Thank you for contacting Intel Communities.
The DP output was eliminated because the USB-C is also Thunderbolt 3.0 compliant, that also acts as DP 1.2 rev.
Please bear in mind that KVM devices are considered adapters since they are between the Intel® NUCs and the displays, so this could be a compatibility issue; I recommend using a Cable/Dongle from this list.
I hope this information helps.
thank you for your answer. Two comments from my side:
- When I want to connect a displayport monitor the USB-C (and thunderbolt) port is blocked. Not good. The only option I see is to spend another $200 to buy a thunderbolt docking station. Would this work? I was looking for a HDMI 2.0 to displayport adapter like the one listed on the Intel webiste, but these cannot be purchased, at least not in Germany.
- Having a KVM device is not so 'exotic', at least not for a software developer. Plenty of hardware on the desk. There is no KVM switch on your list. Does this mean, that I cannot recommend your NUC 7i7 for this scenario? The company I work for (just about 8k people) would love to hear this...
Please find a solution, all other NUCs I have (5i5, 6i7) work in my setup, it is just the 7i7 which fails miserably..
What is the model of the KVM you are attempting to use?
KVM Switch ATEN CS1924 (4K Displayport switch)
Works pretty good, first available DP 1.2 KVM switch, also has USB 3 switching
Wow, that's an expensive switch! US$562 That's 4x what is cost me for my 4-port USB2 1080p HDMI KVM. I will have to watch for the price dropping as the market matures...
I tested the following:
- Intel® NUC Kit NUC7i7BNH (with BIOS version 0046 - Date: 05/03/2017)
- Windows® 10 with Creators Update.
- HP Z27s monitor.
- Club3D USB 3.1 Type C to DP adapter
I restarted the Intel® NUC and I got video signal again.
This confirms that the issue is related to compatibility between the KVM and the Intel® NUC.
My recommendation is to contact Aten Support to look for any compatibility information.
I hope this helps.
