Hi
i have few questions about this display.
1) G sync ?
2) is it good in gaming (im gonna pair it with the 1070) ?
3) How it looks on lower resolutions in gaming like 1080p is the upscaling so notable?
2) You'll probably need to turn the settings down a bit at 3k if you want 60 fps
3) That's probably a question of taste. 4k screens apparently scale down to 1080p reasonably well, but that might not be surprising given that 4k is 2x up and 2x across 1080p. 3k isn't and probably won't look as good. I haven't seen it in the flesh so can't give an opinion on whether it looks fine nevertheless. This review is of a defiance with a 1060 and 3k screen, it might offer some insight: http://www.bit-tech.net/hardware/laptops/2016/09/26/pcspecialist-defiance-iii-review/1
