By launching an iPhone 4 with Retina Display, Apple demonstrated that users want screens in their smartphones that display images as clear as possible, other manufacturers have understood this and since 2011 have started to launch mobile terminals with as many pixels as possible per inch. Although at the moment most smartphones have at least 300 ppi, smart phones with 1080p, 1920 x 1080 resolution are already starting to appear on the market, their manufacturers proudly presenting the benefits of such a resolution on a diagonal of at least 5 inches.
Although many wish to have such a screen in their pocket, the CEO of DisplayMate says that between a smartphone with a 720p resolution screen and another with a 1080p resolution, there will not be very big differences in normal use. He says that normal users will not notice big differences between the previously mentioned resolutions and only in the graphics generated on the computer will they be able to truly appreciate the quality of the screens. He says that most multimedia content will not be displayed extremely clearly on the screen and this is due to the way in which that content is made. It should also be taken into account that a large part of the content is scaled to be displayed at certain resolutions, and this scaling partially reduces its quality.
For some people, it is possible to tell the difference if we were to sit down and study a [1080p] display and a [720p] display, side-by-side. If you're really a fanatic and you study images, or you have some professional applications and you're really into displays, then it may make a visual difference for you. Even the tiniest image detail in a photograph is always spread over more than one pixel. The image detail is never perfectly aligned with the pixel structure of the display. Videos are even worse: not only are they fuzzy like photographs, but the pictures are constantly moving. Even if the images were sharp, the human brain couldn't zero in on content that's appearing for only a fraction of a second on such a small display. For ordinary viewing of videos, 1920×1080 is really not going to make a visual difference.
Basically, Raimond Soneira says that only in Android OS, games or various applications will we be able to appreciate the true quality of a 1080p screen, but the rest of the multimedia content might disappoint us, and this because of the way it is made. Now no one says that screens of this kind would not be useful in smartphones, but we cannot appreciate them at their true value due to the fact that our vision would not be good enough, but also due to the fact that little multimedia content it is made at a high enough resolution to run on them. If you have an iPad 3 tablet and surf the web, then you have surely understood that the internet is not currently ready for such resolutions.
I, for one, welcome the implementation of 1080p screens in smartphones, I hope that the world will receive them well, but at first I think there will be some problems with them.
