Is anyone having issues with their LG 5k monitors where in "System Preferences > Displays" there is no option to rotate the display? I have reached out to Apple Support and they say that it is an LG 5k monitor firmware issue. Both MacOS and my LG 5k monitors have been updated to the latest version. I have attached a couple of images that shows how my settings look for the monitor and the system report for the video card. Edit: Added screen capture of one of the LG 5k monitors rotated using SwitchResX. You can see that the display is partially rotated and the black part of the screen is unusable. I will also like to point out that at some point, months ago, I was able to rotate one of the two LG 5k monitors and when I looked at the system report, under the Radeon 460, it did say that the monitor supported rotation. It just doesn't say it anymore. I even bought the Apple TB3 cables and to see if it was a cable problem, but I am still having the same issue.
