Hi everybody,
I have the official MHL -> HDMI (Tv out) for my SGS2.
I sometimes used it to watch movie on my television, it worked very well (with the 2.3.5 Gingerbread version).
(It doesn't work with ICS AOKP)
Now I'm on JB AOKP ROM (TV out works only for video, you can't see ont the TV the launcher, browse the phone,... (it's ok on the phone) but video with MX Player works on the TV).
When I try to watch a portrait video I have made, the video is rotated like it was a landscape video. (I have to turn the head )
Today, I have try the new JB Samsung ROM and I try to watch some video (recorded in landscape and in portrait mode) that I made with JB AOKP Rom and JB Samsung Rom.
I have an other problem.. A video in portrait mode is stretched like it is a landscape video. (People on the video look fat )
It's strange because with the JB Samsung Rom the TV out is fully working : you can write messages, browse the launcher and some apps in portrait mode and on the TV, the portrait mode is respected. But it's going wrong with a video in portait mode (recorded with AOKP or Samsung ROM)
Did someone notice the same problem ?
I think that I can remember myself that on gingerbread, the video in portrait mode were correctly played in portrait mode with the TV out... =/
Is it a problem with the MHL TV out or a problem in the video encoding ?

What does this app do?
It allows to change the resolution and the pixels density of the screen to pre-defined settings according to standard screen aspect ratios
Why is this useful?
- Watching Video on an external monitor/tv using the hdmi output will usually mirror the screen content without correcting for aspect ratio, by setting the correct resolution and pixel density of the screen to match the monitor/tv allows to fill the entire external screen and avoid the side black bars.
- Playing games on an external monitor/tv: normally, the device will render the games to the full resolution available on the device's screen. On the case of the Nexus 10, games will be rendered to its huge resolution of 2560x1600 and then it will be scaled down to the monitor/tv screen resolution wasting GPU prepossessing power and resulting on more heat and power consumption during gaming. By reducing the screen resolution to match the external monitor/tv less processing power is needed to render the game at the lower monitor/tv's resolution, many games will even use the extra processing power available for more effects or more frames per second (depending on the game, no established by this app).
- Simulate other screen resolutions and pixel density for android developers to test their applications on the physical device and observe how their application will look on other devices.
Available options:
-Manual Settings: Allows to manually select the desired resolution and pixel density according to pre-defined standard aspect ratios.
-Auto Detection: Will run in the background and will detect HDMI connections and disconnections. On a HDMI connection detected, a notification will be presented to apply the detected screen resolution and pixel density appropriate for your screen. On a HDMI disconnection, the notification will allow to return to the device's default settings.
Reboot Mode: New Soft Reboot will only reboot the graphical interface not the entire system (Fast). Normal Full Reboot (safest, use if you find interface issues with the Soft Reboot).
Screen Size: Define your screen size (affects dpi calculation). This setting comes pre-defined for the nexus 10, but you should change it to match your screen size on other devices.
HDMI Resolution Preset: Define your preferred output resolution instead of using the Auto-Detection option .
New Default Settings: The default settings will now reset the dpi value to the factory configuration. It appears that the nexus 10 comes from factory with a dpi setup to 320 instead of 300. The new reset feature should also work for other devices.
Auto DPI Selection: No more guessing work, it will select the appropriate dpi value for the selected resolution and the screen size defined on the settings.
Screen OFF feature: Allows you turn your device's screen off while keeping the output to the hdmi to reduce the power usage. To turn the screen back ON just press the power button twice or simply disconnect the hdmi.
Touchless Profile: It applies the profile automatically upon hdmi connection without user interaction.
- The profile can either auto detect the TV resolution or apply the preset resolution
- If selected, it will turn the screen off automatically when the hdmi is in use.
- On hdmi disconnection, the screen settings will automatically return to default.
What is New
New Recovery Feature: Recovers the default screen setting after an user specified number of power/charger connections. Will restore the device if the user applied a configuration not supported by the device.
To trigger the recovery feature, plug and unplug the power/charger to the device allowing ~1s between plug/unplug as many times as defined on the settings menu, default is 3 times.
v1.27:
- New Recovery Feature to restore default setting upon cycling the power connection 3 times at ~1s between connections.
- Fixed interface issues on Nexus 7 2013.
- Support for small screens up to 3.5"
- New first time setup to ensure the user select the appropriate screen size of their devices.
- Added the screen size to the current settings display.
v1.26: Improved the Preset Resolution Input dialog to avoid incorrect inputs.
v1.25: - Improved support for devices that are naturally oriented in portrait mode (i.e. nexus 7, cellphones, etc).
- Added more resolutions, specially to support smaller devices and cellphones.
- Added "Touchless Profile" option.
v1.24: - fixed a crash issue happening on devices that did not have BusyBox installed. if you don't have busybox installed, the app will now prompt you to install it.
- fixed the Auto-Brightness feature that was awakening the screen for some devices on ambient light changes.
- Added Screen Turn OFF request for support on devices where screen turn off is not yet supported.
v1.23:
-Improved screen OFF detection mode to support more devices. Allows you turn your device's screen off while keeping the output to the hdmi to reduce the power usage
v1.22:
-Screen OFF feature.
v1.21:
-Adjusted App's interface for portrait and landscape mode, and smaller screens.
-Back compatibility with JB 4.2
-Added preset button on main application
v1.2:
- Auto DPI Selection.
- Reboot Mode Selection.
- Screen Size Selection.
- HDMI resolution Preset option.
v1.01: Code cleaning
v1.0: Initial Release
Why a reboot is needed to apply the new screen settings?
- For now the safest way to restore the entire Interface with the new resolution and pixel density is to reboot the system. The new Soft Reboot should reduce considerably the time required to reset the interface.
MOD EDIT: Link to Google Play Removed due to XDA advertising paid app/theme policy. OP can check for PM from me.
This sounds like an interesting app!
Gonna try it out, but I have a few questions, does the resolution change happen only when connected to a HDMI output? Are there any benefits to having a lower res for say regular daily use of the tablet, say like not hogging the gpu or lowering the gpu temperature?
Also, according to Xda rules you shouldn't advertise paid apps here, you either have to make a free trial or this post will get removed, but I would love to keep the thread alive...

