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 !!

Same Issue here - is there any fix in the pipeline ? This renders everything obsolete
Is that a problem using just HDMI - is it fixed via DP ?

I have returned my expensive Startech dock for a refund as it is unusable and would operate purely as a paperweight - due to this atrocious bug.
After reviewing the history on this it is evident that this bug has been there for years and there is virtually zero chance of the vendor acknowledging the fault or resolving it. I fully expect that it is an intractable issue as it results from their fundamental solution design, which hogs the CPU and completely ignores the GPUs ... which are the components designed to do this job!
Bought 2 x these startech adapters and have now been using them successfully
... They do the job properly and your CPU is calm in their presence!

I am suffering from this defect, after purchasing a very expensive Startech Dock (https://www.startech.com/en-us/universal-laptop-docking-stations/dk31c3hdpd)
Connecting my MacBook Pro from USB-C to DisplayPort on my monitors provides great performance... So why, when using the DisplayLinkManager software and dock, does the performance crumble so that the system is inoperable, with unusable lag for the monitor display and operating mouse? Why does the CPU go wild on this process and cause the whole computer to grind to a halt?
Please can someone there provide some progress on what is being done to resolve this hugely serious bug?

It’s a joke that this would be a “suggestion”… please fix your product as it does not work properly.

I went from a pair of MSI displays to a Samsung Odyssey 49" and keep trying to use the Startech dock with Displaylink. The lag on windows opening/closing is painful. Startech even blames Displaylink for bad drivers. So here's my $300 dock and i have HDMI plugged into my laptop because of your terrible drivers. I feel like just tossing this dock and getting a laptop with Thunderbolt.

We are going to return all ZGO we bought for our company. No one want to use them, because of this lag. We have 2 4k monitors setup and this is so anoying. Using MBP with Monterey!

Have the same issue.
-MacBook pro 16 (2021) macOS Monterey (12.1)
-Asus ZenScreen MB165B

Experiencing the same issue. My configuration:
- MacBook Pro 16" (2019) macOS 12.4
- Dock Dell D6000
- 2x Dell P2323QE (res. 4K) connected via DP (premium cable) to Dell D6000
- DisplayLink last release available
Previusly the same configuration but with Full HD display works fine. But with 4k monitors it has so much lag. Its impossibile to work on it.
Switched to 2x usb-c (Mac) to HDMI (Monitors) and everything works fine.
Fix this issue please.
I have the same issue.. I have 2 4k monitor hooked up to Display link 4k. It has so much lag. Its very hard to watch and work on it.

Experiencing the same problems with one external display connected with a MPB (m1x - pro)

Experiencing the same issue. Macbook Pro M1 with 2 x P2721Q 4k 60hz via Dell D6000. CPU usage of DisplayLink goes up to 60+ percent once you have any movements on the screen...

Any time there is any video updates to my DisplayLink connected monitors @ 1080P (full screen video) the displaylink user agent service CPU consumption goes above 50% which correlates to the laggy mouse. MacOS Monterey / DisplayLink Manager 1.6. on a 15" 2018 MacBook Pro.

I have the same issue. DisplayLink need too much CPU power. Mouse is laggy and when I use DAW Software like Cubase or Reaper in combine with DisplayLink the performance is very bad. Please fix this, it's not a cheap dock.

I have the same issue! PLEASE FIX

Same issue with Startech.com Quad 4K DK31C4DPPD on 2019 MBP 16" running Monterey 12.0.1 and DisplayLink 1.5.0 Build 58.125. As others stated, needed to set to native resolution (no scaling) and 60Hz. Otherwise the lag and latency made the computer unusable.
But native resolution on a 4k monitor makes for really small text...
DisplayLink - PLEASE FIX!
same here. When can a fix/update be expected?
it seems this is around for over a year with no solution.

Same problem here, MacBookpro 2019. Targus DV4k(Dock190), connected with display port, extremely laggy when connected to my 4k monitor.
