[Galaxy Note 4 Q&A, Help & Troubleshooting] Chefproll:
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.
[Galaxy Note 4 Q&A, Help & Troubleshooting] dlads:
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.
[Galaxy Note 4 Q&A, Help & Troubleshooting] ve6rah:
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.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Chefproll:
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 ! ;)
[Galaxy Note 4 Q&A, Help & Troubleshooting] Slither2006:
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
[Galaxy Note 4 Q&A, Help & Troubleshooting] Jonathan-H:
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.
[Galaxy Note 4 Q&A, Help & Troubleshooting] ve6rah:
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.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Chefproll:
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 ! :)

[Galaxy Note 4 Q&A, Help & Troubleshooting] Slither2006:
Have you tried this? I'm a bit reluctant to try CF-Root for my SM-910G model note 4 without knowing if there is an actual performance gain or not. From what I've heard there isn't but I'd like someone to confirm this.

Back in the day of Samsung Galaxy S2 there used to be a CF-Rooted kernel for nearly every firmware revision. There only appears to be an Asia CF-Rooted kernel for my 910G model and I don't event know what firmware the kernel is from.

Here's the link with all CF-Root kernels for Note 4 so far :

I want to change Resolution to 1080p. What DPI?

Using NOMone Resolution Changer from the Play Store what DPI should I set the Note 4 so that the phone runs at 1080p resolution without making the system elements like notification quick toggles massive and other UI elements out of proportion.

What DPI settings should be set so that phone would run just like Note 3 screen wize?
[Galaxy Note 4 Q&A, Help & Troubleshooting] TheCuriousOne:
Just tested it at normal and full HD settings using antutu. Don't normally judge a phone using benchmarks but the difference is spectacular.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Slither2006:
I bit the bullet and installed Nadia Kernel on my ANK3 vodafone AU stock rom. I've tried the NOMone Res Changer also and haven't found a DPI I can use for 1080p.

That's good news!

---------- Post added at 11:47 AM ---------- Previous post was at 10:53 AM ----------

I've managed to configure my screen at 1080p with a DPI setting that appear correct or as close to correct as the DPI was for 2560x1440.

Note : I'm running the stock samsung rom ANK3.

1. I installed the Xposed Framework.

2. I installed and activated the "App Settings" module (search modules in xposed app)

3. Installed NOMone Resolution Changer from playstore

4. Opened the "App Settings" module application and changed the DPI for "Android System" and "System UI" to 480.

5. Rebooted phone

6. Opened NOMone Resolution Changer and applied the setting 1080x1920 480 DPI

Stock samsung apps appear to display and function correctly. I've only tested the camera, phone, s fit and s view(flip cover) so far. Play store apps appear to display normal also.

This is purely an experiment to see if there's any difference in 3D performance mainly. I'm not expecting much change in battery life.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Ed Law:
Hey guys

At the moment I am still using my note 3 and note 4, both as daily drivers. The note 4 is for personal use and the note 3 if for work. Even though work gave me an iPhone 5, I just can't handle it.

One thing I have noticed recently is when i check my note 4 battery stats and compare them to the note 3 battery stats (after similar use and Screen on time), the note 4 almost always has the screen as the biggest battery drainer. Where as, on the note 3, the screen is often way down the list consuming 1-2%. Granted, I am using lollipop on my note 3. But i didn't think it would be such a big difference in battery use for the screen. Hence why I decided to look up if there is a way to reduce the resolution of the note 4 screen and system (because i have concluded that it must be the resolution of the screen that is causing the phone to eat so much battery life). My search is what took me to this thread.

Though I understand a lot of the responses on this thread, the fact is, if there was a way to manually control the resolution of the system ui and screen, I would almost certainly at least give it a go. Even if all it meant was I would get a little more control over my device, i would still do it. Freedom of choice and the ability to customize is generally one of the reasons why we chose Android/Samsung to begin with. So I would have to stand on the OP side based on this alone.

However, I do think that reducing the screen resolution would reduce battery consumption by up to 20% or even more. And this is based solely on the fact that more pixels equals more power. And reducing the resolution to 1080p really isnt that bad. Sure, its not as fancy as 1440p but most people probably couldnt even tell the difference if you asked them to. But most people could tell the difference between 10 hours battery life and 15 hours battery life.

So my post really doesnt have much to add to this thread except to say, dont be so hard on the OP because being able to control our devices and customise its settings is pretty much why we are all here :)

Im looking forward to finding the answer tot he OP's question.

I will give the above tricks a shot and report my results when i get the chance :)
[Galaxy Note 4 Q&A, Help & Troubleshooting] Slither2006:
I ran 3dMark's mobile benchmark app and with Nadia kernel r4 I got the following results :

Screen at 1440p CPU interactive GPU interactive - ~12100

Screen at 1440p CPU performance GPU performance - ~14000

Screen at 1080p CPU performance GPU performance - ~16000

Screen at 720p CPU performance GPU performance - ~19100

I found these results quite strange. The 3dmark mobile app reports that the APQ8084 processor in the note 4 is supposed to achieve benchmark results of 19000+. I'm not sure how they got that result. I've tried disabling Samsung DVFS and setting governors to performance but my phone struggled.

I'm currently running N4 AEL kernel r6.2 and with similar governor settings I get an even lower ~11000 at 1440p so I'm not sure what to believe at this point.
[Galaxy Note 4 Q&A, Help & Troubleshooting] gabrielgon:
Great to see all the discussion. I started the thread before having the phone and after testing for quite some time I can confirm what some people stated:

-You can use at 1080p all the time with everything on its place. Set for 1080p and 480dpi with nomone and restart. If needed, restart again.

-The gaming performance improvement is there. This is 100% confirmed. It just varies how much you'll gain from game to game.

