LineageOS 18.1 / how to lower screen resolution / dpi - Samsung Galaxy Note 8 Questions and Answers

So, it seems the default resolution is Quad HD - 2960 x 1440 / 480 dp.
I guess if I want to change the resolution i have to change "smallest dp" in the Dev's options.
I'm not sure how to change it to HD+ ( 1080 x 2220 ) .
How to calculate exactly ?
If I do this, is the battery going to last longer ?
Can you help ? Thanks

Density/DPI change

Hi,
I am new to the p7. I am used from my Samsung and nexus devices to adapt via build.prop DPI in order to see more things on screen.
Build.prop has no DPI setting. How (which app?) Proved to securely change DPI? And what is stock DPI for 1080 and 720p (rog)?
Thanks
No one feeling the need to show more on screen? [emoji22]
Hi,
Have you found a solution for this yet?
I've recently got myself a P7 and I'm trying to get something similar to 240 dpi(like my s3).
People have mentioned ROG tech, but I can't find that option anywhere.
ROG setting is under Settings - Power Saving, then menu (upper right corner) setting.
Rog? I tgought its resolution (I.e HD 720p instead of full HD1080p)? Is there also a setting for density hidden besides ROG?
rog doesnt do the trick
I've activated ROG, but all it does it help the battery to last longer, by reducing performance and screen res.
What I (and op) are looking for, is something to change the dpi (pixel density/LCD density). Like on samsung phones, you can do it through build.prop
No one managed to edit dpi?
Still have a problem...
Where.is the rog option in emui3?
changing dpi on P7 ??? such little screen ?? NO POINT it is tiny already ..

Android 5.1 display density issues with 493 for contact thumb nails and some pictures

I just upgraded from 5.0.1 to 5.1 and I've noticed that when I change my resolution from the factory default of 560 to say the native res of 493, the contact thumb nails are distorted. If I use the terminal command "wm dentity 560" to go BACK to 560, it fixes it. Normally I run 493 which is the native res for this screen.
5.0.1 does not have this issues, only 5.1.. I also tried other resolutions and I get this issue on everything but 560.
I'm using CleanROM 2.2 which is a stock based ROM.
Also I noticed pictures in some image browsing apps do not display correctly. They show as super zoomed in on one section and I an not zoom out. ES File Explorers image app does this but for example QuikPic does not.
If I go back to 5.0.1, all problems solved though.
Just wondering about other 5.1 users experiences with stuff like this.
493 is not the native DPI. PPI and DPI are NOT the same.
Just to echo what @akeller said, DPI is not linked to resolution. DPI is not the same as PPI. PPI (Pixels per Inch) are how many physical pixels are in an inch of your display. This obviously cannot be changed.
Lets say you have a 5" screen at HD resolution (1080p) and also a 10" screen at the same resolution. As you can imagine, you have the exact same amount of pixels on the display, but the display is bigger so the pixels are also bigger.
This means that assets on your screen (icons, buttons etc) will also be much bigger, so you are not taking advantage of a bigger screen as you can only fit the same amount of stuff on it. For this reason, DPI is used as a scaling method to make assets smaller, to fit more on the screen. There is no hard-and-fast rule as to what DPI to use. Generally, the bigger the display, the smaller the DPI should be to make bvetter use of it. OR, the lower the resolution, the smaller the DPI should be. There is no direct link to PPI and DPI.
After you run "wm density 493" also run just "wm density". Now you'll probably see that it reports two values, 560 and 493. The solution is to also edit build.prop (change 560 to 493).

custom resolution on rooted mini

Hello. My displays native is 1360x768 so on mini's default 1280x720 it is not "clear". I have rooted my mini and tried Resolution Changer and similiar apps, but it won't work as i want too - my display still recognize resolution as default 1280x720, even on boot, only DPI changed. I tried to find any resolution keys in config files, but no luck. Does anybody know how to make it? Is this even possible?

As far as I know they only have it set for 1920 or 1280. That being said if you go 1920 and get into the experimental settings it allows you to zoom in from 1920 to ? as it is only listed as 1.25% 1.5% etc. and not actual resolutions.

Weird question about dpi and UI tuner.

I've always used ui tuner, and i've used 289 ppi for more screen estate. But a z3 runs a 1080 screen at 424 ppi. So we know the hardware in the z3c can that. But i can't set my dpi to 424 as it would make everything larger and not smaller. So i have to use negative ppi. So i go from 320 to 289. When i lower the ppi it makes things smaller which also means the hardware has to draw more content.
But how do you figure out the relation between these. How does 289 ppi on 720 resolution relate to 1080 at 424 ppi?
Does this even make sense to you ?
System and apps use both resolution and dpi values to determine screen size, so they can figure out how much space to dedicate for interface stuff (bars, etc).
size (inches) = resolution (pixels) / dpi (pixels / inch) = (resolution / dpi) inches
The bigger the screen size, the more “zoomed out” default/interface view a device usually has.
The pitiful thing with certain world wide web sites is they use this information to determine your screen size and decide zoom level, usually resulting in jackassilly bigass screen items and little onscreen content, sometimes further sabotaged with squatter behemoth search bars and dumbass Twitsh1t and Fakeb00k buttons.
In my honest opinion, this is kind of stupid. I prefer fully zoomed out classic desktop pages, I'll zoom in where required, thanks.
Cheers :laugh:
