I have just installed gentoo on an intel NUC i7 (NUC5i7RYH)

It's a great little machine but I have one problem

The NUC has one mini displayport video output and one
mini hdmi output

the hdmi output works (actually not quite - it leaves black
bars on my 1440x900 old TV instead of filling the screen)

But if I use a displayport to vga adapter I get a black screen
and "no signal" immediately after the grub prompt. I can see
the grub startup page but after that nothing

The displayport > vga adapter works fine in mint linux however

The graphics are intel i915 ("iris 6100") and I'm running the 4.1.1
kernel ...

If anyone has a clue what's wrong with my setup, I need the help.
