I have a strange issue with my Odroid.
I generally use my Odroid headless so I don’t connect my monitor to it. I connect my Raspberry Pi to the monitor most of the time.
Sometimes I want to switch the devices i.e. connect the monitor to Odroid while the Odroid is still running.
But I don’t see anything on the display when I connect i.e. there is no output.
The only way I can see the display again is if I reboot the system and then everything works as normal.
i do not have the same issue here… just try it usually use a KVM switcher here to switch display but also when i do plug HDMI directly it turns on even without any needed trigger like keyboard stroke or mouse movement
Since @joekamprad doesn’t have a problem, could it be that the HDMI Monitor itself isn’t handling a hot plug correctly? Especially if the monitor is a HDMI TV then hot plug normally isn’t something that happens on a TV.
I plugged in the same HDMI cable and I am able to see the screen normally now.
Uptime is 15 hours. My observation is that it stops working after the system is up for a while.
I’ll try again tomorrow and update you guys.
Thanks for all your suggestions.
