Something odd just started happening when plugging my GL702VS into my Samsung 4K monitor...it matches the screen resolution on the laptop itself. It's almost like it's backwards, so the panel is indeed a 4K panel on the laptop, not a 1080P panel. I am able to make a custom Nvidia resolution of 3840x2160@75Hz but it doesn't stick, when you hit OK it will go to that but when I go back to the resolution list it's missing. It flashes and shows up but then disappears.
Anyone else had this happen? If it is indeed 4K, as it appears (I made sure the virtual resolution was not on) I wouldn't mind using it for gaming, I game on a 4K TV and monitor and having a screen that small on the laptop it would look fantastic. Yes, it's a 1070 non-MaxQ so I do have to adjust some settings, but it's worth it.
