Please help, refresh rate option not showing on auto detect overscan. 1440p and 120hz is...

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+/+

Go to Fidelity and overscan in the video settings. Instead of auto detect, switch to hdmi. It will look blurry after changing, then go to your display settings and you should be able to select 1440p and 120hz.

On Video fidelity & overscan > Display > Please change "Overrides" to "HDMI".

On the previous screen, on "Display" you will see a drop down boxes for "Resolution" and "Refresh rate". See if you can now change it to 1440p and 120hz.

If you still cannot use 120hz, please confirm that you are using a HDMI 2.0 port and cable.

Sorry, I failed to mention: I'm on SX and the TV is hdmi 2.1 capable.

If I enable VRR, I can no longer use the motion smoothening, anti-judder feature so I need to keep that off and ALLM from the Xbox settings as well.

I do have to lower resolution to 1440p to enable 120hz by using manual override instead of auto-detect. That's odd I think, as the TV should show the two refresh rates available but there's no refresh rate option at all just 4k uhd, 1080p and 720p. When I do the manual override thing, I don't see 4k uhd as a resolution option although the 60hz/120hz option below that pops up!

Why is that though?

It depends on what resolution your going to play at and the resolution of the tv,

if 4K, you need HDMI 2.1 to get 4K at 120hz refresh rate,

HDMI 2.0 will only allow 4K at 60hz.

if your at 1080p/1440p, HDMI 2.0 will be ok for 120hz refresh rate, however if it is 1080p/1440p i would recommend getting the Xbox Series S as that is aimed at 1080p/1440p.
