[Q] Downscale Resolution to 1080p to increase performance?

For me QHD displays are too much for a 5.7 inch phone. The exynos version looks pretty powerful, but I guess I`d rather have better performance than insane ppi.
Watching some on/off screen GPU benchmark reviews for the LG G3, Oppo Find 7 and S5 "Premium", the off screen (1080p) tests had an average of 51% higher scores than on screen (QHD) scores. I mean, WOW! That`s a lot! I can post the results here if you want to skip the trouble looking for it.
One guy on youtube changed his LG G3 resolution from QHD to Full HD using NOMone Resolution Changer and used Xposed to change DPI and font scale of native apps to make them work.
What do you think about this? This could possibly increase overall performance+battery life and definitely increase gaming performance.
The videos about resolution downscale on the G3:

Sounds like you need to stay with your note 3

... and reduce resolution to 720p

and, no one cares about benchmarks..

and... lol reading above comments make me laugh
why you bought note 4 if you want to reduce it's resolution, there will be 1080p device later if you want SD805

Daaaaaamn, this a deal breaker... If I cannot reduce the resolution of the Note 4 to 4:3 CRT TV 480i letterbox... I will not buy it, what a piece of crap! I was hoping to get at least 6 months of battery life on each charge with CRT resolution... I reduced to 320i my note 3 and it lasts almost a year on a single charge. The only problem is that I am having issues watching YouTube in HD for some unknown reason.

funny stuff!
we ***** and moan that we want QHD/4K/ultra definition on our "5 inch video screens", then once we get it, we complain that it uses too much battery life, so we have to "downrez" it..
you just cant make some people happy...

I'm more curious of how the screen will look like if in 1080p, especially the pentile effect. We know that we still see the pentile effect somewhat on Note 3, not sure on Note 4's 1440p screen.
Don't really care about performance.

I can't see any difference, but I can't see any pentile on 1080p phones too so...

if you reduce resolution to 256 x 144 battery life will be improved by a factor of 10!
much better than 1080p! OMG!

Is there any sound reason for bashing the OP ?
Just because he thinks a little bit different than you, maybe a step ahead of you ?
His idea is no nonsense.
If it IS possible to boost perfomance by lowering the resolution to e. g. Full HD, that would be quite beneficial.
Practical example: Let's talk about a game, "World of Tanks - Blitz".
Great game on the PC, not so great game on Android. Reason: Graphics are not the best. At present, there's a kind of universal version out, all reduced graphics to make sure the game works with most Android devices, even the weaker ones. Game publisher said they're working on a version you can adapt to the performance of your system. Hope they won't lie.
2560 x 1440 pixels is quite a number.
Rendering that many pixels WILL take a lot of processing power, WILL be quite a burden on the CPU and the battery.
So the results are likely to be: Great graphics but bad performance - or bad graphics because the game recognizes the overall performance as being too low for high details AND fluid gameplay.
Plus: You can watch your battery going down in no time, as rendering that mass of pixels will take a lot of power.
Let's say we've got a resolution of 853 x 480. SOUNDS like subzero quality, but don't forget the tiny screen (compared with a large PC monitor).
If it's possible to display 853 x 480 using the highest details setting, the result will look classes better than 2560 x 1440 with low details. You won't be able to spot single pixels, just a wealth of fine graphics.
So a reduced resolution and highest details will look MUCH better than highest resolution and low details. That's benefit one.
Second, gameplay will be vastly improved by a higher framerate and more CPU power for handling all the netcode and stuff.
Third, our battery will last far longer because of the lower battery drain.
Result would be a great looking, blazing fast game which won't suck your battery dry in no time,
And that's a reason to laugh at the OP, for bashing him ?
I do NOT know if reducing the resolution AND saving ressources is possible.
But IF it's possible, it would be a great step forward.
You will NOT able to see the difference between full resolution and reduced resolution on the tiny Note 4's display.
Only differences will be graphics and details quality - and higher speed, better framerates, more fluid gameplay.
And there will be always some room for compromises like slightly higher resolution and the like.
Now bash on if you still feel like.

