Fix drivers about screen lag when using external 4K monitor (macOS Catalina)
Please fix DisplayLink Drivers as using an external 4K monitor (Samsung S32R750) with Targus DV4K with latest drivers (5.2.5) on macOS Catalina (10.15.6 on MacBook Pro 16" 2020) plugged through Apple USB-C cable (40 Gbits) is making everything "laggy" on the external 4K (mouse, space change, video playing, etc.).
Everything has been tested (cables check and changes, switching HDMI or DisplayPort, using original Targus single USB-C cable or using Apple USB-C cable, etc.) to see this issue it is ONLY and DIRECTLY linked to DisplayLink Drivers on MacOS.
No issues when using a simple USB-C adapter with 4K HDMI (instead of my Targus DV4K Dock) : this is crazy as most of these adaptors are under $100 or even $50 compared to my Targus DV4K which is more than $300 !!

Is there a fix for this? Our company bought hundreds of these things, and they're completely unusable at the moment.

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

Just got a DisplayLink this week and I'm having the same problem here. External monitors work fine when plugged directly into my Macbook Pro (either via DisplayPort or HDMI cables), but are super laggy (and not crisp resolution, despite what stats say) when I run them through the DisplayLink.
Glad to hear I'm not alone, but I'm considering just returning this DisplayLink, as it's unusable in its current state.

This is a HUGE issue, its basically unusable. Using big sur with 2 external 4k monitors. Makes it seem like my mac is crawling to get things done but its just on the external monitors. Go back to the macbook screen and theres no lag.

Same issue. MacMini with 16G, dual 4K monitors, and the whole thing runs slow. Removing the DisplayLink and using only a single monitor plugged directly into the Mini and the whole system is quick and responsive with the same apps running but without the DisplayLink driver.
Also, watching top I see that DisplayLink is sucking up huge amounts of CPU time.

I seem to be having the same issue. 3 external monitors, Big Sur, and display link. When using applications like photoshop and bridge my system becomes unresponsive and hangs. It doesn't seem to exhibit this behavior when using my laptop on another monitor (no displaylink device). I don't recall this being an issue on previous versions of macos.

Any updates from DisplayLink on this, I just bought equipment worth $350, macOS big sur is laggy as well, however, when I boot the same machine to Windows, no lag whatsoever. Please fix this DisplayLink team

My Targus DOCK180 is just unusable. This needs to be fixed! As of now, this thing is a brick. I can't suffer through my mouse constantly hanging.

Same here, the display link software is super trash when trying to link 2 4K monitors to my QGeeM docking station.

Agree with this! Running two external monitors and since upgrading to Catalina 10.15.7 it's become SOOOO laggy!

Same here! Only laggy when I run display link. Running on latest Catalina 10.15.7 connected to 2 monitors through TOTU docking station. My HDMI asus monitor runs smooth without display link, but in order to use the 2nd monitor Samsung ue590 4K I need to be running display link. When running display link the samsung monitor works but its laggy. Also tested cables but nope, its only when running display link.

Second this. The mouse was fine before I upgraded to Catalina (ninja upgrade or I clicked the wrong thing after putting it off for months) and now the mouse cursor lag is actually insane. Almost unusable. I am using the DisplayLink HDMI to USB adapter.

Same issue here. I have dual Samsung 4k curved monitors...laggy as hell when switching between windows or moving the mouse within screens. Plugged in my old WavLink Thunderbolt doc and it's smooth. I have a macbook pro running Catalina 10.15.7. Got this doc because of the 100w of power...but it should perform better than the 60w WavLink i would think.
