[ale] OT: HDMI cable - Android question

[Boris Borisov]

I have two Android tablets with broken displays. I'm thinking of
reusing these as NAS or something similar.

Q. For whoever have tried this. When you plug your mini HDMI cable in
your Android device and boot the Android is the screen appears an TV
or you have to switch it from the HDMI output app? Etc. is Android
recognize HDMI cable at boot and switches to HDMI output or not?
