5 reasons why the Xperia Z5 Premium's 4K resolution screen makes perfect sense

5 reasons why the Xperia Z5 Premium's 4K resolution screen makes perfect sense
So, today the world saw its first 4K smartphone, courtesy of Sony and its illustrious Xperia Z5 Premium! Kazuo Hirai threw quite the bomb there, eh? Are you excited? Heck, we're thrilled, but we're also aware that many of you are scratching your heads, wondering why would anybody need this many pixels on their screens! After all, you are right to be asking this question, as before the Z5 Premium came around, Quad-HD smartphones did a great job at convincing us that extra fidelity beyond 1080p resolution is pretty great, but totally inessential to a smartphone screen's quality. "Overkill", in other words.

Thus, we felt compelled to share 5 very good reasons why a 4K resolution smartphone screen does make perfect sense, right here, and right now. We're looking forward to discuss this stuff with you all, so please, chime in with your fresh comments below!

The first point is the only point necessary. Technology always goes on, and we always want more, so if we can have it then why not It's the first time Sony has sparked my attention with this Premium

It is a good thing they offered the option of FHD and 4K. So nobody can complain about FHD is too little or 4K is too much.

So that whole idea about previous 4k article poll can be scrapped ?

I will give you the world if you can cook steak using the Z3. The heat is really for you. Because you will suffer in hell. Bastard

You sir are not being honest! I've had the Z3 since it was released day1 and it heats casually just as much as any other phone. When I keep recording 4k with it it heats faster of course and get the massage that recording 4k will stop if it heats too much, and even when I push it till it stops recording the heat is not beyond an average that can be achieved playing a heavy video game for too long. I previously owned a galaxy S5 and that used to heat more than my Z3.

I remember when everyone considered 2k a gimmick and usless. Well here we are. I enjoy higher resolution.

"bringing it before the top dogs, before Apple, Samsung, LG" I wouldn't expect Apple to be bringing any new screen technology before Samsung .LG etc. A new soc maybe.

Wait...isn't this the same OEM who said QHD is pointless in smartphone screen...and fans where like 1080p is the best fit for smartphones...

Yeah that is why there is a Full HD & even 720p version for anyone who don't need 4K display. But for Sony haters who bash Sony for using Full HD display when every other major OEMs put QHD display on their phones, now they can enjoy the sharpest display on a smartphone from Sony.

This display won't feel any more shap than a QHD. Infact it won't feel much sharper than a FHD.

But pixel noise due to use of subpixels, will be less visible. And that can be seen on QHD panels, even from normal viewing distances. I also hope they managed to shrink the distance between the pixels. At some point we might reach a level where a white background actually looks like its a static white background, completely coloured. At least with QHD screens, and large UHD screens, you still have noise and pixel distance, and you can even tell on moving pictures even when the background is not in a complete colour. It's not all a matter if you can see pixels or jagged edges.

I'm almost wiling to bet that latter statement isn't true. I'm likely to get the premium to replace my oneplus one and I'll let you know!

Lol... it all depends on how good your eyes & the distance when you holding it. But when you using it with the Google Cardboard you'll see the benefit of 4K display.

It still kinda is, however, fans spoke and they responded. Nothing wrong in that.

Yeah, they did say that QHD is pointless and this is the reason they released UHD screen, not Qhd screen.

Could be... there isnt much of QHD material out there, so they would have to scale pretty much every bit of material. Whereas 4K is an actual standard.

Why do u need so many pixels on your camera? Social media go upto 2mp or 5mp, and the screens are either 2mp (1080p) or 8mp (4k)

live isnt all about socmed.. maybe they want to keep nice full resolution pic for personal/family reminiscence, or to edit it later, or to get nice detail when u zoom and crop it..

In the other article, you Phonearena who said 2K screen is waste of resources because 2k 4k content is not available. Now you say reversely !! really ? what a joke

21. SonyOwner unregistered

The technology is here. Thanks to Sony. The are the real innovative company.

so basically the only reason for making a 4k mobile screen is because they can?

A first for Sony phone to really turn me on...'z5 premium ' ..I so want it to produce excellent performance so that it gives the "boastful " Samsung a hard cracking mind thoughts and give us what "many " expected in their next line of flagships esp note 6

Phonearena just released an article a couple days ago how 4k display phones weren't needed...

What happened to that "we don't need 4k on phones" article?

30. StanleyG88

They are basically saying that if makes sense to do it because you can. By that same logic, I'm expecting in a year or two to have smartphones certified to 660 feet underwater indefinitely and withstand 200Gs without damage. My watch can do that now, why not my phone?
