change resolution with rom toolbox? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

So there's a setting inside ROM toolbox under build.prop tweaks. It let's you choose the resolution of the device. So this got me wondering if you can actually change the resolution of a phone or is the resolution of a device a limitation of the phone's screen. I know on computer monitors its really easy to alter the resolution and wasn't sure if a mobile device could function the same way. I tried changing the resolution from 720*1280 to 768*1280. It didn't brick my device but I'm not sure if it actually did anything.
Can anyone shed some light on this?

I don't think you can change the resolution
You can change the DPI but that's about it

LCD Density Changer?

Has anyone been able to get any density changer apps working on their Nitro HD? I've tried all of the following, and none seem to work. It's possible there is a problem with my su access, so if anyone HAS gotten any of these to work, please let me know. That at least tells me I definitely have an su problem...
DPI Changer
LCD Resolution
LCDDensity
Root Tools
Never mind; my build.prop file was set to read only.
Excuse my ignorance, but what exactly are they for? Does the density changes only the size of text or everything including graphic become bigger/smaller?

For the most part, yes. Decreasing the LCD Density is like increasing your desktop's resolution. Icons and text become smaller, though apps that are written to scale to any resolution will usually appear the same.
Hmmm...I do see some issues with current density, for instance the avatars in Talk don't stretch to fit the square.
So witch tool would you suggest?
I tried DPI Changer the other and couldn't get it to work, thanks for the heads-up about the build.prop!
The Nitro also already has the "Screen Optimization" util (Settings > Display > Screen Optimization) that resizes checked apps to the Nitro's display. It helped with a few games, but some games just won't work (like Asphalt 5)...But now with the Density changer, maybe I'll give it another try.

Actually, I'm not sure any of the tools above would work; part of the problem I am sure is that the build.prop file was not only read only, but there wasn't an entry for the LCD Density - so if the apps work by simply retrieving and editing the property, they aren't going to work. I just edited the file directly with a text editor, saved, and restarted the phone. Some of the apps would then at least report the new value, but still didn't seem to successfully update it. I quit looking because I got the density I wanted (about 270, down from the native 320).
As for compatibility with other apps, if they don't quite look correct it is because they aren't written well, and a different density changing app isn't going to do you any good. Again, it's like changing the resolution on your computer - it doesn't matter how you change your resolution - once it's set it is what it is, and apps that don't accommodate it just aren't going to look good.

The Screen Optimization utility only seems to address apps that are written to a specific resolution - not pixel density. In this sense, the LCD Density is actually more like changing your computer's DPI - I didn't use that analogy first because more people are more familiar with changing a desktop's resolution. The fact is that LCD screens have a set resolution, and you cannot increase or decrease that resolution through software. The Nitro's extremely high resolution (1280x720) just isn't common enough in phones (most software would see it as a tablet) to be accounted for in all apps - particularly older ones. So, the screen optimization app that is built-in will automatically stretch apps to take up the entire 1280x720 pixels, even if the app only renders (for instance) 800x480 pixels .

Can't adjust resolution, please help

Hello everyone,
I am trying to use an app to adjust the resolution (or DPI) to simulate a 720p screen. However, my phone simply will not change its resolution no matter what I do. I have used the app "LCD Resolution" as well as another similar app. What I have done is to change the dpi setting in the app from 240 to 160. Then I click apply and it says I need to reboot. After reboot however, the setting has been reset to 240 again.
Can anyone tell me how to simulate a 720p screen on the Epic 4g Touch? I am using the CyanogenMod alpha 4 and I want to get as close to the experience of a Galaxy Nexus or Galaxy S3 as possible.
Could someone please help me?
Thanks so much.
Try Rom Toolbox in the market, I believe that's what most people here are using. Should be under build.prop tweaks set it to 160 and reboot.

If you have the root explorer app you can go to the build.prop located in system yourself and change the lcd density value yourself (you have to scroll down a bit). Make sure you mount as Read/Write so you actually change it instead of just viewing it.
Also a side note, you're not changing the resolution, only the density of the pixels packed. The resolution can't be changed on this device, nor any of the current Android devices for that matter.
The only one that worked for me was lcd resolution (root), by wemobs labs. I tried a few others, but they didn't change anything.

[Q] Adjusting DPI on rooted N7?

