[Q] MHL/Miracast 16:9 - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

Hi, I done a few searches for this, but couldn't find an answer. The Note 10.1 2014 along with the Nexus 10 (both 2500x1600) leave borders when connected to a 1080p TV/monitor via HDMI. This (at least to my understanding) is because they are outputting at a ratio of 16:10 where HD is 16:9. Is there a way to solve this without using some sort of zoom/cropping on the TV side? My guess is the only way to get a perfect image is to have the tablet send a 1080p signal and probably create borders on the tablet as they only allow mirroring. On the plus side this would allow them to run smoother as they would be pushing far fewer pixels.
I've not used Miracast, but am assuming it would suffer from the same problem?
Any info/help would be appreciated, thanks!

Trust my brain to kick-in "after" the last moment and think about searching for a resolution changer!
I found this:

I've not read it all, but seems to be what I was looking for although it requires a root which I don't really want to do just yet!

Anyone tested this , or found a non root solution.
I have the same issue with allshare cast

I wouldn't try the resolution changer or script thing if I were you. Apparently it doesn't like our device even when rooted. Someone a while back posted a thread which basically rendered the device useless because of the resolution changer and he had to flash stock firmware again or something to get it back to normal. I have the same issue with the black bars thing when using MHL and I couldn't find a solution for it anywhere for this device.

Thanks C2Q, guest we just have to sit tight and wait for updates. Devices with a resolution of 2500x1600 should be at the top of their lists especially considering the significant performance increases you could expect from dropping the resolution to 1920x1080.

I tried the 1920x1080 and got stuck in a bootloop To fix it I had to use adb pull /data/data/com.android.providers.setting*s/databases/settings.db from TWRP, open the DB in SQLite, remove the 'freeze resolution' entries in the table and push it back. It was a good learning exercise but I don't want to do it again !

Thanks for the warning. That would definitely had been the first thing I would have tried after rooting. I'm sure you've saved few of us.

Multitasking fail

Hi, HTC Sense 4.0 multitask is very bad, i can't use 3 apps in the background at the same time, first i thing it's ICS problem but when i compare it with Galaxy S 3 i find that HTC really need to fix there multitask issue.
Checkout this video i create it:
here's the video link https://www.youtube.com/watch?v=4Sw0ALWKCZ8 i don't know how to embed the video here ><"
Any one here can fix it ?
Is already a well known issue. Somehow people begin accepting it as a feature rather than issue.

Are there any known ways to tweak this behaviour or work around it? I'm finding it very annoying, as I'm using something like PVStar+ to play YouTube in the background (for audio), and suddenly it stops working because the One X has decided to kill it mid song or whatever.
When it starts killing active audio stream, I begin to have problems :-(

The only negatives was smaller benchmark scores, nothing else seemed slow with the multitasking enhacements.
HTC really know how to limit us, s-on crap, this multitasking lack and camera locked to 2MB pics. Fixed 2/3, multitasking and photos just under 8MB for colourful , detailed scenes. And we can install custom roms with a little inconvienence. Almlst 3/3 HTC your practices suck.

