None of this worked. My computer stopped seeing the other display (TV) just like that, even though it’d worked the day before. TV and HDMI-cable are good. The IT-service checked the HDMI-port to find it without any damage. I’m totally clueless about it. The only thing left is to restore the system to the initial settings, but it doesn’t ensure me that the problem won’t arise again.
