Why can’t I run 1440p at 120hz on Xbox series x?

That doesnt answer the question is it going to work for older monitors that are hdmi 2.0 that didn't run at the 1440p 120hz they were supposed to run at on xbox one x i bought a viotek monitor gft27db was supposed to run 1440p 120hz over the hdmi 2.0 but
it doesn't on the one x only runs at 1080p 120hz with freesync on or 1440p 60hz no freesync will series x solve this issue thats what he wants to know i have heard it was a bandwidth issue but with the new console having higher bandwidth i would guess it would
solve the issue but would like to know for sure

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

Hi ! Do you know if Xbox series X will support and run in 1440p/120hz with a MSI Optix MAG27CQ ?

Thanks for your help

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

https://www.xbox.com/en-CA/consoles/xbox-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

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.
