[Q] Optimus 3D HDMI output resolution?

Anyone here used HDMI to output to a 1080p screen via HDMI? What is the resolution of the image seen on the TV? Just 480p or actually genuine 1080p.
1) eg a photo seen on the phone screen will only ever be 480p, so mirroring thet same photo displayed on the TV will see much more detail? or just the same 480p resolution only on a bigger TV?
2) Even if you did have USB charging during use, would the drain-rate of playing video via HDMI out strip the charge-rate?
Thanks in advance for your feedback
Here's my side of the story

I start by saying that I use a 1.4 HDMI cable made for Sony Ericsson phones that I found at 10 euros. My settings for HDMi output are 1080p at 50Hz - I must say that leaving it in automatic is bad cause it does like 480p as output resolution.
For photos the output fine, the 1080p and looks great, even the 3D photos. But when I'm using the camera while the phone is connected to TV the output is not 1080p but, IMO, a poor 480p. Same story with videos - while playing them give you the resolution on which they were recorded, on "live show" you got only the 480
The home screen is seen on TV at its native resolution not HDMI. The games are on the same boat, at screen resolution and not HD. Not even with the games that declares themselves HD is not working.
On the second issue: yes - the HDMI playback while charging DOES strip off the charge rate, finding yourself that after a 20 minutes of video playback while charging you have no juice left in your battery.
In my opinion the HDMI out is useful only in few situations: dual boot on the phone, letting you to use it as a computer (but this implies the USB Host active on our P920 - which still is missing), playback of files on the phone which would be impossible to play on TV - here you might get variations based on the TV set that you might own and the final use I foundshould be to use it as a game console but this also implies to have a bluetooth activated controller because playing with the phone while connected to the TV is just... a big NOOOO - only in some games that implies only the use of accelerator sensor, like racing games.
I hope that this is useful to you. I voted the second option - I use it but I'm not addicted.
Excellent response! Can you tell me how
To set 1080 output output on
the o3d because I have HDMI link but cant find the android setting page. My current setup must be in auto because photo gallery looks like worse than 480p on my TV right now.

for setting HDMI go to settings => HDMI => Resolution and select from the options available (1080P at 60Hz or 1080P at 50Hz)

Have you tried to set higher resolution within Ubuntu? Like setting screen resolution. I might think it would work because will force the phone to give the application's resolution (still running Ubuntu is like running an application, because Ubuntu is not set in dual boot with Android on the phone but is working through a Virtual Machine, if I'm not wrong)
Can you tell me how you've managed to run Ubuntu on O3D? Thanks
i got another problem that is way worse. i got sound failing during videos are playing. in the movie player or in youtube, all the same, it keeps failing. the sound stops and then starts again but the image has no problem.
Nope... non. On my stock phone. Simply
No sign of HDMI settings

[Q] HDMI Connection only 720P. Any idea how to change it to 1080P?

Hi,
I am owner of a Sony Xperia Tablet S with a docking station(using to connect to a TV through HDMI cabel). When I connect the tablet to my TV(Samsung 1080P) It is only recognized as 720P device. That's probably OK, but when I play 1080P movie It should change to 1080P video resolution but it doesn't happen. I tried to search for a HDMI output setting in the tablet but there is no such thing, I also tried several video players, even to play exact resolution size video - 1920x1080 no change... still only 720P. And to be honest 720P doesn't look very brilliant from this tablet. I hoped to use the tablet as some kind of "all round video player".
Is there any way that I can convince the tablet to play videos in 1080P/Full HD? Any idea how to resize HDMI output resolution?
I know that it is mirroring my device, but even though it should automatically resize when playing full HD movies. (Saw it on couple of videos, where it does really work. The TV shows 1080P videos and the devices screen stays black, I guess because of their lower resolution, but that's OK.)

I guess, your tablet only supports 720p output via HDMI.. It may be your TV only allowing 720p for HDMI output. Check your TV settings...
Hope this helps!

