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 .
hi
this guide shows how to change the default display resolution on the htc10 (should work on other devices too).
this affects all the apps too of course. the changes are applied in runtime so you can check the effect directly.
some system apps like keyboards might require a soft-reboot (restart systemui) for changes to apply.
the way sony is dealing with 4k displays and the way samsung allows this in settings inspired me to write this guide.
root-access is not needed for this. only enabling usb-debugging in developer settings is needed.
the goal of this guide is to reduce battery consumption by reducing the amount of virtual pixels being diplayed.
warning: i can not be held responsible for any damage this mod might cause to your device or data. on your own risk.
guides how to enable developer options and adb debugging can easily be found on xda.

requirements:
htc 10 device
a computer with adb folder
connected usb-cable
note:
htc boost app is interfering with this mod.
i recommend to disable all foreground app optimizations in htc boost app.
otherwise, all the apps interface will be too small when reducing screen resolution.
note2:
in android 7 nougat, google added the display-option to reduce display size in addition to fontsize.
this option is also directly interfering with this mod since it represents the wm override density value (see below).
value descriptions:
wm size - physical size: 1440x2560 (that's our native display resolution)
wm size - override size: value is not present in stock rom (android ui is running with physical display resolution)
wm density - physical density: 640 (that's our native virtual display density)
wm density - override density: value is not present until you change display size in settings (640 is used)
when changing display size in settings to "small", override density value is 544.
when changing display size in settings to "big", override density value is 720.
lineage os 14.1 has more options for override display density value: 448/512/576/640/720 (as reference).
the default android density values are: 240(HDPI)/280/320/360(XHDPI)/400/440/480(XXHDPI)/520/560/600/640(XXXHDPI)/680/720)
wm density things change, when changing wm size.
overriding physical density value is reducing the size of all elements on screen,
maybe changes the grid size on homescreen (launcher) and it might add additional options for rows/columns in appdrawer.
some comparisons with other devices values:
htc one m7/m8 (4.7/5inch, 1080p)
wm size - physical size: 1080x1920
wm density - physical density: 480
htc one max (6inch, 1080p)
wm size - physical size: 1080x1920
wm density - physical density: 400
htc u11 (5.5inch, 1440p)
wm size - physical size: 1440x2560
wm density - physical density: 640
nokia 8 (5.3inch, 1440p)
wm size - physical size: 1440x2560
wm density - physical density: 560
google pixel (5inch, 1080p)
wm size - physical size: 1080x1920
wm density - physical density: 420
google pixel XL (5.5inch, 1440p)
wm size - physical size: 1440x2560
wm density - physical density: 560
xperia xz premium (5.5inch, 2160P/4K)
wm size - physical size: 1080x1920
wm density - physical density: 403
note: see how they deal with 2160x3840 display? phone is running only 1080p exept in specific apps.
that's what we want too to save battery.
downside is that we can't use full-res of display anywhere anymore (exept for VR, 1080P should be sufficient though).
first we want to override the physical display size from 1440x2560 to 1080x1920.
the adb command to do so is: "wm size 1080x1920"
second we want to override the display density value from 640 to 480 (i would even recommend 420 or 400).
the adb command to do so is: "wm density 400"
feel free to experiment with this density value and post your results.
when going lower than value of 436, sense launcher changes from 4x4 to 5x5 grid-layout (when 1080p is set as res).
when going lower than value of 370, htc sense keyboard (sense 7) switches to small mode (when 1080p is set as res).
when going lower than value of 289, systemui switches to tablet mode (when 1080p is set as res).
known issues:
-htc bootsplash of the htc10 is made in 1440x2560 so the logo is shifted to the lower right (who cares)
-signal bars are crippled
-navigation bar sometimes shows wrong button-orientation with custom density values
-some apps might show ui scaling problems with custom density values
-htc lockscreen pin entry screen breaks when density value is too low (use aosp lockscreen as alternative)
return both values to default with the following commands:
wm size reset
wm density reset
if you just want to make items smaller but running at native display res (no battery optimization):
wm size - physical size: 1440x2560 (leave this value as it is or revert it with the command above)
wm density: try the override values mentioned above and see how it behaves.
when going lower than value of 581, sense launcher changes from 4x4 to 5x5 grid-layout (when 1440p is set as res).
when going lower than value of 490, htc sense keyboard (sense 7) switches to small mode (when 1440p is set as res).
when going lower than value of 385, systemui switches to tablet mode (when 1440p is set as res).
please report back about problems or battery consumption improvements.

