Hi!
It's DCI display and it's native resolution is 4960*2160 but there is no such option and the highest possible resolution for some reason is 3840*2160. I have to use SwitchResX to enable it. Why is this happening?
There don't seem to be more capable cables readily available.
this spec sheet says the expected maximum resolution when connected to a Mac (even the new Mac Pro) is exactly what you are seeing: 3480x2160@60Hz
https://www.lg.com/us/support/products/documents/31MU97%20Spec%20Sheet.pdf
it appears they do not expect Macs to be able to set the resolution of the display to its maximum.
Your SwitchRes solution may be the only way to proceed.

Thank you! I've just checked and the highest version (1.2) is activated. Interestengly, I found the same old topic and it was fixed in 2014 by OS update :-) LG 31MU97 4K Display not showing 4K on Ma… - Apple Community
LG article I found says:
INPUTS/OUTPUTS
what cables, adapters, and Docks are you using to make the connection? please mention EVERY item.
what Model-year Mac are you connecting?
what MacOS?
That cable should support the resolution you seek, however -- in some displays, you need to change the 'on-screen display' settings (inside the display, NOT on the Mac) to allow the highest version of DisplayPort, typically DisplayPort 1.4, because it needs to use data compression to achieve highest resolutions.
If DisplayPort 1.4 (with Data Stream Compression) is not an option, the data rates required to support that resolution are ferocious. Your cable/adapter must be top-notch, and under 1.8 meters in length.
¿what cable/adapter are you using?
I am using type-c to display port cable. Connected directly to Macbook's type-c port.
It's Macbook Pro 16 (2021), Apple M1 Max.
Monterey 12.6.2
Thanks!
I see. I have this one https://cabletimetech.com/products/usb-c-to-displayport-1-2-cable-4k-60hz?variant=42927639822594 1.8 meters.
Which cable would you recommend?
Thanks!
They provide special software to use some of the most advanced features. Did you install their software?
I somehow overlooked it. Thanks.
I think I tried thier software, but it didn't help. Thanks! I'll stick to SwitchResX
