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:
There is a thread for the evo http://forum.xda-developers.com/show....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?
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
