--- Comment #32 from Karin Willers <karin at visti.de> ---
We verified the open question from comment 24 above:

[4] HSW UEFI BIOS + GOP + WIN8.1   = OK

OS was Windows 8.1 Enterprise with graphics driver win64_153618.exe from
the Intel web page.

The monitor was properly detected when initially unplugged at boot and
attached later with:

o  native DP connection
o  active DP-to-DVI adapter
o  two types of passive DP-to-DVI adapters

Win 8.1 in CSM (i.e. non-UEFI mode) and VBIOS is also working as expected.
