1440 x 2560 pixel resolution (QHD) displays: yay or nay?

1440 x 2560 pixel resolution (QHD) displays: yay or nay?
Like many things in this industry, it usually takes one company to take a step forward for the rest to follow through onto the next 'thing'. No guarantees as of yet, but it sure seems like super-dense, 1440 x 2560 pixel resolution (QHD) displays are next on the agenda of Android-based manufacturers. That's not surprising. As mobile hardware becomes more and more ubiquitous, brand name vendors need to continue justifying the need for consumers to upgrade their existing devices. Increasingly so.

QHD displays, in that sense, appear to be a no-brainer. Everyone digs sharp displays, and sharper is better than just sharp (1080p screens in this scenario). The question is: do these truly provide extra value to us, the consumer base?

We'll be honest and admit that we still haven't had the chance to handle any of the current crop of QHD devices (that will change very soon, though), so the following is nothing more than a preliminary opinion. That said, it appears to us that QHD screens entail a whole bunch of compromises, none of which are trivial. 

For starters, more pixels pretty much automatically mean more processing power will be needed to achieve a given level of performance, so the chipset in your latest flagship will have to work extra hard to provide you with a worthy flagship user experience. In result, battery efficiency will go down -- a most unpleasant downside, all things considered. What's more, it's unlikely that you'll actually be able to discern any extra fine detail unless you hold your phone really close to your face. Lastly, until the new tech matures, such panels will cost more to make, and yields will be comparatively lower. Unless manufacturers agree to stomach these costs increases themselves, it might mean consumers will have to bear them.

Obviously, the above sounds like a very one-sided take on the issue, and that's precisely what it is. Again, we still can't speak for sure, but it would appear that QHD displays only make sense in true phablet-sized devices (and that's around the 6-inch mark nowadays), where the extra screen real estate will require more pixels to offer a pixel pitch comparable with the best out there. Do you agree?

Possibly, but...

I'll wait to see if there's a truly noticeable difference when used at a normal viewing distance and what kind of impact 'pushing all those extra pixels' has on battery longevity.

1080p looks so good at this point that I'd likely rather the focus go into improving battery life/display efficiency than packing in more pixels.

Yes

Most of people said no when 1080p was coming in phones. 720p was enough.

We will see great battery technology ahead, don't worry. QHD is great, just like TV got 4K.

Wait another 2years for that. No Oems want to use advanced tech due to being expensive. What they will do is use a 3500+mah.

Comparing Tv to a 5inch screen is a big diffrence due to Tv's using less ppi than using high ppi on small screens

Look at the S5 vs Note3 screen, big difference what ppi can do.

1080p/1200p resolution is great for displays up to 7" and 1440p/1800p is great for 8" and bigger displays...higher resolution takes toll on performance...gpu has to work harder to push extra pixels...need more memory bandwidth to push data in display buffers...and not to forget...all this drains battery quite fast.

With a resolution at this size, there would also be an "increased Cpu and battery drainage.". The number of PPI at this size makes it pointless.

I would like to see a Blind test where people are asked to identify which phone has 1080p display and which one has over it... All bezels covered, only the same picture being displayed and you can only look from the same distance without any help (magnifying glass)...

I would love too see how many "average" persons would get it right...

My guess is that over 350ppi at 12" (30 cm) nobody would really notice... so even 720p can get into play.

1080p for phones under 6" is a battery killer, 1440p for devices under 8" screen is also a battery killer.... But since everyone is doing 440ppi... I would be ok with 1440p at 6" screens minimum.

I hope the LG G-Flex 2 has a huge 6 inch OLED QHD Screen. I got a chance to play with the phone and OMG, there is no other phone that has better looking videos... I swear that screen was build exclusively for watching videos because for anything else, it's NAH.... And below 80% brightness...the screen slightly ghosts around... It ain't bad but for a phone that is that expensive I'd expect more.