UPDATE: 60 fps Achieved!! 4.3

So after a decompile I was sifting through the smali file and noticed something. First, some super odd 3K recording resolution - this is in the file dealing strictly with recording video so no, its not for still captures. Anyone have thoughts/input on this?
Also, we can record at 60 fps in 1080p. Albeit only at 14mbps (yeah, so I'm going to modify that ) but how great is that?! Now people can stop asking for it. Before anyone asks - I have no idea if this carries to 4.4 but I'm sure it does.
If anyone wants proof and doesn't want to decompile the apk on their own - say so here and I'll post the smali.
UPDATE:
Well I did it. Haven't done any extensive testing but I managed to record two videos without any issues. There may be issues so as always - be careful. I tested this on Wicked v10, it should work on any 4.3 TW ROM but only time will tell. I need to add that so far its limited to about 10 seconds. Past that it drops to 30 again, not sure why yet.
This is my modified camera. What does that mean? Recording bit rates are higher (both audio and video, 1080 and 720). Video records at 60 fps (keep reading if you don't know why that matters).
Bit rates:
1080p: 20 mbps @ 60fps
720p: 17 mbps @ 60fps
Audio: 320 kbps @ 48 KHz
For those that don't understand why 60 frames per second matters it really comes down to quality. For analyzing videos, editing them, capturing frames for a still shot, even general viewing. It allows you to slow a video down (same concept as those super slow motion cameras on TV). Videos just seem more fluid overall also, when played at normal speed.
I'm sure someone can elaborate on the above better than myself.
This is just the apk. Not a CWM installer package. So you'll have to install it manually. One you replace the stock SamsungCamera2.apk you'll have to reboot. Please be mindful of how large these video files will get. Let me know if there are any bugs (I'm sure there will be a few).
Here's the link. It's on my Google Drive.
https://drive.google.com/file/d/0Bw3mIOQ0TV63cDJJN0ltdGRXM0k/edit?usp=sharing
So I modded the camera to record 1080p and 720p both at 60fps on the standard settings. Both with higher bit rates for audio and video. So far it installs and works flawless. Can't say much for recording since it's nighttime and I'm not about to disturb my pregnant wife
Will update tomorrow with results. If it all looks good I'll update with a test version in the themes and mods section.

Good, but it didn't get over 31fps so I'm doing some more edits. Hopefully I'll have it pinned down soon and post it for testing.

When you get it working, can you build it into an .apk for those of us that don't use custom recovery? I'm stock 4.3 rooted, but don't want to trip KNOX flag just yet

I can try. I think all you have to do us drop it right into /system/app. Though I think with your type of install it installs that to a different partition and I don't know which one.

I can test it for you on TW4.3.
Still doing some work, just so you know I haven't dropped this.
Also I've found a couple other interesting things while digging around. I don't want anyone to get their hopes up on these two but here they are.
1: In fast mode our rear camera has two options - 60fps and 120fps. The latter is limited to 720p from what I can tell and I'm not sure if anyone would want that. Though on a higher end display (TV or whatever) it might be handy. In the real world though, I have no idea if it would be ok for the camera module. Not to mention the file sizes would kill your memory and battery even if I dropped the bit rate. We'll see I guess - That's what owning Android is about
2: UHD. 'nuff said. I'm having trouble finding the exact 4K resolution listed but UHD is listed in it as an option.
Like I said - don't get your hopes up on those two. They're a bit far fetched, though I know Sammy underused this phones camera. Battery life would be the reason for that.
If anyone with experience writing apps or any devs read this, I would appreciate the help.

Excuse me if I am not overly optimistic...
Usually the development model is working in a logical and chronically method & not backwards.
First you publish out the solution (Application) even if it's not completed & then your advertise it or asking for testing volunteers.
Its not about bring out an idea, it's about making some user excited about it & then tell everyone there are issues, delays...etc.

quite curious as to if the phone can even handle 120fps at 1080p. others have said UHD was not supported due to chipset limitations within the 320 vs the 330 found in int/note 3 which i call bs on. i highly doubt the chips are limited in that way, if anything maybe the native api was removed for the 320 firmwares. as you say UHD is listed... when your done tinkering perhaps you could see if you can force all recording to the external SD as the current setup utilizes the internal sd card for video feeds/burst shots due to the higher bus interface. class 6/extreme sd chips i think can handle 1080 properly at 30fps according to some sites.
nvm my mistake just burst shots are saved to the internal regardless video feed obeys the camera setting.
Any update?

Not yet. I can't get it to work at 60 fps only editing the apk. Not giving up though, I just had to take a break because of no sleep. My pregnant wife keeps me up tossing and turning.
I doubt the kernel is limiting the frame rate, or if that's even something that would be in a kernel. I don't touch those - I think I'm far too green for that and have no idea where I would start.
I'm off today so I'll have a chance to mess around with it some more and hopefully have something for you to test that does more than say "recording failed".

It must be kernel related, I say this because some custom kernels on this very forum can't even handle the slow motion option in the camera. They crash your phone and make it reboot. BUT the stock kernel can do it? So maybe some kernel tweaking will get the fps to 60

Hey, what exactly did you do? I am using the Note3 camera so I don't wanna install the attached apk in the OP. Plus, I could probably turn this into an xposed module for you. Making future mods easier.

