Lag and freezing issues with M4 MacBook + dock Dell D6000

guilherm · 11-15-2025, 10:52 AM

Hi everyone,

I’m having a really frustrating issue with my DisplayLink setup and I’m hoping someone here has experienced the same thing or found a workaround.

I’m using a MacBook M4 connected to a Dell D6000.

Whenever I try to use the MacBook touchpad to scroll a page on the external monitor, the action becomes extremely laggy — it almost freezes for a second, like the system can’t keep up.

The mouse scroll wheel works perfectly, so the problem only happens when using the built-in touchpad.

Other times, the external monitor completely freezes, and I need to disconnect and reconnect the dock to get it working again.

Has anyone else seen this random lag/freezing with DisplayLink on M4 Macs? Any tips or settings I should check?

Hi guilherm,

Sorry to hear about this problem.
What is your monitor brand, model, screen resolution and refresh rate?
On top of that, are you on the latest DisplayLink Manager version?

Szymon

Thanks for a reply.
It appears to be an issue we are chasing, no resolution yet.
Based on investigation so far we identified it only happens when a monitor refresh rate is high. Would you be able to gradually decrease refresh rate and test if there is any improvement?

If it stops reproducing, it is not the final solution, however it would confirm we are discussing the same problem.

Hi Szymon,

I gradually decreased and refresh rate and noticed an improvement, yes. It still has some lag using 50hz. However, it is much better than before.

Please let me know when you have a permanent solution for this error or if you need me to test anything else.

Regards,
Guilherme

Hello,
I have this same issue on an M4 Macbook as well; this is the only thread on the internet I can find regarding this problem.

Is there any traction on a fix for this?
Best,

Hi Yujalik,

Do you confirm that your monitor refresh rate is set above 200Hz then you experience an intermittent freezes while working below 200Hz it never happens?
