The Sony Xperia Z5 Plus is supposed to come out with a 4K Ultra HD screen

Rumors of 4K UHD displays for smartphones are something we’ve covered on numerous occasions here on and with good reason –the idea is deeply enticing to technology and display graphics fans as well as many consumers most likely.

While so far no rumors have ended up panning out with a live consumer market model, the technology itself is surely going to arrive and soon. This is why the latest news of Sony’s Xperia Z5 Plus emerging with a 4K display are no less plausible than have been other such speculations. Sony itself is a major innovator in the sphere of 4K display technology, particularly in its TVs and projectors, so if any major smartphone maker is likely to emerge with a 4K screen, Sony is a definite first rank contender.

In any case, the word circulating across the web is that Sony Mobile might certainly be one of the first smartphone makers in the world to release a phone with its own 4K display. The specific model rumored to be getting this awesome new pixel density to its display is none other than the upcoming Xperia Z5 Plus.

A 4K resolution on a screen this small would of course mean an absolutely sky-high pixel density and if 15 inch 4K laptops displays have so many pixels that you can’t see them no matter how hard you squint, then you can image what the PPI (Pixels Per Inch) of a 5 inch display with 3840 x 2160 resolution would be.

The main tidbit that makes us and other suspect the possibility of an imminent 4K display comes from a user-agent profile for all variants of the smartphone. If one looks closely, the profile data for the screen of the z5 Plus clearly shows a listing for a screen resolution of 2160 x 3840. Furthermore, the same profile data also claims that the phone will run on one of Qualcomm’s Snapdragon 810 MSM8944 chipsets. These chips, as we’ve covered before, are known to be powerful enough to handle the rendering needs of a 4K display.

The profile data however doesn’t make much mention of anything about the actual screen size we can expect on the Z5 but we can fairly safely assume a screen in the 5.5 inch range. This would mean a PPI of about 801!

Most users honestly won’t be able to tell the difference between a 4K resolution and a Full HD 1080p resolution on such a tiny screen. Thus unless the phone can manage to stay within a reasonable price range despite its immense screen, or offer a pile of extra powerhouse specs to justify a higher price, many users may not even bother paying more for a 4K display that they can’t visually distinguish in a side by side comparison with 1080p HD.

We’ll have to wait and see if the 4K smartphone screen rumors finally pan out.

    so what’s the point of resolution that dense on a phone? i keep reading articles that i won’t be able to see a noticeable difference in the 55″ 4K tv that i’m looking to buy from the distance of my sofa and 1080p. how can anyone possibly tell the difference in 326ppi (my iPhone 6) and (good lord) 881ppi of this rumored Sony?

    can’t wait to see what that does to battery life, too.

      As far as the eyes go, you’re absolutely right. You physically cannot tell the difference with these extreme levels of pixel density. However, buyers love the latest specs and if 4K is possible without being too costly in dollars or battery life, then it will get built into such small screens.

    It s supposed to be the related to the Xperia Z5 and Z5 Compact, both leaked with a Power button with oval shape and fingerprint scanner on the sides. The leak comes from a Sony Mobile slide, that has appeared in the Asian media.
