Improve DisplayLink performance on macOS BigSur (11.1)
I bought the "USB-C Universal Quad 4K (QV4K) Docking Station with 100W Power Delivery" ($500) and three 1440p displays ($1500) to find out my macbook-pro OS version (BigSur - 11.1) has unusable lag with DisplayLink... The mouse cursor is a jarring delay behind the inputs I give and swapping between application windows or workspaces has extreme tearing/stuttering.. looks like its running at about 5 FPS - this is on the recommended monitor resolution too
Really disappointing DisplayLink

Same thing happens to me on a vertical monitor setup, I posted details here: https://support.displaylink.com/forums/287786-displaylink-feature-suggestions/suggestions/42656011-dual-screen-setup-laggy-vertical-screen-displayl
Kind of disapointed for such a high price docking system.

I'm using the Dual 4K unit with a Macbook Pro 15/2018. I initially installed this on BigSur 11.0.1 and encountered only minor latency as described in this post with no other issues. The other night, my Mac auto-updated to BigSur 11.1, and I'm now encountering frequent erratic black screens (sometimes only one of my external displays); and, sometimes, after returning to the system and logging back in, neither external display will come up. My only recourse is to restart the DisplayLink Manager. Looking forward to an update for11.1 that will hopefully get my displays back under consistent control.
