Question Screen casting a specific resolution/aspect ratio - General Questions and Answers

I want to screen cast my phone to my tv because my tv doesn't have the discovery plus app.
I can cast my phone no problem but there are black bars on both sides of the picture on the tv. I'm assuming this may be because of a resolution or aspect ratio mismatch between my phone and my tv.
It's there a way to cast to my tv where the image fills the entire screen?
My device is a OnePlus 7 pro

Disable Overscan on your TV box.

change your tv aspect ratio to wide mode or zoom mode whatever you call that thing

The oneplus 7 pro is 19.5 x 9 I'm "casting" using the "Screen Cast" icon in the notification tray. miracast or bubbleunp (not sure which tbh, its an LG tv).
Changing the aspect ratio on the tv doesnt work. I need a phone based solution. I need to be able to just send a 16x9 signal.
When I watch 16x9 content on my phone, there are black bars on the left and right because my phone resolution is 19.5x9 and so im projecting that to a 16x9 screen, its literally casting my whole screen.
@jwoegerbauer I have no such option when casting video from my phone. It's stuck at 16x9

[Q] hdmi problem

Hi,
When connecting the asus tranformer, or any other tegra 2 tablet, to the tv I get a wrong resolution.
What happens is that for the 16:9 ratio it cuts about 5% of all the borders of the image. If then I switch on the tv setting from 16:9 to fit screen it works well and I can see the whole tablet screen.
But some tvs don't have that option, and thus the image shows incorrectly cutting a part of the border of the image.
Do you have the same problem? Is there a fix?

Is there a way to have 16:9 aspect ratio via HDMI?

hi,
It doesn't look good on normal 16:9 external display as 2 black bars on top and bottom.
is there a way to change android resolution to match 16:9 ratio?
I'm ok to have black side bars on phone landscape mode, while output correct 16:9 by type-c to HDMI
tnx

No but you can change the aspect ratio on the tv/monitor so that uses all the available screen

If you download this app: https://play.google.com/store/apps/details?id=com.nomone.resolution_changer and grant root permissions, you can change the phone resolution. Set it to 1920x1080 any other 16:9 ratio which is less than the op7p Res. You will then get black bars on the phone, but you will be able to have a full 16:9 experience on your TV / monitor! Have fun!

There is a paid app that I use which works properly. I use it on my 7 pro. https://play.google.com/store/apps/details?id=com.lugalabs.resolutionchanger
I found this free app that works
https://play.google.com/store/apps/details?id=com.iutilities.screen_resolution
now I need programmatically disable and enable soft keys

Anything in Android that can change the active area mapping of my OTG tablet?

I have a OP6 and I found an XP-Pen drawing tablet that I can use with Android via an OTG adapter.
It works, but the problem is, the active area is a 16:9 ratio, while the OP6 is 19:9. So anything I draw on the tablet ends up a little squished or stretched.
I was wondering if there's an Android utility that can alter how much of the tablet can be used at one time, and fit it into a 19:9 ratio probably, with a margin of the active area disabled.

NO FULL SCREEN VIDEO - Amazon Prime - Other

Dears,
I'm getting an issue related to videos. When I try to watch a movie, normally with Amazon Prime ( but also with Netflix even with the setting 'play in fullscreen' enabled ), my phone continue to show 2 black bars on left and right side. And the video of course is not shown in a complete full screen mode... On Prime, I try the 'zoom' option but faces of actors have been cutted often.
I can't understand why and what to do. Of course the setting 'fullscreen' is enabled for every video app in the app settings.
Someone has got my same issue ?
- dimensions of PocoX3 screen are 2400x1080 pixels
- fullHD video has 1920x1080 pixels (16:9 aspect)
- if you want to see your video in 1:1 you will have 240 pixels wide black bars on either side of your phone screen in landscape mode
- if you zoom your video you'll loose black bars but your video will be crop on top and bottom, exactly as you described
- completely normal
- if you can live with distorted image, you can with some video players stretch (or fill) you screen in a way no part of video will be cut off (as I do not use amazon nor netlix not sure their players can do this)
