Xbox series x won’t do 120@1440p

I have the KOORUI QHD Curved 27 Inch Monitor, Fast VA Computer Gaming Monitor(2560 * 1440P, R1800, 144Hz, 1ms, DCI-P3 85%, DP+HDMI, Game Mode, Eye Protection, Rocker Button), Narrow Bezel on Three Sides and it only lets me do 120@1080p

Obsessive Power

From what I could find on the internet, this monitor has two HDMI ports, one of them (HDMI 1) is an older HDMI 1.4 port, while the second one (HDMI 2) is an HDMI 2.0 port. I can only suggest you reconnect the monitor to the second port and try again.

The fact that I had to go to a third party website just to find a manual for the R1800 doesn't inspire confidence in this display. The 'KOORUI' website wouldn't even open. Even if you connect to the HDMI 2.0 port, there is no guarantee this will allow 120Hz. Like most budget monitors, this display's main features will be locked into the Display Port which is for PC use.

It's quite likely you're going to be stuck in 1440P @60Hz.

What resolution are you trying to run at

If 4k 120 Hz then no it won't run at thaf

The max for series s is 1440p at 120hz

It will play at 4k bur only some games and with issues

The series s is meant for 1080p 120 max

With suggested 90hz

The xbox series x and ps5 and switch pro are the only 4k consoles

One x does 4k at 30hz and ps4 pro upscales

I don’t think this is true. I plugged my series x into a gigabyte 1440p 165 hz monitor yesterday after my 4k Samsung qled backlight died. I think HDMI only supports up to 120hz (the monitor cable is required for 165 hz). Going through an HDMI switch, I cannot do 1440p 120 fps, but it has no issue doing 1080p 120hz. After I get an upgraded HDMI switch and a better HDMI cable today, I’ll see if that allows 1440p 120 fps.

I'm wondering the same thing. I bought yesterday the asus VG27WQ1B. It's a 1440p 165hz curved monitor. My series x sees it as a 4k 60, 1440p 120, 1440p 60, 1080p 120 and 1080p 60 capable. Screen. If I select 4k and open the monitor osd, it shows 2160p 60. Even if I go to YouTube and open stats for nerds, the viewport shows 2160p. If I select 1440p 120 (the reason I bought it in the first place) and I go to calibrate hdr in the Xbox settings, the display automatically changes to 2160p 60 hdr on.

Definitely don't get no signal and like you said, "you wouldn't be able to activate a mode that your monitor doesn't support"

Did I accidentally just bought a monitor that has best of both worlds?

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