I'm surprised at you Xlucine... truly.
bigger? it's not bigger... this is pixel density not size.
both 1080 and 1440 could be on the same physical sized screen, and the 1440 would have more pixels squeezed tighter together.
Moreover, if we DD assume all pixels were the same size and scaled up the images on each...
1440-1080 = 360 larger
360/1080*100 = 33.33% increase in pixels
33% isn't a "hair". I'd take 33% improvement in my car's fuel consumption. I'd take 33% improvement in my frame rates.
that Netflix image is v missleading
(and the official 2k is actually 1080x2048 but lets carry on)
this is closer to accurate
