Most people think that at some point, higher resolution smartphone screens are always better. In fact, it is not, because the maximum pixel density that the human eye can distinguish does not exceed 300 ppi (the number of pixels per inch), and there is not much difference to the human eye beyond this value. At the beginning of this year, LG launched the first smartphone with QuadHD resolution, the LG G3, with a resolution of 2560×1440 pixels and an astonishing PPI of 535, which is much higher than all previous smartphones with a resolution of 1920×1080. few.
But can our eyes really tell the difference between the LG G3 and the Galaxy S5? The screen PPI of the G3 is much higher than the Galaxy S5's 431 ppi. In practice, though, there's hardly any difference in sharpness between the G3 and the Galaxy S5, which is why a company like Apple cares more about the brightness of the display than the resolution.
