Hi
In the last two years i have changed 12 pc's to nuc's in our accounting.
8x NUC-D53427RKE
4x NUC6i5SYK
Everything works and all members are using the dual screen mode (MiniDP/HDMI)
and now 1x NUC7i5BNK
The new nuc will have a Thunderbolt/HDMI Kombination. So there is my problem.
I understand only one graphic pipeline is connected to the Thunderbolt port.
My monitors are LG 22BK55WY-B (posible connection options are DisplayPort 1.2, DVI-D mit HDCP, 15 pol. D-SUB)
My operating system is Windows 10 with all updates.
Normally i know when the nuc is turned on i see the intel logo on both monitors while booting. (so i know both monitors are recognized)
But this isn't so. Only the monitor on thunderbolt port shows the intel logo.
First attempt:
1. Port 1 > Thunderbolt > Monitor USB-C to DP Kabel > OK
2. Port 2 > HDMI > Monitor HDMI to DP Kabel > Screen is black.
I used this cable at the thunderbolt port: SON X-UCC021-010: USB C Stecker auf DP Kabel, DP Mode, 4K60, 1 m, weiß bei reichelt elektronik
Second attempt:
1. Port 1 > Thunderbolt > Monitor USB-C to DP Kabel > OK
2. Port 2 > HDMI to DVI Kabel > Same Problem > Screen is black
I used this cable at the thunderbolt port: SON X-UCC021-010: USB C Stecker auf DP Kabel, DP Mode, 4K60, 1 m, weiß bei reichelt elektronik
Third attempt:
Disabled CEC on HDMI in Bios
1. Port 1 > Thunderbolt > Monitor USB-C to DP Kabel > OK
2. Port 2 > HDMI > Monitor HDMI to DP Kabel > Screen is black.

Fourth attempt:
Enabled CEC on HDMI in Bios
Fix Grafic Output 1 to Thunderbolt and 2 to HDMI in BIOS
1. Port 1 > Thunderbolt > Monitor USB-C to DP Kabel > OK
2. Port 2 > HDMI > Monitor HDMI to DP Kabel > Screen is black.

Fifth attempt:
Enabled CEC on HDMI in Bios
Fix Grafic Output 1 to HDMI and 2 to Thunderbolt in BIOS
1. Port 1 > Thunderbolt > Monitor USB-C to DP Kabel > OK
2. Port 2 > HDMI > Monitor HDMI to DP Kabel > Screen is black.

I have no more Ideas. Which setup will work?
I need a quick solution.
