Why do people use 'need' when trying to justify their opinion? I mean people don't need a phone in the first place. The proper terminology would be want but people already know that they've lost that argument as some people will want a 4K display.

    Orch , 07 Sep 2015Nice language, such taste for good manners for people you d... moreI really dont care. If you have read any previous post of mine, I worked at Sony DE and I know what was allowed and what wasn't at the event. There is a reason why there was so many restrictions and why the release date is in Nov not Oct. not really a lack of supply of 4K screens as mentioned by some members....

    And the teardown was published on purpose to end this SD810 heat propaganda as it has become a real threat.

    It's still unpolished, a prototype, and Sony is too conservative when it comes to this phone particularly, you'll find out later but they're doing their best to make this device successful.

    Anyway I really doubt an Apple reviewer would take a front seat at that event

        Now for a 5-6" display to say that will be biiig difference between a fullhd and 4k or 8k or 100k for naked eye for all ages...is just trolling
        Under microscope is the real difference

          Before , people said :
          "No one needs a colored screen phone" ;
          "No one needs a Camera phone"
          "VGA resolution is the max that we could get"
          "who needs FULL HD in a phone"

          The rest is history.

          Maybe 20 years from now, this 4K resolution will be the "VGA" of the next generation.

          So stop being a hypocrite and just admire the innovations that these tech giants are doing.

Of course, it may be the case that 3D renderings are locked (at least by default) to 1080p and then upscaled to 2160p. For example: GFXbench curiously refers to the resolution of the Z5 Premium as being 1080p.

            Such a strategy would make sense in that 4K amounts to a lot of pixels for a mobile to push (though it is not out of the question for certain workloads).

Most people were not allowed to even touch the Z5 premium at the event... For those who were, they went through the OS quickly and played with the camera... And you're telling me that you threw a 5K video on that device ?

                    Sorry to say BUT i was at the event , and i tested the Z5 Premium.
                    I have at home imac with 5k and i run some 5k videos on the Z5 premium.
                    While on my imac i dont see with naked eye the difference between 4k videos and 5k, based on the imac display and the view distance, i never ever for 1 sec didnt saw any difference between the same 5k video on Z5 premium and iPhone 6 plus or Samsung Edge.
                    These things should be for laboratory and not for normal users bec you pay for something that you don't take advantage

                            I see things ALLLLL the time on IPS panels in the sunlight. This would really only be a problem on mid and low end phones with cheap displays.

                                4K is obviously gr8,
                                If a handheld device is capable of 4K, our eye is sharply tuned into perfect vision, as you know that the pixel density make it closer to reality, & let the competition goes to give the best in consumer hands..
                                Saw some comments blaming 4K, then why people running behind octacore, 10 core & 12 core?
                                We need the best in speed , Quality, Display ..

                                      In my opinion,it is completely useful for VR gadgets,and because of this fabulous screen resolution the programmers can design their apps in more reality way,Sony can see the future and I'm so grateful for that.
