Can I please get some help on getting a monitor to work at 1440p AND 120hz?

Until you don't proof me this specific monitor (Xiaomi Mi Curved 34) enables 1440p@120hz with Xbox Series X, your comment is meaningless.

Yeah, there are some monitors with 1440p@120hz support for Xbox series s/x, that simply doesn't mean that ANY 1440p+ monitor with 120hz+ (especially 144hz+) can do it. Period.

I've tried everything, that (1440p@120hz) simply doesn't work with that monitor. I've already listed every step I've tried, I'm not gonna write it again.

Please read previous comments before posting the same dried comments...

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,

This maybe a limitation of the HDMI port on your monitor. Can you provide your monitor make and model please?

Note that the high refresh rates on most monitors only work at native resolution via Display Port as this is the most common way to connect monitors to PC's now. For cost cutting, the manufacturer may not supplied support for 120Hz at 1440P over HDMI.

But I need to know what your monitor is so I can look at it's supported display timings.

Thanks.

Hi neversatisfied415,

I’m about 99% sure there is nothing wrong with your Xbox One. The supported resolution and refresh rate is 1080P/1440P @ 120hz. It wont go higher than that. As for that Dell monitor, on these forums I have come across people having issues with getting 120hz
over 1440P on that model. Could it be that the feature was not activated via firmware? Only Dell Support can help you there.

I have been thinking about a 1440P monitor for a while now and so far my research is pointing towards the Gigabyte models where the user manuals state support for 1440p/120hz. I am waiting to see what resolutions are supported by Series X and if we finally
get 3440x1440 before commiting.

My suggestion is before committing to any 1440P monitor check the user manual to see if it clearly states support for 1440P/120Hz over HDMI. I would also be looking at newer released models of monitors (2019 onwards)

Hi,

I have the same monitor. The reason why you can't go to 120Hz at 1440P is because the LG 27GL850 tops out at 100Hz over HDMI at 1440P. This is why you can only do 120Hz at 1080P on this display.

My reasons for owning this monitor a little different to yours, it's main use is for my gaming PC which is connected via Display Port. Only on DP can this monitor reach its full potential.

Unfortunately, this is common issue amongst most monitors and we are getting quite a few questions on here with the same issue. Most Monitors have most of their full features reserved for Display Port.

The picture quality at 1080P is still stunning on this display though.

Thanks for the response!

That's annoying. I've heard that some people were able to get this monitor to run at 1440p 120Hz by disabling Adaptive Sync in the monitor settings.

I disabled Freesync premium in the Game Adjust menu and then tried but it still didn't work for me.