Just a bunch of trolls. There are many people dowscaling resolution to play. I personally leave at 1080p all the time. Just restart and everything rescales to the right dpi.

I don't know of a way to reduce it to 1080p, but wouldn't it make more sense to buy an s5? Battery life was superb on my s5, still wouldn't swap it for my note 4 though, optimise your note 4, it holds its own in terms of battery life and performance.

All depends on why you got a note4, I love the s-pen, I like the added fingerprint reader and heart rate monitor, and like the better camera with OIS. I already can't see the pixels on my Note3 though, so why would I care if I downgraded my Note4 to "only" that same resolution? Having longer battery life and higher performance for all the bits that matter to you sounds like a much better plan than having more pixels than you can possibly see.

You didn't get the idea at all. It's about making games run faster and with far better details. Same as with PC games.
Read my post!
Edit: It was me not reading the post correctly. Sorry !

I'd be interested in this also. I would love the ability to lower the resolution for a few apps I use on my note 4

I like this idea for performance in games and battery saving but you definitely can see the pixels on the Note3 and indeed any 1080p mobile right now. The extra resolution on the Note 4 really pays off for normal useage but games should be able to default to 1080p at the very least.
Phones should have a resolution change option like pc's these days anyway.

Sorry, I think you misunderstood. I was agreeing with you. My point was that I don't really "lose" anything if I downgrade the resolution as on a screen this size I can't see individual pixels even at 1080 I was also countering those who said the OP should have stuck with a note 3 by saying that the note 4 has many other improvements as well, and that the resolution, though better on paper doesn't really matter.

Yes, I indeed did - I did not read carefully enough.
Just added a comment to my post regarding this.
Thank you for pointing this out !

NOMone resolution changer in the app store lets you bring it down to 1080P.

Is there a way to lower the screen resolution from 1080p to 720p?

I hear they lower the res from 1440 to 1080 in the G3 so is there a way to lower the screen resolution in the G2 from 1080p to 720p?
I couldn't find anything about it in search.

Screen resolution of an lCD is a physical attribute, it cannot be changed. You can change the software to renderer the image so you would get a lower resolution data to show, and since android source is available, it is technically possible. I doubt anybody tried, because our device has a adequite computing power to generate 1080p images. On the other hand, lg g3 has almost same power, but it displays almost double size image. For g2, it won't worth the lost of quality.
The issue is, since LCD will display it on its physical resolution(there is no other way), your image quality will be far worse than the down sampled version. For example, if you render the sceen at 720p, and show it on a 720p 5.2" display, you will lose ~%55 of your data, but since you render your source on this resolution, will be sharp, just won't have so much detail. If you display this 720p image in 1080p display however, screen resolution cannot be changed, so your screen will try to calculate the missing %55, and then show you the result. Since there is no original data, it assumes the missing pixels were like the ones around them, which means your result will be blurry.
As a side note, old tube displays does not have a resolution, they can support various resolutions. We used to set resolution to our taste between speed and detail back then.

enigmanp covered the technical aspect of it and I'll just follow up with my own personal experience.
I had a chinese android tablet running at 2048x1536 resolution, the same resolution commonly found in iPad tablets.
My Android tablet sometimes perform sluggish because of the high resolution. Even though the CPU was a quad core 1Ghz, it's still chinese and the GPU wasn't great either. So I lowered the resolution and everything was blurred and not sharp at all (due to the reasons enigmamp explained above). I DID notice an improvement in overall speed, but apps started misbehaving and it was all a huge mess.
Now the only reason I did that was because I found my tablet lacking smoothness/performance. I just don't quite see why you'd want to do that on the G2 since the CPU and GPU can clearly handle even the most intensive 3D games on high detail. Could you please explain?

So why it doesn't get blurry on the G3 then?

If it's to save battery, I doubt you'll see much of a change.
The GPU is working on a smaller load but most of the time it's running at 200 MHz anyway. But I'm no expert, I'm just telling what I know and what I've experienced. I'll head over to the g3 thread to read more!

