LG's G3 has a lot of pixels. Like, a lot a lot. 534 of them per inch, if you want to get precise. How sharp is it? It's pretty damn sharp.
Yes, this actually is the G3's screen. Wowzers.
But is there any practical, even technical, reason to keep pushing on the pixel density front in smartphones? Or will QHD finally be our stopping point? Should 1080p have been? Do you care?
