Xbox series X 120hz option not supported even though I have HDMI 2.1

Hi,

Do you have the Xbox One, or the Xbox Series S? You'd be surprised how many people get the names confused.

If it's an Xbox One S, then that console doe not support 120Hz @ 4K. Also, the HDMI out on the Xbox One S is HDMI 2.0, not 2.1. Only the Xbox Series S and Series X support 4K @ 120Hz via the console settings. The One S is only 1080P.

Bear in mind also, that there are no games for the Xbox One S that do 120Hz (or 120 fps). The 120Hz option is only there to support VRR (variable refresh rate).

If you want to play 120Hz supported games, you will need a Series X. The Series S support of 120Hz games is a lot more limited.

Note that on the Qn95a, only HDMI 4 supports HDMI 2.1

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.

And what if I buy a cable will it work

The Xbox Series X will come with a HDMI 2.1 cable,

But whether you use a HDMI 2.1 cable or not, the HDMI port on the TV needs to be HDMI 2.1 to achieve the 120hz refresh rates at 4K.

using a HDMI 2.1 cable on a TV port with HDMI 2.0 will still only limit the Xbox Series X to 60hz refresh rates.

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.

Heres hoping that the Series X has support for 21:9 3440x1440 @ 120hz which I believe could easily handle it.

Series X will have HDMI 2.1 which has a bandwidth of 48 Gbps. By contrast, HDMI 2.0 is 16 Gbps. But you'll need an HDMI 2.1 TV/Monitor of course.
