Mouse Lag on attached screen in macOS Sierra

[heitorbranquinho]

My magic mouse is very slow.

I use the OS High Sierra 10.13.6 and my macbook pro early 2011, but with SSD and 16MB Ram.

With a simple mouse at USB port it works in normal speed.

I`m using two monitors, the same model, Samsung T24C310, one by Display Port USB and the other one in the thunderbolt port.

Thanks for any help!
