So I'm having a hard time understanding all that's going on with DPI and resolution. My primary end goal is I want to be able to change my resolution or DPI which ever is correct for performance and battery reasons. I want to upgrade to the pixle XL when it comes out but I care about maximizing battery life more than o care about a quad HD screen. I plan on rooting.
So my question is what is the difference between DPI and resolution. I've seen a few different DPI changer apps, but it seems these are more scaling. I read a little on this thread, http://forum.xda-developers.com/show...4783&nocache=1
But it seems he's changing the resolution? And then adjusting the DPI to scale things correctly?
Basically I want to be able to run 1080p on a quad HD phone without making everything huge or tiny, however it would throw things off. Thanks for any help!

The Nexus One and Nexus S both had the same resolution (800 x 480) which makes sense for a reference device as having a stable target for UI / display is beneficial to developers. It allows them to acclimate to a certain resolution to produce the best looking apps available. They seem to have ditched tradition (and sensibility) by going from 1280 x 720 to 768 in a year, different resolution, different aspect ratio.
Personally I find that there isn't enough vertical resolution what with the navbar and status bar so it all seems kind of silly.
Perhaps Google is going to do something new with the increased lateral resolution?
I am not a developer so correct me if I am wrong, but doesn't the android SDK have some sort of implementation that makes apps compatible with a lot of screen sizes and resolution? So I don't think changing the resolution will matter so much.
Hello fellow HTC users,
The biggest issue I've had with this phone has definitely been the resolution. It's just way too low. While the software tries to compensate, it just cannot do it. The pixels are too large not to be noticed and quite frankly, bothered by it. I have installed an app to up the resolution on my phone following an advice from another member on this forum. I tried plenty but NoMone seems to be the best app for it. Of course, you'll need root to do this but I assume most of you have it just by being here.
You can get the app here: NoMone Resolution Changer
I played with a lot of different resolutions and DPIs. When I use 720p or anything above, the phone starts to suffer real bad. It just isn't able to handle it. The best one resolution I found, after doing some calculations and using some apps as a guide such as Resolution Tool, which has various options to calculate the resolution and DPI. I found it to be:
Width: 725
Height: 1282
DPI: 315
This one looks really great and the phone performs wonderfully.
If anyone is looking to tweak their resolutions a bit, I would advise you try this one. You'll be glad you did. The resolution upholds the 16x9 ratio, which is the ratio the screen was designed for.

I tried switching my screen to this resolution but the entire screen looks smaller. Do you have any other resolutions I could switch to?
Pointless. Adjust DPI instead. This causes your phone to attempt to scale the virtual display to the physical, and effectively causes the lag and slowness described.
Hi,
1st off I love this phone. I am extremely pleased and have zero complaints so far. Buttery smooth too....
My Question is how is it possible that the screen resolution is adjustable? Does the display turn off pixels? Does it merge pixels? Please enlighten me..
Thanks,
Joel
I'm pretty sure it must be 'rooted' first to allow those changes.

Sorry even though u r pretty sure. This info is wrong. U DON'T need root. Just like samsung graxe ui. On LG V30 u go to display - screen resolution and switch between 720,1080 or qhd+.
But the OP never asked if changing resolution was possible. He most know that we can already change res in the setting. What he is asking is HOW does lowering resolution works.
Im not sure about this but from tv or any pc monitor u can upscale to max reolution of the monitor or downscale to a lower resolution. The pixel are still on but the screen is not push very hard.
Amoled are very power effecient and this has been discuss in the S8 forum for quite sometimes. After all the testing the xda members have been doing it seems that going from QHD down to 1080(full hd +). Doesnt save that much battery (around 5% better battery)
Actually I'm wondering because on a 1080p TV, when you feed it a 720p video, the TV stays 1080p. The video is just enlarged to fit the 1080p display. On the V30 I'm under the impression that the display will actually change. Kinda like having a 3 displays in 1...

U wont see a smaller screen. The screen will stretch out edge to edge but it will look very blurry if u do 720p. Not so much in 1080p mode. So u can say that the software upcales lower resolution. Just like riptide 2 which u can lower or max res in the setting of the game.
Wait, so the software downscales? You sure? Just Android or all apps too? I don't think so. How could software down scaling effect battery life?

The screen is cap at 60 hz. Let say u are playing a game ( this goes with the ui smoothness aswell). Since the screen is cap at 60hz means that the fps is up to 60fps max/cap At 1080p is you play a game that can reach 80fps(cause is not pushing QHD pixel) the cpu/gpu doesnt have to work has hard. So instead of doing 80fps it only have to do 60fps meaning that cpu/gpu doesnt have to work 100% since is able to maintain easily the frame per second require from the 60hz screen.
This is why the new RAZER phone with 120hz screen can do 120fps.
Now if u increase the screen to qhd (1440p+). The same game with higher resolution the frame rate will be much lower. Now. The game probably is reaching 55fps instead of 80fps max (is an example). The screen is 60hz (60fps). So the cpu/gpu is gonna be working 100%. Much harder cause is trying to reach 60fps but it cant. Which equals more power comsuption, hotter device and also cpu/gpu throlling cause of the heat.
I was just wondering what display settings does everyone use and how to get the best performance out of the display. If anyone can tell me all the things to turn on and off for getting there, it would be great.
Thanks

I use the best settings possible, what's the point In having a good phone with the best display if you ain't gonna use it
Exactly. When you say best performance, what are you looking for? Higher synthetic benchmark scores to brag to your friends who also don't understand benchmarks, or the best looking display to actually USE the phone?
Do what makes sense for you. I keep mine on HD+ (720 pixels in the short direction) because my eyesight isn't great and I can't tell the difference. Samsung pushes the higher resolution because it looks good on paper (specsmanship), however I am doubtful that most people (even with good eyesight) can tell the difference between FHD (1080) and WQHD (1440) pm this size phone.
Other people don't matter, check for yourself. I would look at straight diagonal lines and text. If it looks jagged, then go to higher resolution. If not then try lower resolution.
There is a small battery gain from using lower resolution. You can see what Samsung thinks the battery gain is by going to the battery power saving screen and note the savings projected in the "apply" button at the bottom. Change the screen resolution and the projected savings in the apply button will change immediately. The change in projected savings between two modes presumably represents the difference in power consumption that Samsung estimates. For me it is rough ballpark 10 minute life saving from 1440 to 1080 and another 10 minute saving from 1080 to 720 (when checked with battery near full)

I agree with you. I believe that's what my original question was. What are the settings which will give me the best display performance?

I was referring to display performance, which includes having the best visually appealing display settings. I do not care about any benchmark scores. I believe most people have stopped caring about that a while back.

Thanks. I do keep my resolution at WQHD at all times. I was wondering about all the other settings such as Settings -> Device Maintenance -> Performance Mode -> High Performance (I've heard this is needed to get the best display) and other things such as what screen mode looks the best and most saturated (Adaptive, AMOLED cinema, AMOLED photo, etc.) or if there are any other settings.
Guys what settings you keep in adaptive display?
The difference between HD and wqhd is easily noticeable, I have mine on mac settings and the screen is stunning

I was wondering, what resolution are you using?
I've started with WQHD+ and moved to smart, since i didn't noticed much difference(didn't really test battery life, just DPI and fonts).
What resolution do you use, and why?
I've always left it on smart resolution. Never found a reason to change to a specific option.
Im running it on FHD.
Couldn't notice the difference.
