2K 120Hz monitor no longer supported?

I have an Asus gaming monitor and had a similar issue; i turned of freesync and it seems to have fixed the issue using all the components that came with series s. When playing MW2 a window pops up showing refresh rate at 120hz, when playing NBA 2k drops down to 60hz as 2k doesn’t support 120hz. In the main tv/video settings it is set to 1440p and 120hz.

Hope this helps

Xbox One X supports 1440P and 120Hz or 4K and
60Hz. By attaching HDMI 2.1 or 2K@120 via HDMI 2.0. The cable will output just 1440P@120Hz only, in the end, this is a monitor that most suitable for PCs. Check the Video Output settings and tweak it accordingly. Your monitor, unfortunately, doesn't support
ALLM or VRR.

Good luck!

This article clearly states Xbox add 120Hz for 2K or 1440p, but why is it that I cannot get it to enable on my AOC AGON HDR 32in monitor?

Hello!

For 4K TVs, I think 120 hz with 2.0 hdmi is the maximum that the system will request. Now, for 8K TVs, 144hz with hdmi 2.1 it is necessary. So do not worry.

Hdmi 2.0 can only support 4K at 60hz or 1440p ( 2K ) at 120hz, Hdmi 2.1 will allow 4K at 120hz.

I'm also hoping that the console has a Displayport 1.4, for 4K at 120hz to use on 4K 144hz monitors

I'd like to clarify, you don't need a hdmi 2.1 connection unless you want 4k @ 120hz which doesn't seem realistic though i heard r6 siege will support that. Hdmi 2.0 can support 1440p @ 120hz and 2.1 ports are compatible with 2.0 hdmi ports and cords.

Odd thing that these monitors claim to support 1440p @ 120hz through hdmi 2.0 but for some reason don't on the One X, though there's a few that do. I read it's something to do with an unusual refresh rate configuration on one x that most monitors don't support,
so maybe the new consoles will have better monitor support since they're built with 120hz in mind, i guess I'll find out soon enough.

I'm just gonna buy a pixio 278 monitor that claims to be compatible with xbox (it's the one i wanted) and see how it is on next gen, if it doesn't support 1440p @ 120hz I'll return it and buy a px 329 which i know works on one x at 1440p @ 120, just no hdr
support, higher response, and apparently not that bright. Both affordable 2k 120hz monitors though. I'll update this if the px278 works on next gen or not aswell.

I appreciate all answers though.
