in Android - if it had been in kodi i had mentioned it in android you can set the screen in settings to auto 1080 60hz 1080 50hz 1080 24hz . . . . . if you set it to auto - it will not be fixed there - only the other settings will be fixed oki?
Sorry, now I understand. I'm not connected through HDMI, so I don't see this settings... Good to know. And this question needs an answer.
an "auto" function is something that will check your connected devices to set the best settings ; it checks at startup of course, but also in real time, so it cannot be "saved" ... edit : sorry, I did not understand what you really ment, my answer here is out of subject :/ and you are right, zidoo doesn't stay in auto mode after reboot
