But, as of yet, there are no gaming monitor with HDMI 2.1,

The first gaming monitors to have HDMI 2.1 wont be available until the end of this year to early 2021.

for 120hz you need i think hdmi2.1.

besides connecting the s at 120hz is not going to magically let it run at 120fps, you will be lucky to get 40fps on most games. kills my eyes running so slow.

HDMI 2.1 is only needed if you plan to game at 4K for 120hz , on a 4K 144hz monitor, However there's no gaming monitors available at the moment, that yet has HDMI 2.1, the first HDMI 2.1 monitors that are likely to come in are around the same time as the
Series X (Q4) launch or early 2021 (Q1),

1080p and some 1440p monitors can do 120hz over HDMI 1.4 if it's supported, but best ideally is HDMI 2.0 for 1440p for 120hz,

HDMI 2.0 can do 1080p / 1440p at 120hz and 4K at 60hz,

HDMI 2.1 can do 1080p / 1440p / 4K at 120hz.

For the Xbox Series X, it best to get a 4K TV or monitor that supports 120hz and has HDMI 2.1, to get the full potential out of the Series X.

Hi,

Do you have problems with getting your Xbox to use your display's 1440P resolution and 120Hz on this monitor?

Your monitor has a note in the manual that says:

* When HDMI Compatibility Mode is on, 2560 x 1440 @ 120/144Hz resolution is not supported.

I would assume you should be able to get 120Hz at 1440P with this monitor connected to a Series X. But, as you've probably seen, the Xbox One can be really picky when it comes to monitors.

Monitor interest has gone up considerably since Microsoft released support for both 120Hz and FreeSync. The problem is getting a monitor that will use these features correctly over HDMI.

It sounds like any monitor that uses non standard Vesa frequencies (144hz as opposed to 120hz) will not be able to effectively run at 120hz with 1440p on xbox one x.
