Hi! i have a question... there is any option/app to, like on PC, when any full screen software do not have your resolution, not resize the app to the screen?
because, i think the worst defect of the wildfire is the non standard resolution, and a lot of apps do not have this resolution... and i think this causes some apps not to work very well, specially games...
i dont know if im explaining myself (my english is not very good)
No, its the app that must support the resolution. You can use apps like LCD Density Changer to give the effect of a higher resolution, but that is hardly optimal.
This is why there are complaints everywhere about Android Fragmentation. There is no standard set of requirements, which leads to issues like these (Only for low end devices though)
Lastly, the games not playing is more because of the grandfather-age hardware and no GPU on the phone. Not the resolution.
1080p contend is supported more often from apps because of the amount of supported devices, I wondered if downscaling the tablet's screen resolution to 1080p is supported by any rom and if it would save a few hours of extra usage to the tablet?

I am no expert but I know that when you give the command to change the resolution it doesn't actually change it, it's more of a virtual/spoofing, to make the system think it's changed. So all the pixels will still be there. But when watching videos in 1080p the "upscaling" won't take much of your battery, if any at all. You won't notice it.
A digital screen only has 1 resolution. To use any alternate resolution it must be scaled to the screens native resolution so if you were to somehow force a resolution other then the native it would have to re-scale it to the native in order to display it which would require additional processing...
You could get better performance, in 3D applications for example but not better battery life.
I am asking for the SoC power consumption,logic says less effort saves more energy,current pixels to handle are about 4 million instead of the half that 1080p are
Though there might be needed optimizations as a modded kernel with different clock speeds

"Logic" that's ill-informed can be just as fallacious as a random guess. Your particular brand is working off of some very silly assumptions, and your second sentence really just highlights that. A modded kernel with different clock speeds? Please.
When you downscale an image, you have less pixels to handle only in the sense that the image becomes smaller. The actual display still requires that all of the physical pixels be addressed before it can display anything. The only reason that you see graphical performance improve in say, a computer video game when you're playing on a lower resolution is when the bottleneck is the graphics card rendering an image. If your computer is struggling with the output, then you have a different set of problems.
On a tablet, a game that's not built to the screen resolution (let's say it's designed for a 720p panel for the sake of argument) will keep load fairly light on the GPU for rendering, but the same amount of work as normal to display (although this is a simplification, it'll work for these purposes). That's because whether the content is 720p or 1080p doesn't matter-- the GPU still needs to figure out how to stretch it to the dimensions of the physical screen.
Bottom line, you're not going to save "a few hours" of usage. All the work you'd need to do normally will still be there, plus the chicanery of trying to transform all video output to 1080p again only for the physical screen to demand its normal resolution.
How do you explain the 3rd ipad (that your sighn shows you have) overheat from the SoC?The amount of retina display pixels caused it and overheat means power loss as far as I know.Anyway your ironic first setence made me loose any interest for rest of your post.

This! I know I was playing Dead trigger and you can enable the advanced graphics for tegra gpus, and it was laggy, but after reducing the resolution (the game doesn't allow this, or didn't the last time I played it) the game was buttery smooth.
And no, video decoding doesn't care what resolution your screen is. It still has to decode the whole video and display all the pixels, weather they are upscaled or not. your battery won't be affected by that. Apps on the other hand, like games, are another story.

Not sure what's worse, clueless people on a site called XDA-Developers or clueless people who refuse to listen to advice.
Whether the iPad has some kind of overheating issue is a completely different matter and can be caused by a number of things. The fact is that changing your screen's render resolution has almost no impact on your battery life. The GPU still has to upscale whatever is rendered to the Nexus 10's native resolution. The biggest drain on the battery is the display itself; it takes a lot of energy to light up a display with such a high pixel density and still be bright enough to see.
Irony is the worst of all,at least some people know what a question is as this thread is
When you ask a question you need to be able to accept an answer that isn't on your liking. You've had 5 people telling you in different ways that it won't help, if you don't want to believe us, then here you go this doesn't work on 4.3, just 4.2 and maybe earlier. You can change it and use it for a week and see for yourself. Just make sure you don't let autosuggestion cloud your judgement.
It's not the answer but some persons that give them that's not my liking

Ahaha, says the new member who has demonstrated 1) that they don't know what irony is, and 2) that they have no idea how to ask for help. Hint: it's not "please validate my preconceptions." The only irony here is your reactions to the thread that you spawned.
My iPad has never overheated, or even come close, really. It's the same crowd of people who will complain any device "overheats" when they're doing something that is going to create thermal load. Newsflash: that will be just about any game or long-term video ever. The 1080p Nexus 7 gets warm under use as well-- oh wait, 1080p is some magical resolution that will fix all your woes, right?
Protip: overheating doesn't mean power loss unless your circuitry gets pushed outside of standard operating conditions and loses conductivity due to thermal deformation. On a desktop PC, it might mean power loss from running the fans up, but as mobile SoCs use passive dissipation, this is a non-starter. Heat buildup is a byproduct of using a processor to do things.
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.

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.
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).

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

Now I miss those glory days of correcting CRT display alignment and freedom to changes aspect ratio/resolution beyond the DAC supported rate at the expense of mild irreversible eye's retina damage. Lol. :laugh:
Hi all,
I personally don't think there's much difference between 2.5K and 1080p on a ~5 inch display. Has anyone with root found a way to and tried down scaling the display output to 1080p?
If so do you notice any visible difference and has it noticeably improved battery life?
I'm not convinced how much difference it would make as the display itself would still be physically outputting 2.5K pixels but at least the processing side of things would only need to push 1080p.
Thanks!

I searched for an answer to the same question. I doubt it's have much impact on battery life honestly. The gpu isn't working as hard, but that's not the biggest drain by far. The best reason to do this would be improved performance in gpu-intensive activities like gaming. However with this phone that hardly seems necessary.
(I suppose, theoretically, you might get better battery life during gaming)
1080p won't look nice on this screeeen

My guess is the won't matter because the GPU will need to work just as hard. The number of pixels you push to the screen will always need to be converted to the number of pixels the screen is designed for. Pixels are more hardware related than software related.
A screen has several tiny LED's that illuminate to display the image on the screen. The 6p resolution is 2560x1440 which equates to roughly 3.7 million pixels. It has to display 3.7 million pixels. 1080 equates 2.1 million pixels but the 6p has to display 3.7 even if you only push 2.1 million pixels to it.
Depending on how well the Android OS is designed it wouldn't be out of the realm of reason to say that dropping the resolution to 1080 might reduce battery life instead of save it depending on how well the code is reused internally and where the interpretation of scaling happens in the chain.
I talk out my ass a lot so I am only guessing that the above is true.
Downscaling to 1080p won't do much for battery , the pixels still need to be lit, but the GPU will be less stressed, it doesn't have to render those extra pixels with new information, its just upscales

That's my understanding as well. It's still rendering at lower resolution, which requires less from the gpu, but then upscales to the native resolution. I'd still suspect this will improve battery while gaming, but not in general use. Entirely direction though.
It won´t look good on the screen, that´s for sure. Downscaling might only be needed if you want to play a heavy game which wouldn´t run fluid enough on the Nexus 6P, due to hardware limitations.
