Do I Need A Xbox Series X or S To Have 4K Resolution At 120hz?

You will need the Xbox Series X for 4K 120hz. The Series S can only do 1440p 120hz

Well no Series s doesn't do 4k

It can upscale video to 4k but generally you are capped at 1440p 90hz you can do 120hz at less resolution

The series s is underpowered for native 4k

It can't play games at 4k and will only stream media content at upscalled 4k

You would need ps5 or series x for 4k 120hz

And even then very few games will do 120fps Most will drop frames till people learn the next gen platforms

Cod and ea and ms or sony have no issues at those framerates though calisto protocol is bad for Frame rates

Most developers will only do 4k 60fps

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

What resolution are you trying to run at

If 4k 120 Hz then no it won't run at thaf

The max for series s is 1440p at 120hz

It will play at 4k bur only some games and with issues

The series s is meant for 1080p 120 max

With suggested 90hz

The xbox series x and ps5 and switch pro are the only 4k consoles

One x does 4k at 30hz and ps4 pro upscales

Microsoft claims that:

"4K games with 120 frames per second are available if you have all of the following:

an Xbox Series X console

an Ultra High Speed ​​HDMI cable with support for HDMI 2.1

an HDMI 2.1 compliant TV

To enable 4K games at 120Hz, press the Xbox  button to open the panel and select Profile & System > Settings > General > TV & Display Options. Make sure your Resolution is set to 4K UHD and set Refresh Rate to 120Hz.

Note If you have an Xbox Series S console or your TV does not support HDMI 2.1, you can still enable 120Hz gaming at a lower resolution. To do this, set your Refresh Rate in TV and Video Options to 120Hz. If your resolution was previously set to 4K, the console will automatically adjust the resolution to support the 120Hz refresh rate. Otherwise, select a resolution among the available options."

if you set the correct settings and not the image or it doesn't reach the 4k resolution it is not compatible to run in this resolution on the Xbox X series.