-As you lower the resolution, the image starts to get blurred, but as the physical resolution is the same, you'll never see the pixels (I went all the way to 720p for the sake of testing and the texts are pretty blurred).

I can't say much about battery as my phone gets 6 sot if I don't game, so that's more than enough to me.

Thanks for the posts, I thought for a little while I was the only one. :)

Just 2 thing...

After change and save resultion need 2 restart for the full 1080p.

Ok there is a perfomance boost but not something great to brag about antutu score was more or less the same no changes there and i believe there was a less power consumption when i was playing some games gonna test this for some days to see if it gets me through the day without charging in the night see how it goes in a normal day of mine or so to speak but it would be great as an idea if this was possible saving more power that is by reducing the resolution.. I hope this will work better with lollipop when it comes out.

I moved long ago to Google's keyboard so I didn't notice anything in that direction. I still have some stutter while filming but I definitely notice battery drain (absence of) and I'm still trying to see if I can recognize a difference between 1440p and full HD. One has to restart the phone for everything to be properly aligned.

Tried putting it on 480 450 and 400 still the action memo window shows bigger but when I try to resize it it turns way smaller so it's no big deal I can live with this tried rebooting after each change twice like you said nada I'm also on google keyboard so feeling some material love now :P. Still this is a very good find performance and battery wise! I also made the whole system except a few system apps run on 400dpi multitasking seems better this way. [MENTION=1175741]TheCuriousOne[/MENTION] among other things I believe that the screens output is less detailed equals to less power and more performance but I guess you already know that. It's like putting side by side lg g flex and note 3 the one is 1080p and the other on 720 but with the same processing power the result is better performance for g flex since the screen is on 720 but the thing is here what about the PPI right? Has any effect reducing the resolution to the ppi?
[Galaxy Note 4 Q&A, Help & Troubleshooting] yussuf007:
Im only found the performance boost.

I got in antutu 51k whit 1440p and 56k whit 1080p

And the overall performance in FHD is very very good, but i dont know why i dont see any difference in battery life.
[Galaxy Note 4 Q&A, Help & Troubleshooting] sephkateno:
I'm not sure about this but maybe its because we did lower the resolution but the same amount of PPI is used to power the screen none the less just guessing here. How did you get 56 k in antutu I got the same results...what ROM are you on?
[Galaxy Note 4 Q&A, Help & Troubleshooting] TheCuriousOne:
I reckon you might right.
[Galaxy Note 4 Q&A, Help & Troubleshooting] crigztina:
Some apps don't work at QHD.

Increasing performance is not the only reason, not even the most important.

TomTom for example does not work above 1080. I am looking for a way to make it work lowering the screen resolution.

And by the way, I think 2500x1440 is a waste in a screen of 6" or less. Even 1080 might be a waste. I'd need a magnifying glass to see the pixels even at 1080, so why 1440? I am not even able to see the pixels in my former note 2 with 720p, and the move to the note 4 has not been motivated for its large resolution at all, in fact, I considered it a disadvantage, a waste.

Well, I'm trying to find a way to make TomTom work, and for that I need to lower the resolution. I hope to find a way. I'd happily lower the resolution to 1080 or even to 720 permanently if I could.

Also I found that Real Racing 3, for exacmple, runs worse in the note 4 than in the note 2, even when the former has more CPU and GPU power. In the note 4 it stutters too much. But that's less important than the problem with TomTom, at least for me.

Yes, that's why Samsung keeps bumping the screen resolution, that why the upcoming Note 5 should bring a 4K display, and I know ill keep reading the same crap, why 4K display?? 4K display is a waste of pixels bla bla bla bla, its because when you use the Gear VR even on a 2K display, you can still see the pixels, theres a reason for everything and all I see is people crying cuz of the screen resolution, just wait for the Note 5 4K display, why 4k?? that's a gimmick, no, its not, its because it has a purpose, the Note 4 its a phablet but its also needed for the Gear VR headset, as well as the upcoming Note 5.

Sorry to kind of necro this thread, but there is a way of lowering the resolution without being rooted.. Sort of. It will lower it for apps and games but the phone will still upscale to the regular resolution. Helps performance in games but doesn't change battery life.

Note 4 is capable as is. Better battery life is only benefit I've found is changing resolution (might be placebo). Performance has been solid on all games. What may impact gaming more than anything is the Android version. 4.4.4 < 5.1.1 < 5.0.1. Have yet to test combination 5.1.1 bootloader, kernel, rom combination but reports from other members sound promising.

[Nexus 5 Q&A, Help & Troubleshooting] raptir:
As far as I know you won't be able to run the 3.14 kernel on Android 4.4. There is support for zram in Android 4.4 so you should not need to update the kernel anyway. Support for zram was added to the linux kernel mainline in 3.14 but the module is compatible back to 2.something. The following link gives some details on enabling it.

https://source.android.com/devices/low-ram.html

That said, I'm not sure why you would want to use zram on the Nexus 5. zram is really designed for low memory devices, and the Nexus 5 has a good bit of RAM to run Android. Are you running out of RAM on your Nexus 5? zram will actually decrease system performance because it puts a heavier load on the CPU for compression and should only be used if you do not have enough RAM to run the system.
[Nexus 5 Q&A, Help & Troubleshooting] zxcoolid:
Firstly, thanks for your reply! I want to enable zram on Nexus 5 for some special experiments I'm conducting.

And yeah, it is said there is support for zram in Android 4.4. But I just wondering how I can enable it with the old kernel version on Android 4.4. The link you provide I have seen before, which also need to compile the kernel adding zram config.

What do you mean the compatible zram module. You mean we can compile the zram module first and insmod the module?

Thanks again!
