I understand you are having problems when setting up Dual Monitor with your NUC unit. I apologize for any inconvenience this may be causing. Regarding this issue, I would like to start by gathering more information about the system. To better assist you with your request, I will need to check some information about your computer. Please follow these steps:
1. In the keyboard, press WinLogo key + R.
2. In the Run box please type dxdiag and hit Enter.
3. Click on Save All Information (save it in your desktop).
4. Attach to this thread the report.
To attach a file, you must click "Use advanced editor" in the top right and then click the “Attach” option on the bottom right hand the response box.
Also, please bear in mind that Intel® does not recommend the use of any kind of adapters. This is because we cannot test all of them, so we cannot guarantee that these are going to work. We can recommend you to update your graphics driver, that in some cases will fix the problem.
I hope to hear from you.
Thanks for your reply.
Attached you'll find two reports:
1. DxDiag-HDMI2DVIPort.txt > dual monitor setup working (Connection of 2nd monitor HDMI 2 DVI Port)
2. DxDiag-HDMI2DisplayPort.txt > dual monitor setup NOT working (Connection of 2nd monitor HDMI 2 Display Port)
Thank you for your response,
I can see in the DxDiag sent that you do not have the latest graphic driver installed yet. Being this the case the first option will be to update it to the latest version. Also I was able to determine that you are currently using the "Fall Creators" update of Windows, and the latest graphic driver release was released to fix any problems related to any kind of graphic problem with that update.
Nevertheless, as mentioned previously, you are actually using adapters and we cannot verify nor confirm if a graphic driver update will fix the problem you currently have. It is also recommendable for you to try a different cable and attempt the connection again, you can also refer to the following link to see the different tested peripherals that are known to work with your unit, specifically under "Adapters and Dongles":
I hope you find this helpful.
