Hello, i'm having an issue with this particular model. Before this i had my hands on an acer predator g5-793 which was awesome. The only downside to it it was it had terrible bleeding at the top corners. In rest the laptop was pure awesome but because of the bleed/glow i returned it and waited a time. That one had 75hz gsync and only had gtx 1060 , no intel , no optimus... which is great for a gaming laptop. My problem is with the nvidia not showing display tab in the nvidia control center as it is handled by the intel driver. How in the hell i enable g-sync or how do i know i have gsync enabled. Also it's my first device that has dead pixels... can't return it unfortunately, i have to get used to some dead pixels. But my main problem is that v-sync at 60 fps causes a diagonal line when i play games with v-sync on. If v-sync is off i have no problems , but if i'm gaming i don't want to go more than 60-70 fps cause the laptop cooling system transforms in an airplane... which sucks. So i used dxtory to limit my fps to 59 then to 70. If i limit to 60 fps it would cause a diagonal tearing that goes from upper left to lower right corner. My problem is , i don't know if my g-sync is on because there is no display tab to show me that. I used nvidia inspector to look on global settings but i guess i have to have better understanding of hex to know what values are on. I kind of regret a little that i bought this laptop , mainly because the cooling system is loud , it has some dead pixels , at 60fps i have screen tearing and optimus on gaming laptop COMPLETELY SUCKS.
