The DisplayPort version is usually set to 1.4 but if you change it to 1.2, you may find that the monitor starts working again with your Mac. In LG monitors, if you go into the Settings > General you may can select DisplayPort version to get it working again. On MacBook Pros and iMacs that support True Tone, go to the Display settings and you simply uncheck the True Tone box to deactivate it. This is mainly on LG 4K or 5K UltraFine displays that support extending True Tone to them from your Mac. Some users have found that deactivating True Tone on the MacBook Pro display has helped to make external monitors work again with their Mac. You should then be able to see the refresh rate and change it manually. If you can’t see the refresh rate in settings, then try changing the resolution settings from “Default For Display” to “Scaled”. We recommend setting it at 60Hz if possible but you can try experimenting with whatever options are available to see if it helps. To change the refresh rate, you need to go to the Display settings on your Mac by going to System Preferences > Displays where you can manually change the refresh rate.

This seems to have been a problem from the release of Monterey and although the 12.1 and 12.2 updates have fixed it for some users, many still don’t work. Others are experiencing temporary black-outs which come and go or flickering. Some monitors are completely blacked-out in and not even charging the MacBook Pro connected by Thunderbolt cables.
The problem has also affected all brands of monitor including LG, Dell, BenQ, Asus, Acer and Xiaomi. This problem has affected both Intel Macs and the latest M1 Macs including the M1 MacBook Pro.
Many users have found that after upgrading to Monterey from Big Sur, one or more of the external monitors they were using suddenly stopped working with their MacBook Pro and Mac Mini.
