Continually increasing resolution displays in mobile devices is a trend that leads nowhere. Similarly, Sony claimed his time, but new information portal which reached XperiaBlog say something completely different – Xperia Z5 Plus is supposed to be equipped with a display with a resolution of 4K! But how much is this the truth?The list User Agent Profiles can find some information on the model, codenamed E6833 indicated that according to speculation could be marked Sony Xperia Z5 Plus (the name is of course not certain; it may well be that the Xperia Ultra). In addition to the confirmation of existing information as to the application in the future flagowcach from Sony Snapdragon 810 (MSM8994), you can also be observed there used screen resolution – 3840 x 2160 (4K) and this is the stunning. While we do not have any information as to the diagonal of the screen, but if it is assumed that it will be 5.5 inches, it will have to deal with the density pixels at 801 PPI, which on one hand is a great value, but on the other – completely unnecessary in smartphones. 2,015 years brought us a large range of devices with displays with a resolution of 2K (2560×1440), which is already too high value for smartphones or phabletów. No one can convince me that he could see individual pixels even 6 inches with resolution ,, only '' Full HD (1920×1080) and so no one will persuade me that he sees tremendous difference in detail between the panels and Full HD 2K. Sony also said his time that such a high resolution as 1440p on a relatively small screens of smartphones brings no benefits, so it's hard for me to believe that the Japanese have gone even one step further and presented any smartphone with 4K resolution display first. I think they have found a wonderful way to guarantee that a real improvement in image quality, but it also hard for me to believe. I hope that Sony will go to their senses, and all this information did not prove to be true – but that we learn in the fall. Besides, if any of you imagine Snapdragon 810 in conjunction with the display of such a huge resolution?