s1m4an,
I did not know about the paid app rules for posting at this forum; however, I am planning to release a trial or beta version specially to bring support to other devices.
You can change the resolution at any moment (without HDMI connected) by opening the app and selecting the desired resolution and pixel density and then apply the changes.
The HDMI detection just allows you to change the settings to match the detected external screen automatically without having to worry about what resolution and density you should select.
Lowering the resolution will definitely reduce the GPU utilization and GPU power consumption (heat generated) especially at graphic intensive apps like games, even at 1080p the GPU needs to render half the amount of pixels than the default resolution. I have tested this with games and I generally gain frames per second or I am able to increase the detail level of the game effects. In normal usage, GPU utilization will also be reduced but I will imagine that non graphic intensive applications will not give you such drastic difference, probably watching movies will.
Another benefit is that it allows you to test how applications will look on other devices, if you are a developer.
Thanks for the comment,
Yes i would be great if there was a trial version or something like that.. It sounds interesting..
Hi forbitel, I bought your app and I like it so far. Works fine with stock 4.3 and it's a very easy way to have a true full screen 16:9 trough HDMI. Shame to Google for giving a stupid 16:10 aspect ratio to our HDTVs.
I have better results with 16:9 2560x1400 with my tv
Setting 1920x1080 creates a weird interface in the tablet. Looks like a old phone launcher...
What I would like to see in a future update is to set a favourite resolution when HDMI is detected so we don't have to go to the app every time we want to change it.
Good work!

King Conan, the preset option added to the newest update should now do what you want.

