The smartphone Meizu MX4G will, most likely, offer it's users one of the most detailed 5,5 screen out there with a resolution of 2560х1536 pixels. It has an incredible pixel density, which even surpasses the Retina display of the iPad. In short, a pixel density of 540 ppi.
There is a catch here - the human eye can recognize as far as 320 ppi, meaning that, most likely, a pixel density of 540 ppi is way beyond of our reach.
Another issue to note is that those many pixels require a lot of GPU processing power especially when it comes to gaming.
Still, this is a great marketing strategy and we will wait eagerly to see what the final product will look like.
