Lets say we have two screens with same resolution (720 x 1280) but different sizes and hence different ppi (pixel per inch):
720 x 1280 pixels, 4.8 inches (~306 ppi pixel density)
720 x 1280 pixels, 4.3 inches (~342 ppi pixel density)
Would this have any affect on the CPU or GPU processing (no matter how minor) ? If yes, which one of these two would use more CPU/GPU for display purposes?
IOW, would a screen with higher PPI (but same resolution) demand more processing power ?