Reducing the number of pixels would help you to save battery if you are using a phone with AMOLED screen, sadly it is not the case with LG G2. So even by turning the resolution down, you are using pretty much the same amount of battery as you would with full 1080p resolution.
If you want to go ahead with it anyway, there are plenty of apps on the play store which does this. Just search "resolution" in the play store and you'll find them. However I don't think this will help your battery life at all, nor do I recommend it.

Late addition
Well, when i found out this was an option i just had to tinker. I have a G2 that is my daily driver and a S6 for back up. I changed it to 900x1600 480dpi and it works just fine. The camera touch focus is a little off, but otherwise it is sooper smooth now. I also throttle the CPU down. So both together I get a good experience and decent battery life. I know this is a late response, but to anyone out there with root and some lackluster performance might want to give this a shot. I needed to reboot once to correct some keyboard skewing. I also adjusted the height of the keyboard to compensate for the change in real estate. Works like a champ, no real noticeable degradation in viewing pics or videos. I'm going to try this on my Nook Hd+. It needs a shot in the arm (no pun intended).

download terminal
write in terminal :
su [ENTER]
wm size 720x1280 && wm density 220 [ENTER]
new density: new resolution * current dpi / old resolution ( for e.g. 720*1280*480/(1080*1920) = 213), altough i tested, and it seems that 240 is the best (for me), but it looks awful, for me, so i will go back to full hd + 410 dpi
ofc root required )
anyway, please share with us if it will be any battery life improvement

First of all, you shouldn't just change to an arbitrary resolution like that. You need it to scale by an integer number - 720p to 1080p means a scale of 1.5x, which will result in a bad quality image. Consider going to 540p instead - this means it'll be stretched horizontally 2x, and artifacts will be less visible. I'm unsure about battery improvements - upscaling will take place regardless so it may not be worth it because no proper testing has taken place. I'd instead consider using greenify, running an AOSP ROM without gapps (google play services are a huge battery drain) and other solutions to improve your battery.

Xperia Z5 Premium - Native resolution

Is it only me who thinks that all the videos online show the Z5 premium 4K screen at 1080p resolution ? For such a high pixel density the icons and menu should be much smaller and app list in the menu should be more than 4x5 .
I found a video showing the Z5 Premium running at a different resolution but much slower. I must admit I don't understand spanish but anyone can watch the end where things get really laggy ?
https://www.youtube.com/watch?v=qYn76ywh4tg

Old software running at 300 dpi. Will not be present in the finalized product

Have to admit that when I hear 4K I expect the resolution to be similar to the one in the video. It makes a huge difference and looks much better.

You look like expert of Sony and you have many xperia mobiles . I had one in the past, the Ultra T2 and although I liked everything about it that time, but sold it after 1 week becuse the low call voice in the loud speakers, althoigh the music was fine . I found out on the net, that may eb all Sony experia has this issue, may be thier standard.
Can you tell me if all the xperia you used has the same low call voice. I am thinking of buying C4 or may be the z5 , but I am afraid to have the same issue.
Thanks

Premium will not use 4k all the time, only when needed.

It's exactly like macbook pro retinas... you still have the desktop space of the standard resolution, yet much crispier

Almost no point of the Z5 Premium in that case, as my old laptop certainly isn't going to render it, nor is my 2010 spec plasma

Once you root it and have xposed installed I'm sure you can set a per app DPI. I can't use a phone if it doesn't have root (won't connect to headunit) and exposed makes everything so much better.

Even if that's the case, you are never going to browse and read at more than 480p. I've seen almost none apps for "simple" things going higher than 480p... Neither Chrome for browsing, nor Play Books for reading...for example!

it s smart management for speed & power
I don need 4K rendering when watching HD clips So It s better that phone switch to FHD/HD rendering

Lol u want to browse and read in 4K, but anything above 1080p is nearly undetectable for humans eye
4K will become standardised very soon, as VR goggles are getting more and more popular.
Now, on 1080p, when using VR goggles, the screen does get separated into two images. Thus screen resolution you see thru the glasses be like 400x800 or so..
Imagine, when using 4K... VR goggles will still display 2K.. Which is more pixels than our 1080p res.
Take a magnifier and look at a 1080p screen, count the pixels and multiply that by 2. That's the resolution you'll see thru VR goggles when using a 4k display, and that's exactly what it's designed and meant for.
Sooner or later, Sony will come up with their very own VR goggles like Samsung with VR gear.

