Smartphones with Quad HD (1440 x 2560) resolution displays

When we first heard that manufacturers might be making the transition to even pixel-denser displays than the flagship industry standard of 1080p, us and the community as a whole were skeptical of the value proposition. It seemed like manufacturers are sacrificing precious battery life for nothing more than bragging rights – after all, even people with perfect, 20/20 vision would have a hard time actually spotting a difference in clarity on such small panels. Regardless, the Android industry pressed on, and we currently have about a dozen of high-end, high-profile devices that offer as many pixels...

2014 xperias should have OIS if its a z1 upgrade then it will be "icing on the cake"
z1 does captures awesome pics , sony should work better on the software part to optimize the picture and video..

Afaik Android doesnt support greater than 480 ppi displays. For the Vivo, there won't be too much trouble since it's near to 480. However, if I am right about the 480 ppi thing, Oppo will be in a huge mess.
But, "I guess we'll find out, won't we."

Support for 480+ ppi(XXXHDPI) displays was added in either 4.3 or 4.4 if I'm remember correctly

I guess You Know Nothing, Jon AppleHateBoy Snow!
The limitation you're speaking about may be realted to the resolution but has nothing to do with the pixed density.
Resolution is how many pizels are in total, as the OS needs to handle all the real-estate of the display to draw the guy, apps, etc.
Density is just how good the engineers are at packing the above resolution into a smaller or bigger screen (phisical size that is). No OS cares how small a pixel is or big, you can make it (the pixel) bigg as brick it will not care.
You need also more memory on the graphic card to suport a bigger resolution; the biggest resolution supported by Android, confirmed by the devices that runs it at the moment, I believe is 1440p - look for smart TV running Android. Android Tablets are also comming.

you know that Optical Image Stabilization is no software, right?

Doesn't change the fact that Sony are short on both counts... :-)

What about Battery? Why there is no competion between manufacturers in Battery technology?
14. PootisMan (Posts: 230; Member since: 02 Aug 2013)
I don't mind the jump in resolution, but if battery is affected in a major way than I can certainly wait for battery tech to catch up.

The Note 4 with 1440p last longer than the Note with 1080p. In fact it last longer than any phone with QHD.

It's a smartphone!!! Not a girl. You aren't going to have sex with your smartphone. If looks are all you care about, then get an IPhone, cause that's what IPhone people care about is a status symbol.

Shmay I suggest something? If I shmay, what if I told you that iPhones are simply and mass subjectively elegant, classy, and good looking?
When I purchase a phone, I make my decision by how the phone looks and feels. You spend all of your time with your phone by looking at it while you're using it, while it is laying on your desk, sitting in your hand, or sitting in someone else's hand.
The same goes with a car, guitar, headphones, clothing, etc.
People want what they seem deemed fit to their taste. People want what appeals most to their eye. Am I saying this is the ONLY reason people want an iPhone? No. Many people (the vast majority of iPhone users) want an iPhone because of its clean, simple and attractive interface, its ease of use, and its elegance. Yes, "it just works". Other people want it because of a status symbol. But don't bolster your beliefs by thinking that is the only reason why people want an iPhone.
Why did I choose the Note 4? Because it is sexy. It is clean. It is classy.
Why do I want the M9? Because it is sexy. It is clean. It is classy.
Why do I feel this way, because it is taste. And that is where Apple goes above and beyond. Fashionable design and satisfaction to the general publics taste.
There are many reasons why people choose the smartphones they own today, many I did not list. Like budget, ecosystem, preference OS, etc. We can sit here all day and talk about this topic, but in the end, it will always come down to one factor.

In a way, there has been some competition with battery technology. LG introduced Lithium Polymer battery technology in their flagship device which is a step up from the Lithium Ion battery technology found in the competition.
71. chebner (Posts: 172; Member since: 17 Oct 2011)
LG has made advances in battery technology, and last year's G2 was one of the longest lasting for a flagship. This year? Enter the QHD screen plus additional power saving features and battery live still goes down.
All the R&D spent on the power saving features negated, and then some, by a screen that provides no visual improvements. Hmmm... seems like money well spent.
102. TechieXP1969 (Posts: 2998; Member since: 25 Sep 2013)
Yet the Note 4 with a QHD last longer tan the LG G3. Hmmmm!
80. StanleyG88 (Posts: 161; Member since: 15 Mar 2012)
Don't think LG "introduced" Li-Polymer in the LG Gx. I had Li-Polymer in my Droid Razr Maxx HD that was out over two years ago. Also, now have Li-Polymer in my Droid Turbo.

