MHL HDMI Screen Resolution

Hi,
I want to change the screen resolution of the MHL output because it's not correctly detected maybe because my old monitor or the hdmi to dvi adapter. I wonder there is no native menu to configure the resolution and audio output device or an alternative app... My device is rooted.
So the screen settings are here:
/sys/devices/virtual/graphics/fb1
There is a thread for the evo http://forum.xda-developers.com/showthread.php?t=2090396 but on my One there is no hdmid service and no video_mode.
Available is a file named modes which probably contains all available modes and a file named mode which maybe should contain the current output mode.
modes contains in my case U:640x480p-0 and U:640x480p-94
mode contains nothing if I echo an value into its also empty after that.
The monitor supports a maximum of 1280x720.
Is there someone with deeper android development knowledge who can help in that case?
Thanks,
Patrick
Edit: Maybe I get 640x480px because of HDCP protection problems - is there any solution to get the HDCP back to work on a rooted phone or disable it? In the developer menu there is no setting for that

Custom ROMs that support MHL or HDMI respectively

Hi,
before installing a custom Rom to my Sony Xperia Z1 compact I did a lot of googleing to figure out if there's a custom ROM that supports video output via MHL/HDMI. I only found threads saying that MHL is not supported by any ROM other than the stock firmware.
But today I made a different experience and wanted to share this. I tested some ROMs from CyanogenMod and Free Xperia. MHL output was actually working with:
- cm-11-20141112-SNAPSHOT-M12-amami.zip
- FXP-cm-11-20150301-UNOFFICIAL-amami.zip
So both ROMs based on kit kat worked. But I had to plug in the the connector several times and rebooted once before I actually saw an output. It's actually mirroring the screen to an external screen, also rotating as the phone is rotated. But picture was always orientated upright.
On a Dell FHD computer screen scaling was squeezed vertically, on a HD ready TV screen scaling was fine.
I also tested CM12 and CM12.1 but didn't get an output with the ROMs tested.
Would be great if others could also share their experience with MHL/HDMI with their custom ROMs.
Thanks

how to change output resolution on Pine64 with Remix OS 2.0 to work with NexDock

I received a Nexdock which is basically a display and a bluetooth keybord. The idea is that with Nexdock you can turn your Pine64 computer into a laptop.
More info on NexDock on indiegogo.com
I'm running RemixOS 2.0 on my Pine64 2GB but I can't change the output resolution of the Pine64 to 1366x768.
1366x718 is the native resolution of the Nexdock.
Nexdock works together with Pine64, but all text is hard to read because of the wrong display setting.
When ordering a Nexdock Nexdock claimed compatibility with Pine64...
Any solution or Remix OS update to fix this issue?

I'm on the same boat as you.
Running debian the display is using the right resolution but obviously there's no GPU acceleration and no bluetooth working.
Bluetooth will get a fix in the future probably but I have little hope for GPU on debian. That means no usable Kodi-
At this stage of development Android (and RemixOS) seems to be the better solution for the Pine64.
On PC you can change the vesa mode at boot but I don't know how to do it on Pine.

Ok. I don't have an available SD to burn again RemixOS but could you try this?
in settings> experimental features >enable debug terminal console
press Alt+F1 this will opens the console
type wm size 1366x768 hit enter
press Alt+F7 to exit

Debug window
Unfortunately, that option seems to have been removed for the Pine build. I tried alt+f1 to see if maybe it was enabled by default, but no luck.

Question [FuntouchOS] How to enable Desktop Mode?

I am not able to enable the Android12 Desktop UI on my Vivo X80 Pro.
The Phone was pluged in to a USB C Hub with HDMI Port. but it just mirrors me the Phone Display.
I've already enabled this Feature in the Developer Options (Force Desktop Mode).
But it does not work.
I am more and more annoyed about the software.

I was wondering the same thing
but at least, having video output is a good start

Can anyone confirm if desktop mode is working on funtouch OS?

Can anyone confirm if desktop mode is working on funtouch OS 13 for vivo x90 pro?

it is not working on the X80 pro
you could check the x90 dedicated threads and see, but I expect it to not work as well

Question Desktop mode working?

Hi,
I've been trying to get the desktop mode to work on android 12 OriginOS but all I'm getting is a blank screen with navigation buttons (either while if I pick light theme, or black if I pick dark theme)
When the phone is locked, then the clock appears on the external monitor
I tried 3 different adapters / cables but getting same results
Only app so far where it works 100% is VLC: The video will properly play on the external monitor, in full screen (no tearing visible or any artifacts)
Has this been fixed on android 13?
Did someone manage to get the desktop mode to work?

cam someone with android 13 try this in the developer options -> 'Force desktop mode'?
Does it display anything?
Thanks

I've tested it on OnePlus 9 Pro running Android 13 on a Huion Kamva 13 tablet and I could see the desktop screen on it. However pen was not working at all.
Hoping that Android 13 improves on it, anyone being successful or seen improvements over Android 12 version?
How did you get apps on the external monitor? I was unable to move an app from phone's screen to external screen, any options?

havent heard back from anyone running android 13...

finally updated to android 13 (x80 pro, snapdragon W10 variant) and can report that desktop mode is NOT working
only mirroring of whats on screen works
very disappointing from Vivo