I would still stick with the Note 3 camera for now. It's still being very buggy. It looks like there are definitely some other mods that need to be done other than just the apk. I get frame drops in the logs and every now and then it throws and error that "the device might be doing too much" and drops 40+ frames.
Currently all I did to the apk was editing a smali file. Then a couple reboots and let it settle for a few minutes. I just need to figure out the frame drops.

Depends on what method you like. The easiest it to use a file explorer (root explorer or another one). Mount the /system as rw and replace your current samsungcamera2.apk, then change the permissions to rw-r-r. Make sure to backup your current one of course. Also remember, this is for testing so there will be issues. Logs and feedback would be great too.

[Root] [Guide] How to change your Resolution & DPI on AOSP ROMs

* I am not responsible for bricked devices, displays not working, or your phone melting *
Now with that out of the way, hello! Welcome to my first guide-thingy. As it is my first, I apologise if there is a mistake or if I have left something out, but this process is exactly the process I have used.
Recently I've had a few people ask me about changing their phone's resolution and DPI as said in my signature, so I thought I'd write up a guide for people to use! The ROM I've done this on is the BlissPop AOSP ROM but the process should be similar for most if not all other Custom AOSP-Based ROMs. I am UNSURE if this process works on the stock ROM or any stock-based ROMs.
Prerequisites:
- Root access
- Root File Manager & Explorer (Such as Root Browser or ES File Explorer)
* Root Browser: https://tinyurl.com/aytbttu
*ES File Explorer: https://tinyurl.com/cd4u27q
- NOMone Resolution Changer
* https://tinyurl.com/kjg63jn
- OPTIONAL (For Multi-DPI Patch) Latest AROMA (Now known as Open) GApps Package
* http://forum.xda-developers.com/android/software/pa-gapps-continuation-t3098071
Lets get started!
Firstly, the Multi DPI Patch. It's not essential but allows apps to be properly resized to match your custom DPI, and in the latest Google Apps package it has an option when installing to install a multi-DPI patch for people who are using custom resolutions on their phone. Like me, I'm not using 2560x1440 (Stock 1440p resolution) I'm using 1920x1080 (1080p) resolution @ 370 DPI.
Changing your Resolution & DPI
1. Download NoMone Resolution Changer from the Play Store above (It's free) and grant root access
2a. Open a root file manager (Like Root Browser or ES File Explorer (You have to enable root-access for ES) ) and navigate to the /system folder on internal storage. Find your build.prop at the bottom. Now, you're going to want to create a backup of this file before we do anything as it defines how things work on the phone, so create a copy and move it somewhere safe from being wiped (Like an external SD card)
2b. Click on build.prop and open with a root file browser
2c. Find the line under the #ADDITIONAL_BUILD_PROPERTIES section that says ro.sf.lcd_density=xxx and change 560 (default DPI) to something like 430 if you want the font and stuff to stay the same size or 370 to make it smaller and hit save, grant root-save access if required. Then, open the file with another file manager to verify it's saved and changed. Adjust the DPI to something that you like, but be cautious as not all DPIs work properly (I only know of 370 & 430 that have worked for me). This step may vary depending on how your ROM sets out your build.prop.
3. Set your desired resolution in NOMone Resolution Changer (Mine is 1080x1920, remember to do it backwards so 1080x1920 not 1920x1080 otherwise your phone's GUI will be landscape and not portrait, and will go off the screen)
3b. Set your desired DPI to match the DPI you put into your build.prop file and hit apply (Grant root access if requested). The app will apply your settings and change your screen to match the new settings. It will then prompt you if you'd like to keep these settings, hit yes or no. If you hit yes, it will give you an option to change back the settings after a minute so you can see what the phone looks like at that setting.
*This next step only applies if your ROM has an option to manage the DPI setting itself, like BlissPop does, otherwise skip it*
4. After you've applied your custom resolution and DPI, go to Settings (Yes everything will be massive-sized don't worry) -> Display & Lights -> Scroll down to the bottom, hit advanced Display Settings, and change the LCD Density DPI to match the one you set in your build.prop and NOMone app.
5. Hit yes to reboot or reboot your phone if not prompted.
6. You're done! Your phone should reboot and apply your new resolution and DPI changes.
I have attached some screenshots showing off the BlissPop & Facebook UI at 1920x1080 Resolution & 370 DPI, as well as an example change in the NOMone Resolution Changer App. Lowering the Resolution and DPI is beneficial to those who want to squeeze more stuff onto their screen (it enables lots more text on the screen that isn't really big.) As well as gamers (The lower resolution doesn't strain the GPU as hard.)
If you have any issues, just delete the build.prop you edited from the /system folder in TWRP and copy over the original one you backed up and put it in the /system folder.
Known issues caused by this guide:
- Boot animation may stretch when booting.
- Recent app previews will also be larger for some unknown reason, this is a small side effect however.
Hope this helped!

