A1-840HD with a A1-840FHD diaplay, how to get the device use the full resolution? - Acer Iconia One 8

Hi!, i transplanted a fhd model display to a hd model, and it does show image, but doesnt utilize all the diplay area, using wm size/density/overscan, only causes the image to adjust in the part of the display that already is used but not the rest.
Is there a way to make this work?

Would the Captivate video out work okay on a 7" 234x480 screen?

Im thinking about adding a 7" lcd screen to my truck to act as a backup monitor and a larger lcd for GPS. I'd like to connect my Captivate to the lcd and using it for larger, set top viewing of the gps.
Would this work fine in terms of using the video out for gps only? http://www.ecbuys.com/car-lcd-and-c...-tft-lcd-car-headrest-color-monitor-p-52.html

Standard TV video - is 480 lines of resolution - so anything that can emulate a tv monitor (it has TV video in) should display fine. You will get the entire Captivate desktop on your TV - every move to every app is shown - just like having a bigger phone - but you have to touch the smaller screen.

Perfect that is what I need. I will be using the larger screen just to view the GPS and view the video player. I have microsoft sync in my truck and it streams bluetooth audio superbly, but it doesnt show who the artists is on the radio screen. So having a larger lcd on the dash for viewing song info/google navigator, pandora, and using for a backup camera would be great. I did a mockup of how big it would be and where I would put it here:

I think this would be a pretty sweet setup!
one thing to keep in mind - you will want some type of rotation lock feature - this is built in to 2.2. The autorotate is copied to the external screen, so portrait mode on the phone will give you black bars left and right on the right on the screen. You will probably want to lock the screen in landscape mode when connected to your monitor.
Ah yes I am running Cognition Beta 2.2. so I have the option. Good point

Technically, you can change the screen resolution when you install custom ROM (or root it), but you probably won't get rid of the black borders, as the TF701 is a 16:10 device and your screen is only 16:9.

thinking about buying the galaxy tab s2, but...

before i buy this tablet, i need to know if it is possible to change the screen format from the stock 4:3 to the more useful 16:9 in a custom rom or kernel or whatever? i didn't see this asked anywhere, and it is black friday, so i need to find out quickly as i need to make a buying decision. thanks for any help!

What do you mean change it? It's physically and natively a 4:3 tablet.
However you can use the tablet in which ever orientation you please.
If you turn it 90 degrees to landscape mode it becomes a 16:9 tablet, but you can t physically move the buttons.
You're better off buying the tab S if you want native 16:9.

what i mean, is like on a computer, you can change formats of videos or games or what not, from 4:3 to 16:9, so you don't have the large black bars on the screen while viewing one of them.
Er?? Then you either have a totally distorted picture (all things are too high in relation to their width), or you must crop the left and right sides to fit the picture into the 4:3 screen.
If that is what you want... but it is not very reasonable to want it...

What you ask doesn't make sense, you can't physically alter the ratio of something without distorting the image or cutting part of it off.. If a video is 16:9 it must be played back at 16:9 regardless of the physical dimensions of the device.
If you don't like black bars then you would have to use a player such as mx player that allows the image to be stretched to full screen.

You can't not even a computer in proper look. From 4:3 ratio resolution to 16:9 ratio resolution will make everything look stretching and distorted.

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.

[Question] Pixel 5 screen resolution change fix?

Hi guys,
I used to use this method with mostly all of my devices in the past: LG G3, Galaxy S5, Amazon Kindle Fire tablets (including 8'' and 10''). All of them work just fine. But not this Pixel5!
Using the "adb shell wm size" command. I changes the screen resolution of my devices down a notch, for example from 1440p to 1080p, or 1080p to 800p and so on. Then I adjust the density accordingly. They all turn out the Ok-ish screen resolution and have a much better GPU performance for gaming.
My current S10 has the native changing resolution from Samsung, So I don't use it for my S10.
But with the Pixel 5, there is a problem. The camera cut - out on the screen become so weird and placed on the off center position, and the Pixel 5 is unusable
I really love to use my pixel 5 at 720p or 900p, and I believe the Adreno 620 (snapdragon 765G) on the Pixel 5 will handle game at the lower resolution much much better.
Does anyone have a fix for this? please help!
Thank you for your reading!
P.S: OMG, this was my bad for posting the thread into the wrong sub-forum. It was on the other tab of my web-browser. Thank you very much for moving it to the right place, Moderator!!
Why are you not changing the resolution in the settings like you do on the Samsung? A quick search suggest the Pixel 5 has such an option. You're best doing it the official way to guarantee everything will work correctly.
Because you're changing the resolution and DPI through what is basically a developer option, I think whatever is handling the camera cutout (An app? The WM? Android?) is not updating its position and that causes it to be misplaced. Therefore, I dont think you find a simple fix for this. Sorry.

You must be mistaken the Pixel 5 with other phones, since we don't have the option for such a changing the resolution in the settings.
If you mean the display size? It's just a density change, not the resolution.
Thank you for your contribution anyway!
Hi, have you sovled the problem? I encountered a similar condition.
