As a matter of fact I discovered that kernel 3.13.0-61 was not the reason to make it work again, at least not the kernel itself. After rebooting the running kernel was still 3.13.0-62. But this time the HDMI worked. Maybe the process of installing had a certain side effect. I don't know. Now I am running kernel 3.13.0-63 without any problems.