Does density effect power consumption when size is set to 1080x1920?
I set it to 420. Lower or higher,are there any differences?
Edit : What is the perfect match for the 1440x2560 size 544 density in 1080x1920 size?
density should not affect battery consumption. only the virtual display resolution.
the calculated values are:
1440x2560->544(small)/640(default)/720(big)
1080x1920->408(small)/480(default)/540(big)
i will have a closer look at how samsung does it on the s8. there is also a setting for only hd resolution.

I use Viper10 5.11.0 for HTC 10. Current resolution is 720x1280 with DPI 272. It is running ultra smooth and perfect. Only problem is the last apps screen previews does not fit the window. It is like %400 zoomed.
anyone still doing this? Does setting to 1080*1920 with 480ppi improve battery life?
Nooe, it doesn't

Nope. Some apps have some troubles. I revert the settings to original and just using the HTC Boost+ app to run apps in 1080p. I can't see any difference between 1080p and 2K about the battery life.
1440p vs 1080p
Hello guys. First of all, great thanks to HD2Owner, who made this feature(we better say MOD) possible.
Recorded my results firstly with 1440p(native), I have stock ROM, kernel and bootloader. Tried to do almost the same scenario.
2 results from 1440p:
4h 30m
5h 17m
Then i switched resolution to 1080p, Open Apps zooms automatically(looks strange, the same as above in some pictures), boot logo does not show up to all screen and lots of these kind of insignificant bugs.
2 results from 1080p and scenario:
4h 41m
4h 40m
So, I guess you cannot say that there is a difference in battery life for sure. But I noticed that small fonts become a little bit shrunken, if I can use this word, less crisper. When you read or browse websites, you definitely notice it.
Nevertheless, HD2Owner, thank you for this making this experiment and experience possible and I will go back to 1440p.
For gamers this trick is godly ! I use 1280x720 resolution and 280 dpi and it is great for gaming performance! My HTC 10 is now lightning fast ,
I also read that , 720 resolution scales pixel by pixel on the screen because 1280x720 x4 pixels is exactly 2560x1440 ,but 1080p 1440p is 1.777x so it does not scale pixel by pixel.
Steps :
1. Download any terminal emulator .
(you'll need root permissions)
2. on command prompt type following commands :
# su
# wm density 320
# wm size 720x1280
( After each command press enter )
Note : you can change software density ( display size / smallest width ) from settings . Set it according to your preference . ( Second command set default . )
For hd use density 320 size 720x1280 .
For full-hd use density 443 size 1080x1920 .
For quad-hd use density 548 size 1440x2560 .
how does this work, where will the excess pixels go if our screen is 1080p?
and what are the benefits?

It cant change your display lcd ppi as it is hardware default , but it changes the display resolution like we do for dpi in settings .
Only a tweak . But this will show your display resolution changed in system diagnosis. ( DPI )
Screens
Do you notice any difference from FullHD to Quad-HD? Does the image quality look better?

It is difficult to observe , but yes , slightly . But at d same time , load on cpu increased a bit , smoothness of ROM affected .
Switching to HD smoothened ROM a bit but at d cost of image quality .
Anyone must try
8k resolution ??
7840×4320
thanks ! I've been trying for ages to use 720p resolution on this phone to improve battery life and no app on play store was working fine. Even if picture is not as crispy, it is okay enough for every day use.
There is an easier way to do the same modification.
Download Easy DPI Changer, through Play Store.
Is there any way to change the resolution of the screen from Full HD to just HD to decrease battery drain?
Please test :
from PC with adb.exe
adb shell wm size 720х1520
and next command
adb shell wm density 320
To revert :
adb shell wm size 1080х2280
adb shell wm density 480

It has a problem. When change resolution battery percentage and other icons appear behind notch and how i fix it.
Also it has screenshot problem

Try with resolution 840x1600 and density 320, you will have a less tall screen (it hides notch)

Hi all,
Is there a real autonomy benefit using lower screen resolution ?
I understand that it's easier/faster/less energizing to render less pixels, but I guess there should be an extra work to adapt high resolution screens to lower display.
So, can someone confirm (and maybe quantify...) the gain in batterie life using lower resolution ?
Thanks in advance :good:
Hello, I have a unit with 800x480 screen which I used to operate in a higher resolution set with Easy DPI. I was on Android 8 with the Hal9k mod. I upgraded to Android 9 (a stock HA rom) and rooted so Easy DPI can operate. Now I can change the resolution (1024x600 and 1280x720 both work) but the touch screen does not work after that (actually the bottom half is not working; I can only work on the upper half of the screen). Has anyone seen this before? Should I change anything else? I let the DPI to the default (240).
Thank you in advance,
A.
