Mac Big Sur 11.3.1 (May 2021) update has broken the 4K resolution of my monitor (using DP interface) - I am not able to scale to anything more than 1920x1080 - using Plugable USB-C Triple dislplay 4K Docking Station

FYI: Prior to the update - using v11.3.0, it worked OK

From reading these forums, flipped the connection to HDMI - which DOES work to 4K resolution...
Ordered a DP to HDMI cable, and will report back if that works to 4K resolution.

I've just updated my Big Sur 11.3.1 to DL 1.4 and all is working fine on my 3 x DL 2K setup.

I've not tested screen rotation because can't see such option in Preferences > Displays anymore? Attached are the only options I'm getting:

Has anyone installed the latest macOS Big Sur 11.4 update yet?

Ta,
David

Low res 4k is available but other than that no other HiDPI resolutions above 1920x1080.

100% BUMP

macOS 11.4 and DL 1.4 on M1 = rotation options gone.
why?

If DL 1.4 was suppose to improve rotation performance, I am going to assume that being able to rotate the display is a prerequisite.....
