[DEV/APP] Resolution changer for HDMI Landscape Mirroring on Blur System

djeman · Feb 22, 2012

This application will allow you to change the resolution of the mirroring mode.

To use it, you'll have to re-sign it with the same signature as the system, if you successfuly installed the mirroring mode you'll find a way since the problem is the same.
You'll also need to change the package MirrorService.apk because I changed an option in it to allow the use of the function that will change the resolution for all kind of android builds (eng, user, userdebug).

It's a really simple software, it just requires to activate the mirroring mod to be able to change the resolution, you'll keep it to until the next change or reboot.

Language : English/French

Download v1.0.2 : https://rapidshare.com/files/225894882/MirrorResolution.apk

MirrorService.apk from Photon modded : https://rapidshare.com/files/426697782/MirrorService.apk

Source : https://rapidshare.com/files/2349891096/MirrorResolution_source.zip

To achieve this I used the hdmi user library from the motorola addon pack for atrix.
Pack available here : http://developer.motorola.com/docstools/tools/
Docs : http://developer.motorola.com/docstools/library/motorola-hdmi-dual-screen-api/

I reverse-engineered the mirroring service to create an user library to use with Eclipse.

Awesome job, mate!

Nottach · Feb 17, 2012 at 2:17 AM

Very cool.
Works good on NottachTrix. OK to add to the next release?

One question, are the resolutions labeled correctly in the chooser? When I choose 1920 x 1080 60hz it defaults to 800 x 600. But when I choose 1920 x 1080 50hz it applies 1920 x 1080 60z. I know my monitor doesn't do 1920 x 1080 50hz so something seems weird.

I installed the app and replaced the mirrorservice.apk but your mirrorservice file broke my mirror :S

I tested only with the app itself and it changed the resolution, but it just displayed an static image of the app and never changed.

Also, when selecting 1080p, stayed in 720p, but selected 1280x1024 and changed to 1080p.

How can I fix the mirrorservice.apk? What did you change ? maybe I can edit my apk

The signature of MirrorService.apk needs to match your systems sig or else it won't work properly.
I first installed his resolution app and tried it out with my regular mirrorservice and it didn't work.
Since my rom is already totally resigned I just resigned his mirrorservice.apk and pushed it and then it worked properly. (except for the res labels)
depending on what rom youre using you can try resigning his mirrorservice and pushing it to see if that helps. it should work if youre using one of my roms, not sure about cm7 roms though.

Actually, pushed back the original mirrorservice, and it kind of works, but like you said, the resolutions are not correclty labeled... 1024x768 is 1080p on mine, but it works after a restart

how to resign?

I decided to install signapktic to resign the app, but had a couple of questions. You say to sign using signature of my system. That is not the testkey, correct? So how would I obtain the signature of my system? Also, do I sign both apps or just the mirrorresolution.apk?

I also feel like I'm completely missing the point of signatures on apks, but I'll figure it out in due time.

Notorious544d · Feb 17, 2012 at 12:20 PM

Just to confirm, does this work on CM7 ROM's, or is it only for Blur?

djeman · Feb 17, 2012 at 2:12 PM

For the list of resolutions, I get it of your extern monitor and based on the motorola doc.

Code:

static final int HDMI_STANDARD_INVALID       = -1;
static final int HDMI_STANDARD_AUTO          = 0;
static final int HDMI_STANDARD_2_3_60HZ      = 1;  // 720x480P @ 60Hz
static final int HDMI_STANDARD_4_60HZ        = 2;  // 1280x720P @ 60Hz
static final int HDMI_STANDARD_17_18_50HZ    = 3;  // 720x576P @ 50Hz
static final int HDMI_STANDARD_19_50HZ       = 4;  // 1280x720P @ 50Hz
static final int HDMI_STANDARD_1_60HZ        = 5;  // 640x480P @ 60Hz
static final int HDMI_STANDARD_16_60HZ       = 6;  // 1920x1080P @ 60Hz
static final int HDMI_STANDARD_31_50HZ       = 7;  // 1920x1080P @ 50Hz
static final int HDMI_STANDARD_PC_SVGA_60HZ  = 8;  // 800x600 @ 60Hz
static final int HDMI_STANDARD_PC_XGA_60HZ   = 9;  // 1024x768 @ 60Hz
static final int HDMI_STANDARD_PC_SXGA_60HZ  = 10; // 1280x1024 @ 60Hz
static final int HDMI_STANDARD_PC_WXGA_60HZ  = 11; // 1440x900 @ 60Hz
static final int HDMI_STANDARD_PC_WSXGA_60HZ = 12; // 1680x1050 @ 60Hz
static final int HDMI_STANDARD_PC_LD_60HZ    = 13; // 1366x768 @ 60Hz

On my LG tv all res are ok.

And no problem to use it on all roms you want, i shared it for that

I don't see an apk with that name in system/app on my CM7, so I assume it's for Blur.

how do i fing the correct signature to sign the apk with? im about to do so now but im slightly confused as to how to locate said signature

Nipit · Nov 2, 2010 216 17 0

Sadly, it doesn't work on cm9 turl v8. It says searching for tv, while my tv displays atrix screen. Why it doesn't find it? Anyone else having this problem?

djeman · Feb 22, 2012 at 7:29 PM

It's build to work with motorola dual screen api sry ...

What do you mean by that? People confirmed that this worked fine on their TVs. Anyone else having troubles on CM9?

Thanks for making the app. I'm just curious on the purpose of the app. What's the advantage of manually modifing the HDMI resolution? Currently, when I plug the Atrix to my HDTV, it always defaults to the maximum screen resolution of the connected display. In my case, it's always 1920x1080 60Hz. To my understanding, your app allows me to modify to lower screen resolution. However, is there any advantage on doing this?

Hi Djeman,

That can be awsome if you can work on it for CM7 based ROM, I'm on Neutrino and this is the last thing I'd like to get !

Thank you in advance.

i don't see any post with cyoagen mod roms claimed to be working with this. wish it was....

Rotkaeqpchen · May 15, 2012 at 9:16 PM

Unfortunately it doesn't work on my Droid 3 5.7.894, am I doing something wrong? After replacing MirrorService.apk there is no HDMI mirroring anymore and the app says not mirroring... Help is highly appreciated.

THANKS
