Hi,

ok thanks fritsch for your help. In the meantime I found an article here: http://www.arunviswanathan.com/node/53

I installed an ubuntu desktop (also 16.04 with same kernel) and tried these steps and it worked. Unfortunately it looses this settings after reboot.
So the driver in gerneral is capable to do that only the monitor is not recognized properly.

So maybe it's easier than I thought...I just have to add a custom mode permanently. Do you have an idea how to do that?

Thanks

Alex