I don't mind devices having QHD screens. I'm sure other people would still buy them. Besides, if it becomes popular, it would bring down the price of 1080p screens, so more hurray for the midrange/low-end market

I would rather that manufacturers spend more time making the current res displays "better". We are switching display resolutions so quickly that I don't think we are maximizing potential.

I'd rather see companies try and make the best 1080p displays they can. Perfect colour accuracy, work on better minimum and maximum brightness levels, keep colour temperature good, have less bleeding in displays, etc...

There is a strange vibe in mobile (especially in Android) that 'more=better'. I don't think that's always true, and I'd prefer we see companies improve on what we have, rather than keep going with the spec race.

I think the best option, in that scenario, would be if we had the option to calibrate the displays on our phones, the same way we calibrate the displays on our TV's. Provide a great screen by the OEM and give us the option to completely control and calibrate even simple things as contrast, color, color temperature, gamma, sharpness etc.

Instead of only having the setting set forward by the OEM's, we could properly adjust it to our liking.

Also they should provide the same option with CPU and GPU have the "Turbo Mode" button for extreme multitasking like on the i5 and i7 intel Socs.

Couldn't agree more. Different people see things differently and like different setups. For example, I much prefer a cooler display to a warm one.

This is a great point as this would be a feature that would definitely get me interested in a device. Nicely put!

We heard the battery argument when screens went from wvga to 720p, and again when they went to 1080p - and it didn't happen. Each successive generation of hardware is more power efficient such that battery life is equal or better.

Let's say with 2k the battery is same as it is now with 1080p, I would still rather take 1080p and get even more awesome battery life than getting higher res screen when it's most likely to be less noticeably If at all compared to the jump from 720p to 1080p.

Super yay. It's not the high pixel count, because the pixels greatly change depending on screen size for the same resolution. It's yay for me because 2560x1440 display are being brought onto our phones.

For those that don't care about screen resolutions much, the 1280x720 and 1920x1080 displays aren't going away. So people will have even more options now.

Precisely!

We are going to see more low ends coming with 4-4.5inch HD720P displays, Mid ends and some high ends with HD1080P displays and then premium high ends with QHD :)

This is a good thing for the low end, where we are going to start seeing High PPI displays there, as the HD720P displays become cheaper to make.

I wish that would be the case but something tells me we will still be seeing 480x800 res screens and 960x540 screens. Regardless how much cheaper 720p gets, those other screens will be much cheaper and most oems when building a low end budget device will almost always go for the cheapest parts.

This article is one of a constant reminder that the battery is the most critical component of a mobile DC powered device. Smartphones are getting larger. Chips are becoming more powerful. Screens becoming more vivid and clear. Yet, in the midst of obtaining all this technological advancements, the best we can hope for is sticking a larger battery inside. No new battery advancements whatsoever. Same 30 year old technology. Just making them larger to accommodate larger devices. Those that complain about battery life on a single charge, should think about carrying an Automotive 12v battery tethered to the phone.

We want thinner and lighter. We want faster and more powerful. We want larger and brighter screens. But what about the battery? Do we really want to settle for 30 year old technology in today's devices? Now we seal the most vulnerable component in a device that we can't replace? Let's concentrate on perfecting the power source first before adding more features that degrade the subject of most concern; the battery.

Show me some QHD content and maybe I'll say it's worth it. For now, it's the only bad thing about the LG G3: a 1080p screen would probably get even more battery life than whatever it gets now (which, knowing LG, is probably excellent battery life).

Looking forward to my Note 4 with 5.7inch QHD SuperAMOLED. The battery should be larger, the CPU should be more power efficient, and it should give similar if not better battery life than the Note 3, so I'm happy :D

Most of the video content is 1080p and the phone records 4k, watching 1080p on a 2k display is a bad experience compared to 1080p display because the video is stretched with indefinite pixel marking. a 1080p display can display 4k because the marking is a clear 1:4 ratio. sorry pixel peepers, for me its either 1080p or 4k and nothing in between

The youtube you watch on your 1080p phone is really 720p. Unless you only watch 1080p videos on the phones, most streaming services to your phone is 720p. In reality, you are probably mostly seeing 720p video most of the time on your phone, depends on your source.

