Issue: When i power off the Odroid N2 and turn it on next day, in the first about 1-2 minutes i get very often a black screen on my monitor. The signal is gone. The monitor goes into standby mode. I never had this issue with any other hardware. I have to disconnect the HDMI cable from the odroid and connect it again. The screen then get back again and works from there on. I cant find any errors or even event reports in dmesg.