Quick question all - On all of my android devices in the past I have used build.prop editor once rooted to adjust the DPI down to increase screen real estate. This would be particularly useful on the N7 to put it in tablet mode. However, when i adjust the density parameter downward and reboot the device, nothing happens and the value resets to default. Does anyone have any thoughts on how to fix this? Thanks!
Sorry to bump this ... anyone have any thoughts?
I changed using esfile explorer text editor. Did not get in tablet mode but did change the density.
ro.sf.lcd_density=320 was the line I modified.

I also use Es File Explorer to change the screen density. You have to make sure the /system is mounted as R/W. I'm running at 240dpi and like it much better than the stock 320dpi.
idk if this is related, but I heard from a guy at work that you can increase the resolution from the stock settings? not sure if I believe him, he was saying something like 4k resolution, which just sounds odd since why wouldn't they set it to that by default then.
Yes! it worked. Probably because i wasnt r/w. Thanks very much guys

What dpi are you running?

I was wondering what dpi everybody is running. Currently I am running stock but was wondering if there is a good dpi level everybody is using that gives more space and does not cause force closes.

400. No problems with FC on any DPI in the past.
However it does mess with a lot of apps. To fix this you need the Xposed framework and an app called App Settings.
I've dialed it down to 320, sure makes things TINY but love the extra real estate. 480 on this phone is huge, reminds me of the folks running 800x600 on 21" monitors!

400 sounds pretty high to me. i haven't rooted my N3 yet so i cant change my DPI but on my N2 i was running 280 and it seemed perfect to me. Thats what ill use on my N3
320, and I think it makes things look normal. I put it at 220 in per-app DPI and that was tiny. 320 on the Note 3 is comparable to 220 on the Note 1 which was what I always set my Note 1 to (ran it at 200 for a while even to get the Nexus 7 style tablet UI). I use per-app DPI to set the dialer and camera and other Samsung apps back to stock since they get distorted at 320dpi.
Edit: You realize the N1/N2 and N3 are not comparable in dpi right? The increased resolution means to get N2 280dpi you'll likely need 380-400. 280dpi on N3 is getting pretty small. N1 220 compares roughly to N3 320.

It's a 1080 display, 320 is definitely the lowest I'd go!
280 would definitely be small.
320 on 720 devices such as the Note II look about the same as 480 on the Note 3, in my experience.
Nice thing is it's easy to change in build.prop.
I like 360. Its a nice round number... Puns aside, I really do like this dpi.
That or 380

Thanks for the replies. Okay so if I set it somewhere around 360 to 400 I will have no problems with system ui only apps that I will have to adjust with app settings module? Would I have to go into each one and adjust or adjust all at once. I have a lot of apps. Also what is the stock dpi set at? To change it I would edit it under build prop using rom toolbox?
Was wondering if you guys could post screen shots to get a better idea.

If you use app settings you can fix issues with programs not displaying correctly OR just looking too small...
Default is 480 in build.prop.
I use root explorer, open the system folder R/W and click and hold build.prop and select open with, text editor. Make changes and it will save original as build.prop.bak. Reboot to see changes.
I can post a screen shot of the settings used in app settings. Once you get the hang of this you can adjust as you wish. With some apps I prefer to use a slightly different DPI in app settings so it's not as big as it would appear at 480 yet not as tiny as it would appear at 320. That's the nice thing as you can pick anywhere in between for a balance that suits your needs/wants.
Furthermore, all these settings will be saved/backed up if you use Titantium Backup to back up your device. That's a good thing if you're a flashaholic like I tend to be!

Globally I use default settings but I like to adjust the dpi for certain apps using App Settings. For example, for some apps I like a tablet look to them which can be achieved sometimes. Notablly this can be done with gmail app. In this case I set dpi to 320 and screen dp to 800x1280. Here is a screen shot. Maybe not for everybody but I like it.
I personally use 400 for most apps except for media player style apps as the large button interfaces help for use on the go.
That said, do you guys have issues with the gallery photo editor app and other apps that display pictures using stock libraries (or so I'm guessing) where the picture is zoomed and cropped where you cannot see the whole pic even if you try to zoom out?
So far the google gallery photo editor, the samsung photo editor and ES file explorer all have the same problem for all DPIs other than 480 applied globally or specifically to "Android System".
Even if I set the photo editors to 480, as long as the "Android System" package is not 480 the pictures will be cropped.
Thanks

How did you change your dp (i assume that's the resolution) to 800x1200? I already did the global DPI change to 400, but I want to see how that resolution looks for myself.

