My board serves as a file-server.  Normally there is no display connected. I have access via putty over the network. I only want to connect a screen via hdmi directly if there are problems with the network. But then I have a black screen. I only get a display if the screen is connected from the boot. Can I change this so that I get a display when I connect the screen at any point on the fly?

I think LCD script bugs the HDMI hotplug. Try the following:

1. Execute the "olinuxino-display" script in the command line interface and set to "DISABLE" option at the bottom, reboot, and test a few times if the HDMI now works as you want.

If the issue remains:

2. Run again "olinuxino-display" script  in the command line interface and set to "Auto detection (without TS)" option, reboot, and test a few times if the HDMI now works as you want.

Let us know how it goes.

Following the first hint with the script and "DISALBE" option has already brought success. The display now works, no matter when I connect the monitor.
Many thanks!!
