Hello everyone.
I have a Samsung Galaxy S9 and when I try to screen mirroring the phone to a 16:9 tv, using a HDMI cable or through wifi using Chromecast, I have black bars on the top and on the bottom of the 16:9 screen since the screen aspect ratio of the phone is 18:5,9.
If I use the Smart View feature of phone to do screen mirroring, the app has a floating button where I can change settings of phone to customize the mirroring, including change aspect ratio of the phone screen to 16:9 to best fit on the TV screen without black bars.
See images attached. Only in Portuguese Brasil (sorry).
My phone is not rooted so I think it is possible to develop an App that changes aspect ratio of phone without root (at least on Samsung devices).
To help developing, I extracted Samsung Smart View apk of my phone to help on knowledge of the function used to change aspect ratio included in App.

I am developing an application that contains stock wallpapers of almost all Android smartphones brands.
The problem is that i can't deal with the resolution of images. Let's take an example: i have an image with dimensions 1920x1280
I know that the best image resolution for an Android home screen wallpaper is 2x of screen width (for example width of s2 is 480x2=960px) and exactly same height (for example s2 height is 800px) so the right wallpaper size for galaxy s2 (with screen resolution 480x800px) will be 960x800px. But on the market there are plenty of smartphones as well as different screen resolutions.
I am asking if is there any "universal" resolution (i know that this does not exist but at least approximately) for the wallpaper so that to fit on most of screen resolutions ? If there is not this means that i have to crop every wallpaper and resize to the right resolution for most of smart phones screen ?
Any suggest will help me, please give me something like referent, any other app, or any Java code so i can put into my app.
Thanks
Hey!
I received my tabpro and i notice so much lag in games like simpsons tapped out. My girlfriend has Tab 3 and it runns perfectly. Is it about the resolutions, since i have 2560x1600. Is there any way to lower my resolution or do I have to install custom ROM.
And why my homescreen resolution is not that 2560x1600. My image is 2560x1600 and it looks nice in gallery but after i use it as my wallpaper on homescreen it gets blurry.
I thought this tablet is powerfull in games and so on. But i am very disappointed. All help is needed so help me to to get clean rom or just help to lower my resolutions.
Any suggestions?
I'd like to know this aswell.

It should be possible to change the resolution of an app with "app settings", an XPosed Framework module. (root required)
When you set an image as your wallpaper it gets zoomed in (as it has to fit screen and scroll horizontal), therfore, the pixels of the image won't match pixels on the screen anymore and get re-calculated, making the picture blurry.

You found an application to change the resolution? Give us some more information to work with mate.

I want to watch YouTube videos from my 18.5:9 phone on my 16:9 (non-smart) TV. When I connect the phone with a standard USB-C to HDMI adapter, it mirrors the screen on the external display, but it zooms out so that the 18.5:9 aspect ratio is preserved, with black bars on the sides (portrait) or top and bottom (landscape) filling the empty space. When I watch a video in full screen on YouTube, the screen is still mirrored in the 18.5:9 ratio. When it's in landscape, that means there are black bars on the sides on the phone's display (because 18.5 is "wider" than 16), but on the external display, it means there are black bars on ALL sides!
Is there a way to either...
Make YouTube zoom onto the video so that it actually fills the 16:9 display properly...
or...
Make the S9 (presumably S8 is the same) output its display as 16:9 natively? EDIT: to clarify, can you force it to crop down to 16:9 on the actual internal display, so that when it mirrors to the external display, they're both in 16:9?
As one possible example of this working properly, VLC will automatically go into some sort of screen-casting mode when connected via HDMI, where the phone's built-in display only shows playback controls, while the external display shows the video, properly fit to the external display with no apparent cropping or zooming. (when the source video is 16:9, at least!)
Tried using YouTube Vanced instead of the original YT app?

Didn't work, unfortunately.
There are settings to ignore screen resolution in Vanced
Those just seem to allow the phone to output higher resolutions than the internal display is capable of; it doesn't actually change the aspect ratio of the output display...
Hello xda members!
I need to have different screen ratio (16:9) working on an app. It's because some apps aren't very compatibile with 18:9 screen ratio (image is displayed on whole lcd but it's stretched a little or very blurry). Is there any app that changes the resolution or ratio in a specific app? I know I'll have a black bars on the sides, when I'll change it to 16:9. Btw I'm using HavocOS.
As we all know this phone has an aspect ratio of 2.22:1 and we can't watch in this full resolution because most videos and ganes are in 16:9 ratio and some in 2:1 which leaves some black bars on the ends. What I would like to ask is if there is anyway we could fully utilise the display and watch or play in the entire screen resolution or in the 2.22:1 ratio. Edit viewing ratio manually in youtube netflix etc.. and some games
Well what I do sometimes is expand it manually on my N10+.
With different aspect ratios sometimes you need to adapt. At least use a browser that keeps the end bars black. The Samsung browser is my primary vid viewer.