Yeah!Go to hell with your display resolutions.We want better quality displays.Manufacturers and people should learn difference between QUALITY and QUANTITY!F*** u dumb people.
Battery and quality are most important!
3. Bishop_99 (Posts: 74; Member since: 04 Dec 2013)
Yes! QHD, the correct name for this display!
Completely doubtful Apple would even venture here since their iPhones aren't even HD.
10. rodneyej1 (Posts: 3576; Member since: 06 Jul 2013)
Maybe not Apple, but Nokia/Microkia is very likely to join the QHD party sooner, than later.. With devices like the 1020, 929, and the 1520,, it's obvious that "Lumia" now understands how important it is to have the latest, and greatest hardware, which WP does have now.. I'd have to disagree with the article, not saying that a Lumia device will be first, but I believe well see QHD in 2014... WP8.1 either would already have support for QHD, or QHD would be a small GDR update away... So, I would put Microkia next on the list......

it will be great that watching videos on 5+ inches, 1440p display...and games also :D

Yeah man. That's what I was gonna write before I read yours. PC display sucks.
86. zachki17 (Posts: 255; Member since: 14 Sep 2014)
Just buy lg pc they are the only pc with full hd and Quad hd display with intel i7 and 8gb of ram .. Forget about apple mac and dell .

No, it's not outdated, this just shows how ridiculous this pixel density race has become. QHD monitor is just about perfect for gaming these days and consider that you keep the monitor usually 2+ ft from your face. With phones you have to account for users being closer to the actual screen, but anything over 1080 on a sub 6" device is silly in my opinion. I don't care for it, at all.
They're talking 4k screens for phones next year, I don't even want 4k on my desktop due to how expensive it is.
120. zachki17 (Posts: 255; Member since: 14 Sep 2014)
4K on a smartphone its immpossible pnly remors there is not processeour that can run 4k ,, after 3 years maybe ,, LG has talked about 3K on tablet maybe next year
6. csoulr666 (Posts: 98; Member since: 04 Nov 2013)
A small screen with such high resolutions seems to be more than a gimmick to me to be honest
Heck a 720p resolution is sufficient for a majority of people for displays upto 5.5 inches(the Galaxy note to has it and looks really good for normal usage)
This actually shows how manufacturers exploit "The more the merrier" thought hidden deep in the Human mind. QHD in a tablet is OK but in a five incher it would be very battery consuming plus people won't be able to tell it from a 1080p display unless they compare it side by side(after the initial placebo effect wears off that is)
8. Bishop_99 (Posts: 74; Member since: 04 Dec 2013)
If you play 1280x720 videos on a QHD phone or a 1080p or a 720p phone, then naturally you won't see a difference the display can't add more information to the video. But once you play a 2.5K or 4K video on these different phones, the visual difference will be very apparent.
For those people that feel that 720p is "good enough," this is not for them as the visual experience is not their priority and they truly don't look for it. For those people which main focus is the visual experience, the 2560x1440 displays will offer true benefits as we are always looking at the best visual experience possible, instead of it being just as another feature of the phone.
53. csoulr666 (Posts: 98; Member since: 04 Nov 2013)
A 720p screen is "good enough" if tweaked properly, take the iPhone 5..........It isn't even 720p but it's display is still praised and put against 1080p ones
55. Bishop_99 (Posts: 74; Member since: 04 Dec 2013)
It's "good enough" for those people that don't put the display as a priority. The iPhone's display doesn't look bad, but it looks noticeable softer when you put it up against 1080p screens. The fact that it isn't an HD screen shows.
113. zachki17 (Posts: 255; Member since: 14 Sep 2014)
Apple Display made By LG that s why there looking Good
And iphone 5s its to smalll smaller mean kore pixel
70. chebner (Posts: 172; Member since: 17 Oct 2011)
Bishop, you hit the nail on the head... "naturally you won't see a difference the display can't add more information to the video". But this is also an argument supporting why QHD screens make absolutely no sense. Resolution scaling is better than ever these days, but it's still not perfect. Whether scaling up or scaling down, there will always be scaling artifacts that will soften the image.
When watching videos the only way a QHD display will display all the detail it is capable of without any scaling artifacts is with native QHD videos. Where exactly are you going to get native 2560x1440 video? Haven't you ever noticed that other than the few 4k products available, all HD video sources top out at 1080p? I did a little looking and the cell phones that do 4k video don't even do QHD, at least they don't list it in their specs. This is probably because QHD isn't a standard video format. The standard video formats are 480i, 480p, 720p, 1080i (rarely used anymore), 1080p, and 4k UHD.
This means that unless you have some way of making your own native QHD videos, everything you ever watch will either be up converted from 1080p (or worse), or down converted from 4k. So any chance your beloved QHD screen would have ever had in displaying more visually perceptible detail than 1080p will be negated by scaling artifacts.
I find it comical that you demand a higher resolution screen, but I'm going to go out on a limb and guess you're perfectly fine streaming "1080p" to watch on your TV, Computer, tablet, or however you watch video at home. For such a demanding videophile such as yourself I'm surprised an inferior "1080p" online video stream would be "good enough" for you.
91. jos_031 (Posts: 56; Member since: 12 Jun 2012)
Humans can see pixels if the display is head so close up to 1200ppi...
103. TechieXP1969 (Posts: 2998; Member since: 25 Sep 2013)
When 1080p first appeared, there were few device capable beyond a Tv or computer for showing it. Now they are all coming much faster and content is available. Look for it. Stop watching YouTube. There are sites that stream 2K content natively.
11. rodneyej1 (Posts: 3576; Member since: 06 Jul 2013)
You're completely wrong.. Once you get your first 1080p display, look at it for a few hours, then look back at your old phone, you'll never repeat that again... And, looking at my 1520's 1080p display it's crazy better than the 768p display of my 920, but I can still see how it can be sharper around the edges of text, and stills.. QHD is no gimmick❕
13. zuckerboy (banned) (Posts: 898; Member since: 22 Dec 2011)
you r right when I look at s4's display after s3's display ; there is trully big difference. This difference can be identified easliy on internet broswer..
20. bigstrudel (Posts: 518; Member since: 20 Aug 2012)
Thats because when you take into account that the S3 shares 1 out of 3 pixels youre looking at a PPI down in the 200's. That's the reason that a couple years ago the One X's display was lauded as far superior than the S3 that was released months later. The display was never impressive to begin with.
42. lalalaman (Posts: 539; Member since: 19 Aug 2013)
well u r right but QHD only works with 5.5+ screen and not smaller than that imo...1520 is good enuf....but if these smartphones have larger screen then its not a gimmick
48. Droid_X_Doug (Posts: 5993; Member since: 22 Dec 2010)
The only question I have about QHD is what happens to the data allowance once 2k or 4k video content comes online in response to the new displays. A monthly 4Gb allowance gets tanked how far into a 4k movie?
4k video is awesome, no denying that fact.
72. chebner (Posts: 172; Member since: 17 Oct 2011)
4k will be awesome on a big a$$ TV.
But I hope 4k content isn't limited to streaming. 1080p streaming still hasn't matched BluRay video quality. How is it going to come close to true 4k anytime soon?
Don't get me started on audio quality of online streams.
19. Ashoaib (Posts: 2881; Member since: 15 Nov 2013)
What? 720p is ok? you cant see the significant difference between note 2's and note 3's screen? Really? Hmm.. probably, vision test required here. nice spectacle with correct glasses will do the job, plz try it
67. PressStart (Posts: 119; Member since: 08 Apr 2014)
I can understand that the best possible resolution isn't necessary, but there is an evolution of almost everything in this world. I think if the tech is there, it'll be used. It's a natural course towards the floating holographic UI display we see in science fiction films. We'll have those one day!
7. yowanvista (Posts: 340; Member since: 20 Sep 2011)
Such high resolutions are gimmicky, anything above 1080p is pointless on such small devices. Unless you've got cyborg eyes to notice the difference at the pixel level.
9. Bishop_99 (Posts: 74; Member since: 04 Dec 2013)
You don't need to see the individual pixels, it's not gimmicky. Play a full HD video on a Moto X and on an HTC One. You won't be able to see the individual pixels on either phones, but the HTC One will offer a much more sharper and detailed image.
The increased resolution here is not about being able to spot the individual pixels or not, but have all those pixels come together to offer a better picture quality.
23. Amir1 (Posts: 304; Member since: 20 Aug 2013)
Exactly. i don't know why some people fail to understand. is it too hard to understand? it's just like going from 720p to 1080p. thre is difference. it's not huge one for 5" display, but there is still difference. phablets will benefit more from 2k displays though.
26. bigstrudel (Posts: 518; Member since: 20 Aug 2012)
The issue is the performance and battery life tax for that small improvement. Other aspects of the display experience that are just as important can be improved without any added processor and GPU strain.
27. Bishop_99 (Posts: 74; Member since: 04 Dec 2013)
Yes, but only if the specs would remain exactly the same while increasing the resolution. That is not the case though, as the majority of these 1080p phones have outperformed their predecessor with a 720p display. The specs while be there so these higher resolution displays will outperform current 1080p phones.
30. bigstrudel (Posts: 518; Member since: 20 Aug 2012)
But the fact still remains. Less resolution = Less CPU/GPU strain and better battery life.
On newer hardware the point remains valid. The extra power of the newer processor could be utilized making the same resolution tax the system less leading to longer battery life.
31. Bishop_99 (Posts: 74; Member since: 04 Dec 2013)
That would go for any resolution though. If you brought it down to 720x480, it would run even better. I don't see what's the problem with increasing the resolution when we are going to get a better performing phone anyways.
17. zuckerboy (banned) (Posts: 898; Member since: 22 Dec 2011)
they said same thing for 1080p but now...
