M4 Macbook pro

My issues are mainly with Chrome and Slack: the display is super-laggy when scrolling and dragging and dropping, and the pointer sometimes skips around. Don't have issues with the primary display with the same pointer, so it's not a mouse issue. For some reason, I don't have a similar issue in Apple Mail.

I'll go ahead and send my details to that same email address listed above.

According to the information provided by Plugable for the UGA-4KDP adapters --> https://plugable.com/products/uga-4kdp the adapters support a maximum resolution of 3840x2160 at a 30Hz refresh rate. This is half of the more typical 60Hz.

If you are running your displays at 3480x2160 at 30Hz, it could result in behavior similar to what you describe.

It appears that lower resolutions support a 60Hz refresh rate. If you lower the resolution of the displays connected to the adapters to say, 1920x1080, does that change the behavior?

Unfortunately I am already running the displays at 1920x1080 at 60Hz. Haven't come up with a solution yet, bc of the mouse jumping I'm constantly clicking/dragging the wrong places.

Understood. If you have not done so already, I would suggest contacting Plugable directly for assistance --> https://plugable.com/pages/support

I also am experiencing this same issue of input lag with DisplayLink on the MacBook Pro M4 Pro laptops.

Its most notable when typing for me. I have been able to reproduce this with multiple different DisplayLink docking stations from various vendors, running the DL6950 IC. for me the issue is most consistent when running on 3440x1440 ultrawide monitors regardless of refresh rate.

I have a 2 different triple display docks that both support 2x monitors on DL6950 and 1x on MST through the dock. the monitor connected to the MST port does not experience any input lag, but when you move an application to one of the DL connected monitors, I can see the input lag when typing.

its only with the new M4 Pro laptops, that I am seeing this issue on.

It looks like the problem we see on our side has been solved. The fix will be in DisplayLink Manager 1.12.0, which will be released soon.
