: Xbox series x 120hz/4k

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

Well no the xbox series s isn't capable of 4k 120hz video games it's not even capable of 4k 60hz

That's the series x

The best the series s can do is 1440p

The reason why you aren't getting any signal is because the series s isn't capable of it

Only in streaming not gaming

This is the offical.ms.papers on series s

As noted it's only capable of 120hz on 1440p in games and 4,k 120hz on streaming

Not a lot of games support 4k 120hz even on xbox series x

Even on backwards compatibility games it's a max of 60fps with yakuza running at 900 frames

You gotta remember it's upscaled not native

Hence the lesser space requirements for series s

You don't need HMDI 2.1 for 4k on the Series X...you only need HDMI 2.1 to run at 4k 120Hz. The Xbox One X only ran on HDMI 2.0 but it output 4k perfectly fine.

For the Xbox one X you have to choose one or the other reguardless of the monitors specs. Either 1080p at 120hz or 1440p at 60hz. The Series X thats coming in November will support 4k at 120hz at the same time. 👍

Altough the Xbox One X supports 1440 and 120Hz, games are not going to run on 120Hz, console is not prepared for that yet.

So my best advice is to go for 4K HDR if your monitor supports it, and when the Series X is released, you will be able to use 1440/120Hz!