Yes I saw the update. Thank you!
I'll try in the next hours.
But now I have a problem. I use the keyboard app "Swiftkey Tablet" and even after several reboots, going to default resolution and reinstalling the app, it's size is like 3 times the normal. It's like the app thinks I'm still in 1920x1080 and not in the default 2560x1600. And I can't use it...
The stock keyboard works fine.
I'll post a screenshot later!
Edit:
Maybe reinstalling the app was not the solution (it may keep settings in SDmemory). I'll try to erase app data and reinstall.
Edit 2: Solved.
But I really want to thank you for this app. Now I can use Nexus 10 as decent multimedia player with my TV.
New problem: sometimes I have to apply and reboot up to 3 times to get the desired resolution. I have to test more...

What specific resolution and density are you trying to set? is it through the main application window or through the hdmi notification?
I see you updated the app again.
First try and success, resolution changed fine.
I'll try more.
With this latest update everything works great. 1 reboot needed to change resolution and its very easy to have a preset one.
Sounds like a really useful app. Unfortunately I don't really want to pay for until I know it works for me. I will probably pay once the app matures after a few updates.

Well, the updates are coming non stop. It works perfectly fine now and the latest update brought a great new feature: Screen off with hdmi out active.
With this app we can have finally a serious media player with the nexus 10.
Congrats to the developer.
@forbitel
Can you tell me what's the shell command (that you have implemented in the app) to "soft"reboot the GUI?

How did you solve the keyboard problem? I was seeing the same thing but could not find a solutuion.
And what screen resolution settings are you using now that will work perfectly with your TV?

mrruin,
I have tested few popular keyboards from the market and found the following:
- Google Keyboard: Adjust the best out all I have tested, it consistently adjust with changes of screen resolution.
- SlideIT: Somewhat adjusting to the screen resolution changes, works better than Swype and SwiftKey.
- Swype: do not dynamically adjust to screen changes, some resolutions works but wont adjust to the screen on 1080p.
- SwiftKey: do not dynamically adjust to screen changes, some resolutions works but wont adjust to the screen on 1080p.
I would recommend you use Google Keyboard when changing the resolution of the device, until these keyboards are fixed for resolution changes.
Where can I get that wallpaper?? That looks really cool.
So when are you going to release the trial betsa version like you said you would ? It has been almost 2 months

Nexus 5 slimport HDMI
Has anyone had any luck changing the HDMI resolution?
On a Nexus 5 or any other device?
I have tried all combination of settings i can think of but it either boot loops or resolution stays on 1080p.
Im guessing when it boot loops with the cable plugged in its trying to output 720p but doesn't like it much.
I'd like to provide some sort of log if would be useful.

normskilight,
I haven't tested the application on 4.4 KitKat yet, I just got my KitKat OTA few minutes ago.
I will test it soon and will get back to you.
Please keep tuned.
Regards,
I have a Sony Xperia Tablet Z (1920x1200). With original 4.1.2 it would correctly scale the picture to 1920x1080 when connected to my TV with MHL/HDMI-adaptor. Since 4.2 and now with 4.3 update it will not change the resolution and displays a squeezed 1920x1200 picture on my TV. So the aspect ratio is corrupt, making wide faces etc. when watching photos or movies.
Sony says that it is Google's fault.
The Xperia Tablet Z has a hidden service menu where I can change the HDMI resolution but it is set as 1920x1080 as standard, and changing this to 720p does not correct the aspect ratio issue.
I have bought the app Screen Settings from Forbitel, and I have also tried other resolution changer apps, since I am rooted and have Busy box installed.
I am able to change resolution to 1920x1080, which displays correctly at my Tablet Z (it leaves 120 pixels unused =black bars at top and bottom) BUT when connected to my TV it will still only display a squeezed 1920x1200 picture on TV screen!
Why has Google removed the scaling from 4.2 when it was working perfect in 4.1.2?
Any information regarding this or ideas how to fix it would be much appriciated! Thanks!