Hi. I'm just using the xposed module called App Settings. In the screen shot you can see where I change the dpi for the gmail app and the screen dp. There are a set of dp you choose from. Some make a difference and other settings don't seem to have an effect. Might want to do a back up before trying. Sometimes a bad selection can cause problems when booting up. Hope it works out!
I run almost everything at 340, as 320 is just a little too small for me. For the Samsung apps (that I haven't removed), I either use ones modded for multi-dpi from the International Note 3, or ones that I have modded myself, at 320. I don't think I have anything that still runs at the stock 480. Having a screen this size, but with everything blown up that large just seems like an incredibly bad utilization of space to me...

does anyone know how to make it so that your keyboard won't shrink? I use SwiftKey and though you can make it bigger it's not big enough and of you try using app settings it messes with it and turns out all bonky. I want to go down to something like 400 but the keyboard gets a tad small.

New dpi via adb?

Hi
I'm trying to change dpi in adb. Adb finds the device but when I'm typing "adb shell wm density 380" it doesn't work.
Anyone knows why?
Thx in advance
Try going into developer options and enable the security setting to on.

I think Xiaomi controlled the dpi using another variable, its called persistent density or something like that.. hence changing the normal density variable wont have any impact

Are USB debugging & USB debugging (Security settings) both enabled?
If I recall correctly, enabling USB debugging (Security settings) is a bit tricky.
https://forum.xda-developers.com/mi-mix-2/how-to/guide-changing-min-width-dpi-miui-9-t3736218
this can be helpful for you. My dpi is now 290. If you go higher google keyboard change tablet mode.
I was able to change it using Activity Launcher using the tutorial below:
http://en.miui.com/thread-1093064-1-1.html
Default dpi is huge even at the smallest setting. I am using 320 and it's perfect, can see a lot of content without being too small
Just make sure Developer options has USB debugging (Security settings) enabled and use adb shell wm density 320
Big difference. Would be a waste to not see more content on such a big screen but also understand some people's eye sight may not be as good so they prefer bigger objects
320 vs Small setting
I used this tool to change dpi:

tried this. but it doesnt seem to work. none of the layout is changing.
yup changing dpi without root is tricky. u need to enable security usb debugging. u need to use vpn apps.
got usb debugging on.
whats vpn tools?
anyway guys, thanks much. yea i have noticed that there are two options for usb debugging. look passed the other one.
now its working.
I just upgraded from Max 2 to Max 3... LOVE that i can change the DPI without rooting... had no trouble with either phone doing this. With the Max 2 i had it at 360, but with the Max 3 i'm trying 290....i may go up to 320 just because i need my glasses to see things like the battery % lol . No clue why Xiaomi didn't drop it below 400 out of the box but thrilled i can do it easily.

I use Font size 80%, Display size Custom (289), Smallest width 597 dp.
597 or 289dpi is the smallest dpi you can set before tablet mode is enabled in portrait mode.
If you rotate your phone watching a youtube video in full screen tablet mode is already enabled so the notification drawer is opened by swiping down on the left half side of the screen otherwise nothing will happen.
Setting Smallest width value is the easiest way to change dpi in the latest android versions.
Setting it to 596, 598 and 599 won't do anything.
It will either default back down to 595 or jump to 600 because it must represent a whole number in dpi.
It is crazy that pretty much ALL phones comes pre-configured out of the box at factory state with a dpi so large you can barely fit two words across the screen..really...I don't think anyone have this bad eyesight, if so then you need to get new glasses or lenses.
There are high index lenses out there that go to 1.9 and even beyond 2 if you really want to pay a lot if your prescription is crazy high to be able to enjoy a thin and light pair of glasses.
Like what is the purpose of getting a phone this big if you gonna have it display just as little as your old phone with third the screen size..isn't that why you wanted a bigger phone in the first place to get more screen estate, at least that's what I wanted..

I can't agree with you more. Just thankful it's so easy to change
On a side note...and i'm not sure it's related because I didnt' try before changing the dpi(i use the adb method)... my TSN app won't stream any channels. It gives me an error... i'm not sure if that's the DPI setting that caused it? Only app that doesn't work right. I'm going to have to play with that when i'm home from work as it worked on my Max 2 set at 360 no problems and the only main difference i can tell with the 2 phones is the version of Android.
Edit: nevermind it wasn't the DPI setting... i allowed TSN GO to work in full screen mode and that did it.
Love the phone!
