No retina mode
 

Before the big sur update the monitor at least gave me two HiDPI choices 4k and 2k? Now I no longer get the 2k as a HiDpi choice. I never received any of the other HiDpi settings that my other monitors which are the exact same but plugged in via mini-display get which are many HiDPi settings.

I have attached the logs from my computer. This is becoming unbearable. 4k native resolution is not really usable.

+1 to this, after running through Fujitsu PR09 dock scaled options are very limited

I am using a dell dock. I wonder if it is the docking station.

If you click to select the 'Default for display' option radio button next to the 'Resolution' category does that list all of the display's resolutions, and if so does choosing one of them help?

It's the same with Dell D6000 dock

Does this help? --> https://support.displaylink.com/know...-not-available

No it does not, running anything through PR09 or D6000 doesn't support Retina/HiRes modes beyond default for display which runs full 4K which in office scenario is as stated by OP useless.

Sorry that was not helpful...

According to this post --> https://www.displaylink.org/forum/sh...46&postcount=4 the next release of the macOS DisplayLink Manager App version 1.3 will be released in the near future. Maybe that will help in this case?

Bought a dedicated usb to DisplayPort same issue
 

I went and bought a new usb to display port and I have the same issue. I don't have any other hi resolution choices besides 4k. This was not an issue with the old driver. I went back and installed it and I got a hi res 2k option.