The aspect ratio of the video determines the size, and these phones don't need to stretch out the video at all, all it would do is upconvert it. A proper 1080p video, like one from a Blu-ray, would upconvert much better to a 1440p display, than a highly compressed 1080p video. Besides, now with these phones recording in 2160p, these videos only have to be downconverted to 1440p and not further down to 1080p.

Technology would become stagnant, we wouldn't be moving forward then just like apple, how many times did they change their resolution, just once I believe and they were forced to do so, otherwise they would still have a resolution of 480×320 pathetic!

According to a large variety of polls worldwide, nothing is more important than battery life. That's why AMOLED displays will always have an edge (especially when they are are good as the one on the Galaxy S5) and that's why anything above 1080 is counterproductive. This being said, because our irrational self always prevails over mere logic, like everyone else I must confess that I would be excited to get a 2k display on one of my smartphones (and, why not, a 4k display... like on the Galaxy S6 probably coupled with a 64-bit 8-core Snapdragon 810...).

I'll say Yay for this one, but I'm not 100% convinced and I'll wait until I get my G3 to say for sure. But I swear if these guys try going higher next year, it'll be a big fat no.

Maybe they could have it switch on-the-fly to a lower resolution in a power saving mode. Being QHD you can run at 720p with simple pixel doubling. There are already apps that can change the display resolution so it shouldn't be difficult to implement if it really does significantly affect battery life.

There is NO way to increase resolution without decreasing battery life and increasing display lag (if there's a dedicated GPU) or general phone speed (if there isn't). A phone's processors can only crank out a fixed number of FLOPS (floating logical operation per second). Each operation takes time and consumes energy.

It might not make much of an improvement but, given the choice, I'd rather have more battery and a faster phone/display. 4K or even 8K on a 60" screen is worth it. 1080p on a 5" screen is more than enough.

Remember: TANSTAAFP - there ain't no such thing as a free pixel.

I like the fact that high Tech video scren tech is advancing and you can bet your butt an OEM will put these high pixel screens on a device but if theses new high tech high pixel density screens eat up too much battery life they will be put on Desktop Computers which are connected to a power receptacle on a wall socket. I would love to have a 24 inch Monitor with a 1440 X 2560. I Use my desktop computer every day Folks Tablet computers are OK but most people want to see video, movies and play high def Games on a Nice 1080P 24inch
high def Monitor. The PC desktop computer I predict will never die because a Tablet is a fixed specification device what you buy is what you get FOREVER! On a desktop PC you can upgrade it through it's PCI or PCI express 1 or 2 slots and hook it up to a nice 24 to 27 inch 1080p Monitor or to your big ASS 60 inch HDTV.

720p is too little, 1080p is excellent, 1440p is excellent also, although if I had to choose between the two, 1080p would still be my choice unless its a Super AMOLED 1440p then sure why not...it just seems like the GPU would be power hungry though but otherwise that gorgeous 1440p ....

I have 1080p 5" phone, 1080p 7" tablet, brother has 1080p 8" tablet and on every single one from a normal viewing distant, they all look just as sharp as one another. Sure once you start literally putting eyeballs to screens or in the tablet case only a couple inches away you may see slight sharpness decrease but imo if to see pixels you have to go pass the normal viewing distance by more than an inch then it doesn't matter. It's like my TV, from my sofa I can't see no pixels but if I go close up I can see pixels. It doesn't matter as Long as it's sharp from my sofa. Lol am going round and round, point is give me 1080p screen in a phone any day over 2k because I would rather have the better battery life, better performance etc than boast about pixels that won't make a difference in normal view other than under a magnifying glass.