My TV is 1080P I am 100% sure . The TV finds by itself that it is 720P and I cannot change it anywhere in the TV menu(or in tablet). It seems that the tablet sends only 720P - which is OK, but when playing movies it should change to 1080P. The tablet itself should also support 1080P. If I could only get to service menu - there are the settings and I could change the output resolution.
Even though it doesn't seem all newer sony smartphones/tablets should support 1080P. In the service menu it is just matter of few clicks to change the resolution. I don't have permission to send links here, so type on youtube: Sony Xperia S - HDMI - Playstation 3 Controller

Well, nearly all TV's support 1080p (4k is next ) So I guess its the Sony software limiting it. Your specs can easily output 1080p. Although the software may be limiting it, try converting the video files to 1080p resolution and give that a shot. Also I have watched a demo of the xperia s tablet in HDMI mode and some parts on the TV screen are cut, so I'm guessing it ONLY supports 720p (unfourtanatly)

I already tried to play 1080P movie with exact resolution no luck... The TV/Tablet hardware are capable of it, even android as software, but sony gave no option to change the resolution anually, which most manufactures don't, but they change to 1080P when playing 1080P stuff.
Only thing that is cut is the bottom navigation bar(I'm not sure how you call it.), but that's ok because the tablet is 16:10 and the TV is 16:9 so It just cuts off the black bar with navigation buttons from bottom. Otherwise it shows 100% from the screen.
As far as I know service menu would help to change it(easiest way), or some kind of app that can change HDMI output resolution? Or app that can change the resolution of the tablet itself, than I guess would the TV recognize the device as 1080P. Any idea?

Well, if you want to mimic the 1080p output, then a program that uses root may be required. However, Im not sure if there is such app..
Your tablet doesnt probably have 1080p stream output capacity. Maybe you could plug it to a device with an upscaler

I don't want just upscale the resolution. It won't make image any beter. As I know Tegra 3 does support 1080P, android as software too... so I can't see why it doesn't want to work? My girlfriend has also a Tegra 3 tablet(ASUS) and far as I know when she is playing 1080P it is a real 1080P on the TV and the screen(on the tablet is 720P) just stays black, I mean control buttons and everything is there, just the area where should the movie play on the tablet is black.
It seems I will have to root the tablet omg... Does anybody have an idea if there actually is an app like that? That can send it as 1080P output resolution? I tried to find service menu...no luck... if I could get there, like on the phone it would be just matter of few clicks and 30seconds of work...

Current status of 1080p playback on original MK808?

Hi all,
just got me a benq w1070 projector and tried some 1080p 3D files on xbmc 13 and performance was abysmal. I have the Finless 1.7 installed since last year and although 1080p files play more or less ok, 3D content is simply unwatchable. Performance is kinda better on MX Player but there are still frame skips and stutters. What I'd like to know is what firmware (+ kernel?) can I flash on my original MK808 to boost its HD playback quality? I have installed a GPU fan on it since day one so overclocking shouldn't be a problem. Thing is, I tried reading about MK808 1080p options and got lost as some developers don't support it anymore, links are dead etc. Thanks.

Can not Crop video - ONLY Stretch - Amlogic S812 Android TVbox and SONY AndroidTV

Dear All,
I just bought an Amlogic S812 the Android TV box to replace the old one (Allwiner A31s Android TVbox)
Currently when watching movies with the software MXplayer , it can not Crop the Screen Size to remove black place on top and bottom of screen, it only can use Stretch option to stretch vertically, does not stretch horizontally, so making everything in movies stretch out :crying:
I do not experience this problem on older devices using Allwiner A31s chip.
Pls help me fix this issue
P/S: I face this issue on SONY Bravia 55X9000C Android TV too.
Thank you all.
Anybody??
Same issue with the newest s905x3 chipset, Android 9.0... I don't have all the options in my settings, I can't even place apps on homescreen using Nova Launcher, I can't see the bottom drawer to open all running apps. Do manufacturers modify the Android version they put on these boxes? Is there a way to fix these issues, especially the video player cropping? In my box no player can crop, only stretches vertically, leaving me with an incorrect aspect ratio.
Hi everyone.
This may be a solution.
I get to realise that this thread has a long history and there is no proper answer.
I too had the same problem while using MX player in Android tv. But some video are able to crop view. After many thoughts I get to realise that there are two kind of popular encoding in mkv format.
Videos encoded in H.264 have no problem. But if it is H.265 commonly known as HEVC it will no crop or zoom in.
I currently use H.264 video for maximum use of my tv screen.
Please Google these encoding method for better understanding. There are some interesting comparison between two.
Happy watching