I dont really understand what's with the "undetectable thing " people keep repeating.
If you browse at 4K, text is much smaller and the content displayed is much more than 1080p . I don't have to scroll 2 pages to see everything where I can see it in only one @4K.
When you buy bigger PC screen you get more space on your desktop ( icons / files etc.. ) because resolution gets higher not because the screen gets bigger.
Whether I can see the pixel or not is my least concern.

That's not about resolution.
Resolution is about pixels.
How things appear on the screen is about layout / DPI.
U can easily spoof ur DPI in build.prop or with an xposed module, even per-app.
Just Google a bit and you'll find out

Higher DPI means higher resolution....
In the first video I posted the dpi was increased as u can see in the end of the video the device becomes very laggy during transition.
bottom line, xperia can't handle 4K resolution.

Marshmallow and Always-On 4K

Since Marshmallow supports 4K display at all times on the home screen, etc., it seems that this phone could do 4K all the time.
I've read that some believe they won't even turn it on for Marshmallow because if the CPU/battery drain.
Two questions:
1. Does anyone agree or disagree with this? Maybe it will at least be a setting (in developer options)?
2. If they don't turn this on for Marshmallow and it runs like Lollipop on "Full HD", could a custom ROM enable permanent 4K? Or rooting? Would this even be possible?
Thanks!

Bet that you will return to FHD mode when you look at the battery anyway. Plus most icon resources inside apk will almost certainly stick to xxhdpi (around 480dpi) which won't bring any advantage on 4k screen.

I don't care about battery life. Anyway, does anyone have any answers/guesses to my questions?
Sent from my E6883 using Tapatalk

Well to answer your questions :
1. I disagree as per my answer, it is just not viable for the battery life and plus iirc when i read marshmallow changelog, it only states that it supports 4k but doesn't say anything about native resolution and apk resource resolution addition, the changelog only specifies that it is natively supported but in an upscaled way.
2. If anything, nothing is impossible. But not everything is viable.

Doing QHD at all times and 4K during media is fine by me.
Do it Sony.

I hope via root is possible.
About battery life, I have nice battery packs that maintain the charge for the whole day .....and I suggest any intense user of smartphones having one o more too

Marshmellow comes with native 4k support which will allow developers to turn on 4k on demand.
I don't see a reason to have the the 4k display always on unless its for gaming/movies/viewing high res pics.

What if Sony can let the user decide which resolution their phones wanna run.
Like windows in a separate setting under display user get the ability to select the resolution.
People who don't care 4K they can use FHD and if they like 2K they can have 2K , if not 4K all the time.
But by default gallery and movie apps upscale the content to 4K. I think if they can pull that off it'd be so cool.

Yeah, should be offer 2 modes in display setting, quality and battery life.

4k is already possible! thanks to the guide from the previous post lol, I was able to take a screenshot of my phone running in 4k using a different screenshot app

But the important one is the dpi though. The 3840x2160 means it's physical pixel count isn't it? But when you look at the density it's obvious that it's still 1920x1080. Cmiiw though.

Are there third party apps that run in 4k mode?
Netflix? Ultraflix? Riptide gp all run in 4k on my shield tv

As hansip87 said.
Also running 4k all the time will increase the phone warmth in hand - try it yourself while watching a 4k movie for an 1h30min
I think it's great that it's possible to run at 2k and 4k all the time but for me it's Battery life others is screen quality /viewing pleasure

After performing the wm size and wm density as shown in the thread fesar posted earlier in this thread, I stumbled upon a few problems that persisted even after restoring to default.
You can read more about my rather bad experiences in the mentioned thread.
