    New Intel NUC7i5BNK couldn't get HDMI to work

    TomAm

      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.

          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

       

      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.

          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

       

      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 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

       

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