My LG Monitor supports 1440p @ 120 hz but xbox series x wont let me do it . Caps it at 1080 120

This worked on a xbox one s connected to a LG 32GN600

1. Goto Settings/General/Tv & Display options, under Advanced select Video modes and Uncheck everything.

2. Under Advanced select Video fidelity & overscan, Set Display Overrides to Auto-detect, 1440p 120hz will not be accepted with anything but the following -->Set Video fidelity Color depth to 24 bits per pixil (8 bit).

3. Set Resolution to 1440p, set Refresh Rate to 120hz, it worked for me.

After 1440p 120hz was accepted, the following could be changed:

Video fidelity, Color depth, 30 bits per pixil

Video modes, Allow variable refresh rate. (monitor confirmed)

Video modes, Allow HDR10

Video modes, Allow 4K. (In Halo Inf, HDR only worked with this checked, the monitor reported a 4K 60hz signal with HDR when playing, after exiting Halo the signal returned to 1440p 120hz.)

Note: A new Resolution 4K UHD, 60hz was added to the dropdown lists Only after doing steps 1,2,3 above (in that order) and checking Allow 4K. This option works on this monitor. Xbox upscales to 4k and the monitor downscales to 1440p.

Supported Hdmi Pc 1440p 120hz timings are HF183khz, VF120hz, P+/+

If you're not able to see 120Hz as soon as you select a higher resolution than 1080p

It's because the port in your monitor doesn't support 4K or 1440p - 120Hz

You may need to get a monitor with a 2.1 port

I don’t think you do i think 2.0 will work

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.

I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this CannonBallin316

What exact HDMI port do you have in this monitor? (1.2, 2.0, 2.1)

I ask this because in order to use a higher resolution at 120Hz you need to have a HDMI 2.1 port in your monitor

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.