I've used this application to lower resolution on my G3 to 1080p but found that the small text and other stuff was blurred because it's disproportionate to the amount of pixels, since 720p would be a more accurate number to downscale to on a 1440p screen (1/2).
Do you notice this "fuzziness"? I forget exactly which DPI I set it to when I did go down to 1080p, but the other thing I realized was that the performance gain was marginal. I did not do long-term battery testing with this, though. So the verdict is still out on whether or not there is any gain there.

I'll be testing out some other performance things and more long-term battery savings. Thanks again for the write-up. Hopefully it will help with people willing to try out different resolutions and DPI's.

Sorry, but this is the kind of thing that cannot be shown on a software level. Screenshots will not work.
The images and text is just not as crisp because since it's not 1:1 with the pixels it will naturally display fuzzy. This is unavoidable but can be lessened by using better ratios (ideally 720p, but that would just be too low) and different DPI settings. If you do not see this yourself then you may lack the eyesight. Again, it's not very noticeable and the positives may very well be more beneficial than having a perfect 1:1 ratio.

You could try going to 1080p @ 430 DPI. This makes the text similarly sized to the default 560 DPI, only on lower resolution. If you did this, the GPU wouldn't have to work as hard, and your text would still be the original size
But yeah it's worth playing around a bit. I haven't noticed any fuzziness at all at 370 DPI, and I do a lot of reading on my phone.

If you lower the resolution on any lcd screen made for a specific resolution it will make things fuzzy. You can even do this on your computer monitor.
Everyone should expect this as it is not 1:1, but I still consider it pretty useful.

Question 1080p resolution display?

Is there any option to downscale resolution of the phone to Full HD? (to preserve battery life) and lower impact on Tensor chip.
Thanks!
In a way, but it will not scale and you may have touch issues.
You could change the window manager density using adb
Code:
adb shell wm size {width}x{height}

You might save battery better by using a custom kernel like CleanSlate. You don't even need root (although you probably need your bootloader unlocked, which will factory reset your device). I'm unclear if CleanSlate also requires disabled Verity and Verification until they include the same fix that Magisk Canary 23016 has.
Let me save you the trouble: if you use that ADB command to lower the resolution on your device to 1080 it will break the fingerprint reader. What it does is offsets the button from the sensor and your are unable to activate it because the UI requires your finger be on the button but it is nowhere near the sensor. Perhaps someone else found a workaround but in my testing it broke too much and offered too little in return.

Question how to change aspect ratio of phone

hello, i wanted to change my aspect ration to 4:3 to have a stretched resolution like pc on my whole phone
there is a app called easy dpi changer. It changes resolution, the only thing you get black bars (not stretched res).
is there any way to make it stretched instead of black bars?
here are some screenshot how it looks like after resolution is changed.
thanks
If you stretch 4:3 to fill the 20:9 screen you'll end up cutting off part of the display.. so I think it's not an option

I know it, but thanks for the tip anyway.
It needs root and I'm actually unrooted.
Other apps just works with adb, like P ixels:Resolution+DPI changer, in playstore.
(#com.tribalfs.pixels) if searched outside.
I think it also has more option than the one you mentioned.
