How to connect 3 independent displays to the 8v5PNK

2 HDMI displays work fine in any combination of the 2 onboard HDMI ports and via the Thunderbolt 3 port using a USB-C to HDMI adapter.

 

Once I connect to the thunderbolt port, one of the HDMI ports stops working.

 

I've tried both a USB-C to HDMI adpater and the Sabrent TH-W3H2 which is a thunderbolt 3 display adapter.

 

I've installed the thunderbolt drivers from the intel site as well as the thunderbolt control center. The Sabrent device is recognized and works fine, but not at the same time as the 2 on board HDMI ports.

 

Thanks for any help you can offer.

Albert,

I posted this earlier but now see that it wasn't accepted by the site.  Not sure why.  Here's a repeat:

Here are the specs of the cables & adapters I've tried.

Sabrent Thunderbolt 3 Dual HDMI 2.0 Display adapter - TH-W3H2
<https://www.sabrent.com/download/th-w3h2-user-manual/>
Cable Matters USB-C to 8K DisplayPort Adapter 201086
<https://www.cablematters.com/pc-1038-122-usb-c-to-displayport-adapter-usb-c-to-dp-adapter-with-8k-resolution-and-hdr-support.aspx>
Cable Matters DisplayPort 1.4 Cable 102025-6
<https://www.cablematters.com/pc-998-154-displayport-14-cable-8k-60hz-ready.aspx>
Insignia HDMI Cable 20B14T
<https://www.bestbuy.com/site/insignia-4-4k-ultra-hd-hdmi-cable-black/5938403.p?skuId=5938403>

The adapters and cables work when only 1 or 2 displays are attached. 
When all 3 are attached, then the Thunderbolt and main HDMI work, but
not the secondary HDMI.

Hi DKosc, Thank you very much for providing that information.


Besides that information about the cables, could you please provide the model of all the monitors being used?

Also, please attach the SSU report to the thread so we can verify further details about your platform:

Hello DKosc, I just received an update on this matter.

 

In reference to your question, HDMI 2 and Type C Port cannot be used at the same time for multiple display configurations as you can confirm in the following link, at this moment your Intel® NUC is not showing there, but this link will be updated with the information below as soon as possible:

To explain this [Hint, hint Intel: hopefully some text similar to this will appear in their web page], the issue is that, because this NUC supports an Embedded DisplayPort interface, there are only two (other) DisplayPort channels available to support external displays. One channel was routed to the LSPCon IC that supports the HDMI1 connector. The other was routed to both the USB-C connector and the LSPCon IC supporting the HDMI2 connector. This is a smart routing; the BIOS recognizes which of the two connectors has monitor(s) connected to it and makes the routing exclusive to this connector. So, your choices are either,

  1. Connect a display to each of the HDMI1 and HDMI2 connectors. In this case, the USB-C connector will still be available to use for its USB 3.x functionality. Note that you will be limited to two external displays using this connection methodology.
  2. Connect a display to the HDMI1 connector and one or two display(s) to the USB-C connector. Two displays can be connected to the USB-C connector using either an MST Hub device or via DisplayPort Daisy-Chaining. Note that, if the Embedded DisplayPort interface is in use, you will be limited to two external displays as the processor design limits the total number of displays to three.

Hope this helps,

...S
