I am forced to work on my laptop screen only (in an office where everyone works on 2 external 4K monitors). Because, when connecting with DisplayLink through the docking station on my MacBook Pro, 16 (2019) with 2,6 GHz 6-Core Intel Core i7, 16GB memory, the mouse lag is too much to work productively.
The docking station ( a Fujitsi docking hub) connects via USB-C, with 2 D-Port display connections from 2 x 27" Dell monitors.
I have the same mouse lag when connecting via HDMI to an external monitor on 4K or higher resolution. The external monitor refresh rate will not go to 60Hz. Which causes the problem of lag (internal display is at 60Hz and the external at 60Hz).
The only way I could solve the single external monitor problem, was to connect via D-Port (which then allows 60Hz).
Does anyone know of any possible solutions (since I am surraounded by Windows users with no issues like this)... yeah... it looks bad
I don't know why you're bothering with a DisplayLink dock with that MacBook Pro. It can drive up to four external monitors using first-class hardware video output!
MacBook Pro (16-inch, 2019) - Technical Specifications

Simultaneously supports full native resolution on the built-in display at millions of colors and:
- Up to two displays with 6016‑by‑3384 resolution at 60Hz at over a billion colors
- Up to four displays with 4096‑by‑2304 resolution at 60Hz at over a billion colors

It sounds like you have two 27" 4K monitors which take DisplayPort input using full-size DisplayPort connectors. If you were to
- Get two USB-C to DisplayPort adapter cables that are rated for 4K resolution
- Plug your two monitors directly into two of your 16" MBP's USB-C (Thunderbolt 3) ports using those cables
- Uninstall the DisplayLink software
that could help with the lag.
I'm guessing that you would like to continue to do single-cable docking. In that case, what you would want to do is to replace that Fujutsi docking hub with a proper Thunderbolt dock, one which supports attaching a couple of non-Thunderbolt monitors. You need Thunderbolt for the first link because Thunderbolt can carry a lot more data than plain USB-C can.
Other World Computing is one source to consider.

Skimming the descriptions, it appears that the "OWC 14-Port Thunderbolt Dock" would let you connect one display via a Mini DisplayPort to DisplayPort cable, and another via a USB-C to DisplayPort adapter cable (connected to the Thunderbolt daisy-chaining port, at the far end of the chain, away from the computer).
With the OWC 11-Port Thunderbolt and OWC Thunderbolt Go Docks – which have "Add 3 x Thunderbolt (USB-C)" as one of their features, I believe you would use two USB-C to DisplayPort adapter cables, plugged into two of the three downstream Thunderbolt (USB-C) ports."
There are Thunderbolt docks from other manufacturers (e.g., SonnetTech) that may have similar features.
Double-check with the manufacturer about the specific dock you are considering, but I think this general approach would be the way to go about it. Forget the Fujutsi docking hub – return it to the IT Department to give to someone who has a Windows PC – and get a proper Thunderbolt dock that will take advantage of the hardware video output on your 16" MBP.
