the mouse slows down with two active monitors - HELP

Postby ginetto » Mon Dec 11, 2017 5:36 am

I have two randon HD 3850 which with only one active monitor working properly. When the second monitor is active, the second monitor is displayed correctly but the mouse sometimes slows and stops, then restarts and then returns to slow down.
