The Sony Xperia Z5 Premium is essentially the same phone in every way except at the screen level, because in this model you’ll find the world’s first 4K Ultra HD smartphone screen.

To put that into perspective, that means you’ll find eight million pixels being powered in a 5.5 inch display, providing four times the resolution of Full HD and sharper imagery and text.

That’s a resolution and size that outdoes everything else out there, trouncing LG, Apple, and Samsung with more pixel perfect clarity than any other phone. As a comparison, Apple’s Retina resolution on the iPhone 6 comes in at 326 pixels per inch, while Samsung’s Galaxy S6 reveals 576 pixels per inch, which was previously the sharpest display on the planet.

Sony’s Ultra HD display on the 5.5 inch Z5 Premium shows 806 pixels per inch, beating all of them hands down.

Just to put that into perspective, the human eye is said to only be able to see around 300 pixels per inch, though LG has questioned this in the past with the suggestion that around 530 pixels per inch could be representative of fine art book printing.

We’re not quite sure if anyone will be able to see the clarity Sony’s screen is putting out, but John Featherstone says that you can see the difference in quality.

“You will be able to notice the difference,” he said this week to GadgetGuy. “[Regarding] the clarity of the image, you’ve really got to see it side-by-side. I didn’t think it was possible, but it really is.”

We can’t wait, and the good news is you won’t have to wait long, with Sony Mobile talking up October releases for the Z5 and Z5 Compact, while the Premium model will see local release some time in November.

Pricing isn’t yet known, though we have been told it should be close to where the current Z3 models were priced at for the first two, while we anticipate the Premium might go for a hundred or two hundred more.
