I have 2 monitors (1920 x 1080) connected to my Gigabyte Nvidia GTX 770 (GV-N770OC-2GD):
BenQ XL2430T (Primary)
BenQ E2420HD (Secondary)
I currently have my XL2430T (Primary) set to 120hz and connected by Dual Link DVI-D, my E2420HD (Secondary) set to 60hz and connected by Single Link DVI-D.
This is the first time I have had more than a single monitor so sorry if this is a stupid question.
I have noticed that if I have a game running on my secondary monitor (60hz) while I have anything else on my primary monitor (120hz), I get FPS drops for that game (Fluctuates between 40 and 60 FPS).
If I play the game on my primary monitor (120hz) while having anything else on my secondary monitor (60hz) there are no FPS drops.
I also get no FPS drops if I play a game on my secondary monitor if I lower my primary monitor from 120hz to 60hz and have both monitors running at 60hz, and I know that it seems stupid to be playing a game on the secondary monitor but I am still curious. I have monitored my CPU, RAM and GPU while these drops occur and they are far from maxed out so I am sure that this is not an issue with any of those.
From searching I have found that disabling Windows Aero (Win7 Home Premium 64 bit) 'fixes' this issue but as a result causes screen tearing, I really would prefer to leave Windows Aero enabled as I like the look of it.
Any help would be greatly appreciated.
