I have high CPU usage (usually between 50% and 150% as reported by Activity Monitor) on the DisplayLinkUserAgent process.
This is with 2 screens, one of them in portrait mode. I've tried DisplayLink Manager 1.4.0 and 1.5.0 Beta 1.I'm on a MacBook Pro (15-inch, 2017, 3.1 GHz Quad-Core Intel Core i7) with macOS 11.5.2

FIXED!
Resolved with DisplayLink Manager Graphics Connectivity 1.4MacOS Big Sur 11.5.2
I just updated DisplayLink from 1.2 to 1.4 and the slowness on my rotated monitor is gone. It behaves now the same as my other non-rotated monitor -

Just got this response (mere hours after contacting them):
Hello,
Thank you for contacting our support.
The best way to get our feedback is to contact us directly like you did right now.
As for the rotation support, we are currently working on improvements on MacOS for rotated screens so it is for sure visible on our radar and we are planning to help our users with it in the future.
Unfortunately, I cannot say when it will be ready as we do not have an ETA for that but I can assure you that our engineers are working on it.
Kind regards,
Jakub -

February 2021 and I still have problem with the rotated 90 degrees monitor to lag

Exactly the same problem for me on Mac (Big Sur, DisplayLink Manager 1.3.0) - one of my screens is rotated 90 degrees, and it has a very laggy / slow performance when moving the mouse pointer over it, and especially when dragging / resizing windows and switching between desktops.
It's actually pretty unbearable / unworkable. I'm thinking of switching back to just using direct connection to my laptop..

Seems like this falls very much in the too hard basket considering the number of people posting and profound silence from Display Link.....

I tried Dell D6000 with 2020 M1 Mac Mini and 1 4K display rotated to 270 (and two other 4K displays at 0 degrees directly connected to the Mac) - it just doesn’t work. The rotation simply doesn’t take - the only setting that works is 0 degrees. Just so I’m being clear all software (OS, drivers etc) are updated.

For me, the rotated display works properly except that the image is rendered very slowly, i.e. mouse positioning has a significant lag. It becomes even worse when hovering over animated UI elements (for example hyperlinks in browser).

On M1 BBP13" running OSX11.1 and latest DL driver with Dell D6000 + 2xDell P2419H (1 via HDMI 1 via display)screens the rotation just doesn't work. It crashes continuously and the image does not render correctly.

Rotation is not working with Display Link Manager 1.2 and Big Sur with 4k monitor rotated 90deg. The monitor just freezes up until the rotation setting is reverted.

just bought DisplayLink to start using on macOS Big Sur 11.0.1 using MacMini m1 16GB RAM with Dell 27" 4k monitor and DisplayLink does NOT support rotation - the apple system preferences shows the monitor as being rotated, but the imagery is very much still looking like landscape when screen is portrait making editing long word documents extremely painful.

Any updates on this? I have the same issue

René Sluiter commented
on the one hand I glad I found this thread, meaning I just rotate my screen back to normal and the lag is gone. on the other hand, how can this be an issue. if landscape mode works without problems, then why is portrait mode so buggy/laggy? Please fix guys. I got an old asus MB168B+ here and it's unworkable in portait mode and big sur.
Rotation is there though. -

Would love for this to work in DisplayLink Manager 1.1 for Mac. Rotation would be great.
