Does higher screen PPI has any affect on CPU/GPU usage ?

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 ?

a 720p resolution monitor is no different to a PC be it 13", 17", 42", etc., since its supplying raw data

a 1080p 17" laptop screen would be more demanding on a GPU then a 42" 720p LCD TV/monitor

at lower resolutions, the CPU tends to take up more work then similar work at higher resolutions where the GPU takes up more work.

if you want to know why that is, the answer is here where you asked the exact same question
