How to fix mouse lag with Samsumg M8 Smart Monitor as an external monitor?

Hi apple,


I have a macbook air with macOS Ventura 13.2 software and an apple wireless mouse. I am trying to use my samsung monitor as an external display. But my mouse is lagging on the samsung external display monitor. The mouse speed is perfect on my macbook but it is quite slow on the external monitor. Do you have any suggestions on how I might fix that?


Thank you!

MacBook Air 13″, macOS 13.2

I have the same problem, but not on all monitors, the problem by myside:

  1. Perfect with no problem with my HP monitor e27u g5, I configured the resolution as 3840 x 2160 4K
  2. very lagging with my Samsung S32BM80, I configured the resolution as 1920 x 1080 which is the maximum supported resolution.
