Good Day,
I had the same issue with Kernel 4.4.6 but using a current kernel does not solve it.
The second screen is connected but not recognized as such.
During boottime I see the console on both screens with 4.0.5 but on 4.4.26 only one

I've tried to run xorg with an empty configuration but it does not solve the problem.
If I'm trying to run X -configure i'll get the following result:

I think kernel 4.8.4 is recent. The others are antique with backported features / security bugfixes
May I ask why you have to use kernel 4.4.x ?
Personal opinion => these are antique kernels 4.0.5 but on 4.4.26 only one . When you do not have a use for those please update.
Are there any bad configured xorg.conf / other config files lying around which may cause issues? |

| I'm using this kernel version because it's the latest my portage tree provides (without unmasking). Furthermore I do not assume that there is a bad xorg.conf because i've tried it with a default one |

You are aware of that newer kernel sometimes fix issues regarding hardware compatibility / bugs / security ...
There is nothing wrong to unmask gpu driver / kernel.
Choice is up to you
First thing what you get asked on bugs.kernel.org is to try with latest kernel. so .. |
