My build is-
CPU: Intel Core i5-6600K @4.4Ghz
Graphics Card: EVGA 1070 SC
RAM: 16GB Corsair Vengeance @ 3200Mhz
OS: Windows 7 Home Premium
Main Monitor: 2K Dell Gaming S2716DGR (Has G-Sync and runs at 144hz)
Second Monitor: 4K Dell P2715Q (60hz)
I would like to mention that I also tried another monitor with the same problem.
Other monitor tested: 4K LG 27UD68 (60hz)
The Problem
When I have both monitors connected, there is some kind of mouse lag. For instance, when I drag a window on the second monitor in a circle, I can see there is a small but noticeable lag when moving my mouse. This problem goes away when I make the second monitor (4K) my main one using the Control Panel settings found under Screen Resolution. The problem also goes away when I unplug the main monitor (2K) and use only the 4K one. But obviously I want to use both. I can't keep the 4K monitor my main because games want to run on it while I want to game on the one with G-Sync and 144 refresh rate. I also don't want to lower the refresh rate to 60hz because then the games don't run at 144. I also messed around with the Nvidia Control Panel with little to no results.
Any help with this issue would be greatly appreciated. I tried looking on other forums and websites with no avail. Thank you!
