I have upgraded from the 290X to MSI 980Ti using 368.81 driver version which I have two Asus 60Hz monitors (same model) both connected to the 980Ti via DisplayPort to HDMI (monitor) but when I enable the second monitor (Extend in Windows), I can see the stutter/lag in Windows when I minimise applications, typing in Microsoft Word and browsing online etc like it is in slow motion however when I switch back to (Computer only in Windows) single monitor, it goes back to normal with no stutter/lag. I have searched online and there is people with the same problem with the 980/780 so I'm wondering is there a fix?
