Xperia Z5 Premium may have a 1080p interface, render only media in 4K

Xperia Z5 Premium may have a 1080p interface, render only media in 4K
There are already a few forum threads, dedicated to the notion that the Xperia Z5 Premium, Sony's (and the world's) first 4K phone, won't always run the native screen resolution, especially when it comes to the Android interface. To quote one posting: ""[The] Android system runs with 1080p, only the pre-installed video and photo apps could drive the display with 4K. Apparently proprietary drivers are used [where] the "normal" app developers do not have access. So even with the screen capture or other apps [that] see the resolution, it will only show FullHD."

We can attest to that claim, as when we took screenshots from the Z5 Premium at the IFA expo, those were later shown to be Full HD images, not 4K ones. In a nutshell, it seems that you can view 4K media like pictures and videos in Sony's native gallery and player in its full glory, perhaps even set 4K wallpapers, but when it comes to the Xperia UI, it hasn't been redrawn by Sony, or upscaled further than 1080p. Some argue that this actually makes sense, as rendering a 4K interface around would place unnecessary strain on the graphics subsystem, leading to Snapdragon 810 performance slowdowns, and a battery life hit. 

These can be easily avoided by enabling 4K only where it matters most - in the camera/gallery, and during video playback and upscaling. What do you think, will you be satisfied with this eventual Sony approach to the world's first phone with a 4K display?

If there was a switch for my S6 to run in 1080p mode I'm down with that. Faster performance and better battery life. Just make it user controllable.

I hope an update come along and let more apps have the ability to works on 4K. I mean if I am someone who would buy Z5 premium ,then I would expect that the wallpaper with its icons can be seen on 4K (except icons on Play store are only QHD right now) Also I would probably want to see 4K videos from Youtube (if available) . What if I want to see a photo or a video on another app, that is not fair to see it on Z5 Premium. Because of all of that I believe that QHD is better than 4K ( until 4K can be used on more apps or always like QHD right now)

I'd like it more if they make it an "option" and you choose where to see 4k, where to see QHD and where to see 1080p rendered screen because if they do it on their own, you need to find a way to tell it, you are using a VR app and you need all the pixels you can have

I think this the same story with 2K games,videos,apps etc... Except YouTube going to run at native Android resulotion 1080P or less and only apps that support 4K like 4K videos and photos.

Its not... 2k on Note 4, S6 etc. Runs UI at native resolution and games are scaled to 2k also.

How are they doing this? are they simply adjusting DPI and resolution for certain tasks?? seems like a waste.

Seems pointless to me. Paying for a 4K display only to have it run at 1080p most of the time. No thanks!

Good move. I want the premium even more now...

This is a great move. It would be even better if there was an option in Stamina to (de)activate 4K in general.

The images and videos have the least visible difference between resolutions. The two places where that screen resolution will be useful will be Web browsing and reading, and the display is rendered at 1080p there, which is a shame as 1080p is not that good on a 5.5" display. Also, the panel will still consume more power compared to a 1080p display as it still has to light more pixels, no matter the resolution it handles. The only place battery will be saved is on the processing side. I don't get it. This is the most useless device ever. I'd go for the regular Z5 over this any day. And guess what, in 90% of the cases. Z5 will be actually sharper than Z5 premium.

I think it's a great move. I do wish 3rd party apps have access to this driver. I want clear texts when reading.

it will run 4k only when needed. i saw in gsm arena and we cant say its 1080p at normal time because its pixels r differ from 1080p pixels. they r using different pixel technology though.

Great move by Sony. This would give much more battery and performance surely. Sony getting better and better..

So it basically means I cannot view a Web page on chrome in 4k?

The only thing you can view 4K is videos and photos from sony specific two apps and thats about it. Even the wallpapers and everything else runs at 1080p

That's kind of counter productive ain't it. What good is having a 4k display if it can't be used for Web browsing which demands all the pixels it can get..

But your beloved iPhone 6plus runs at 1080p without the capability to play 4k content like the Z5 premium and you're cool with that! Yet you feel the need to trash talk a device that boast a feature the future iPhone 10s probably won't have. Besides the battery life of the Z3 runs circles around the iPhone 6 plus and Sony is king when it comes to delivering the singular most requested feature of today's smartphone - battery life! You're shamelessly hilarious my friend.

This is good actually, now if someone could just hack into it and we can manually change resolutions anytime we want that would be amazing :)

Even better. The user will get advantage of the 3430 mah battery with this resolution.

Nope it will mean nothing what mode the screen is in it will always do max battery damage, it will just not do big time damage to the sd810, but battery is going. To be crap

I like this idea. Later on I'm sure the 4k capabilities of the screen will be utilized by more apps and functions that will showcase it better.

What a piece of crap from a cheating company. This blatant lie makes me want to see this loser company go bankrupt pretty soon.

What did Sony ever do to you. Yet based on many of your other posts I think you just hate anything Japanese!

Yes, just try your best to defend your beloved company even if it lies to you.

Hey buddy, your beloved Samsung? They also lied with throttling and benchmarks results before. Companies are no saints so don't single out Sony from doing marketing deception. Everybody lies including you.
