It happens several times a day that the screen gets black but HDMI signal is available (the screen doesn't go to standby because it recognozes the HDMI signal).
It remains black even if I unplug and plug the HDMI cable again.
Also, the ODROID-N2 remains reachable on the network and I can ADB into it.
I tried to connect it to another monitor when it happened but it didn't help.
I also tried the following in /odm/boot.ini
Code: Select all
setenv suspend_hdmiphy "0"
The only thing that helps is a reboot.
I believe that it happens more often if no screen is connected for a while (maybe 30-60 minutes) and than when it gets connected the screen is black.
What is it?
