New Intel NUC7i5BNK couldn't get HDMI to work

[TWehn]

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: https://www.reichelt.de/USB-Grafikloesungen/SON-X-UCC021-010/3/index.html%3FACTION%3D3%26GROUPID%3D8275%26ARTICLE%3D213315 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

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.

Hello TomAm,

Thank you for joining the Intel Community Support.First, I would like to gather some information about your setup. Follow these steps with both monitors connected:1.Open the Control Panel for Intel® Graphics2.Locate and save the graphics driver report: Intel® HD Graphics Control Panel > Options > Dropdown > Information Center > Save.3.Attach it to the thread. Second, do you experience the same issue when you use a straight-through connection (HDMI-to-HDMI) with a single cable?Is it the same when using single display only?Wanner G.

I can't try the option HDMI direct to HDMI.

Because my monitors do have only DVI, DP and SUB-D.

Now i have tried following options:

First:

Shiverpeak HDMI > DVI Adapter > DVI-DVI Kabel > Works!

https://www.reichelt.de/A-V-Adapter-HDMI-/SHVP-77400/3/index.html?ACTION=3&LA=446&ARTICLE=211245&GROUPID=5385&artnr=SHVP+77400&SEARCH=dvi%2Bhdmi%2Bshiverpeaks&trstct=pos_5 SHVP 77400: Adapter, HDMI Stecker auf DVI Buchse bei reichelt elektronik

In attachment is now my working option file!

Second (better): 

UGreen HDMI to Displayport Converter > DP to DP cable > Works!

See pictures in attachment

Third (better and cheaper):

Now i will buy for a test this cable:

https://www.reichelt.de/HDMI-DVI/SHVP-BS77488/3/index.html?ACTION=3&LA=446&ARTICLE=218238&GROUPID=8098&artnr=SHVP+BS77488&SEARCH=dvi%2Bhdmi%2Bshiverpeaks&trstct=pos_13 SHVP BS77488: HDMI Stecker < DVI-D (24+1) Stecker vergoldet 10 m bei reichelt elektronik

HDMI to DVI direct. Because the adapter needs to much place behind the nuc.

Thanks for your help!
