So my Xbox series X will not let me run 1440p 120hz with a 2560x1440p 165hz gaming monitor and the monitor model is Koorui 27E6QC 27in curved 2560x1430p 165hz VA panel. And im also using the HDMI cable that came with the xbox which should be a 2.1 HDMI. I've tried turning of freesync and everything but nothing worked.

paper drift
I couldn't verify from this page but its likley that it does not support this via HDMI at the same time. Just because a monitor supports 1440p and 120 does not mean both can be used togethor. It may also be refering too DP and not HDMI. https://koorui.co.uk/product/koorui-qhd-27-inch-curved/****
try turning off Game Mode though

I looked at the page and it says
Display
Screen ratio
16:9
DP 1.2
1440P+165HZ
HDMI 2.0
1440P+144HZ
response time
1MS MPRT
So it should support 1440p 144hz HDMI 2.1
And I don't think there is a game mode on it
paper drift
its a HDMI2.0 port and HDMI 1.4 as shown but that isnt irreverent

So would I have to use a HDMI 2.0 instead of 2.1
