Much has been made of the Sony Xperia Z5 Premium’s 4K resolution display. Sony Mobile garnered many headlines on being the first smartphone manufacturer to release a phone with 4K resolution (2160 x 3840 pixels) and 806 PPI pixel density. But since then, some have questioned the need for such a resolution on a 5.5-inch screen and whether the human eye can actually notice the difference.
We wanted to put the matter to rest by asking actual owners what they have experienced on a day-to-day basis. If you own the Xperia Z5 Premium, can you notice the 4K difference when viewing higher resolution images or videos? If you can, how big is the difference to your eyes? Or, do you think 4K is just a gimmick with little ‘wow’ effect? We’d love to hear your comments below.
