If started with monitor switched off (via ssh -X for example) it will always report Display does not support DDC even after turning it on. The only way is to restart application.

Unfortunately, ddcutil only performs monitor detection at startup.  This is not a problem for the command line version, which just detects monitors, performs an operation, and terminates.  It is a known issue for ddcui.  In the best of worlds, the library would detect a monitor change, scan the new monitor, and notify ddcui of the change.  Simpler to implement, but still requiring API enhancement, would be a Rescan Displays entry of the Actions menu.  It's on the TODO list - the GUI hooks are already there.
