MacBook Pro M1 and LG 34´5k2k monitor resolution 5120x2160 is not an option anymore

MacBook Pro M1 and LG 34´ 5k2k monitor: I have been running on resolution 5120x2160 but "suddenly" that resolution is not an option anymore? The highest I can choose is now 3840x2160. 

I noticed that text wasn't sharp anymore. Im using Thunderbolt cable and also tried another one. Any ideas?

Hi, yes it is a cable with their symbol. I tried another with symbol and "3" without any difference.

Byt yesterday; I called LG again and they said; Even though it sounds illogical, try changing the display port version setting from 1.2 to 1.4. Even if you are using a Thunderbolt cable and it is plugged into the Thunderbolt port, it may sometimes be interpreted as a display port cable. After doing that, all resolutions should appear. Illogical for me, but it worked :-)
