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 !!

I would also like to report lag input on the computer. I am using a MAC with two external Samsumg gaming monitors.

Latest drivers don't seem to have fixed this problem! Please fix the input lag on 4k screens on MB bigsur!

same here, macbok pro 16 inch, trying to connect 3 4k displays scaled to 2500 lags. If plugged directly in via usb-c it works fine

Same here, dell d6000, 3 displays, 1080p, same setup worked fine before big sur. I tried to upgrade to displaylink v1.3 and it got even worse

I have exactly the same issues. What an absolute load of rubbish. The Mac is more than capable but the display link monitors are just too laggy. SORT IT OUT ! So annoyed!

Same here. Unacceptable performance.

For those having slowness issues, I've noticed that if I set the resolution to 'native' and not scaled, that the lagginess goes away. It only seems to have laggy issues if I try to scale the screen to make all the text larger.
I've only had this issue since the recent mac upgrades.

Same issue. Just spent $200+ on two hubs that provide dual 4K @ 60Hz output. At that price this performance is completely unacceptable. This issue has been open since October. What's going on, DisplayLink? If your engineers are incapable, please contact me and I will provide you my contractor fees.

Same!!! 4k 60hz on displaylink is much worse and slower than original 4k 30hz, cannot be used at all...feel like I wasted my money on Dell D6000...

Same on Macbook Pro 16 with Big Sur 11.2.2 (20D80). Displaylink on Dell D6000 is unusable with 4k screen. Please fix this :(

I also have this issue with my 5k display that I have hooked into the Dell D6000 dock. Really hoping this issue can be addressed because having the lag is making using this display on my m1 mac mini really uncomfortable.

Works for me with the legacy driver 5.2.5 on a MacBook Pro 2017 with Catalina 10.15.7. I previously had the latest DisplayLink Manager installed, which caused a huge input lag. Also clamshell mode was not working, so i switched back to the old driver. I am using an i-tec USB 3.0/USB-C Docking Station 2x4K 85W and two external 4K displays (Samsung U28E590D) in 2560x1440 res.

Hi! Same issue here.
Macbook Air M1 with 2x 4k 27" monitors; one over DisplayLink via Targus dock, using DisplayLink Manager 1.2.0 (Build 55.125).
Issues:
1. Can't set 2560x1440 HiDpi on DisplayLink monitor (only 2560x1440 (low resolution) shows up.
2. Still suffering the rotation bug that makes everything freeze/hang if the monitor over displaylink is rotated (direct connection monitor not affected).
Mostly concerned with #1, as I can run the vertical monitor directly from the M1 (but the second display still needs to be over the displaylink dock/hub).

I have MBP with displaylink. Just did a fresh install of Big Sur on a new SSD. Keyboard input is very laggy. Sometimes works fine. Sometimes it's awful. I had been using displaylink with same USB3 unit and same MBP for years with other versions of MacOS and it was just fine. This is not usable. Going to downgrade to Catalina.

I have 2x Samsung 28" 4K Monitors via Displayport cables on my Dell D6000 that is connected to my 2017 15-inch Macbook Pro . I experience a huge lag when working on the monitors but not when working just on the macbook screen. I have tried both display link managers 1.1 and 1.2. and I have this problem with both of them. With the last Display Link Drivers 5.2.5 and 5.2.4. the lag is gone BUT I can no longer use the scaled options from mac os (4 pictures to choose from that say "looks like 2560x1440") which make also 2560x1440 seem sharp. I just have a windows like menu with more options, especially if you open it with "alt" pressed BUT 2560x1440 is marked as (low resolution). I didn't have this problem with the display link managers BUT I prefer it to the unworkable lag problem!
