So I know that 4K (2160p) is the equivalent of having the amount of pixels of a 1080p display squared. Wouldn't this mean that down-scaling would work perfectly as 4 pixels should display the equivalent of 1 pixel when down-scaled? Using nVidia's presets in their control panel it still seems as if they do not scale 4:1 when you change resolution, as there still seems to be a bit of a blur. I am unsure on how to go about changing this manually so please help me 
. Thank you in advance.
