NUC8i7HVK - Can't Boot with DP Cables Connected

[TCBlueNY]

Hello

I have a NUC8i7HVK connected to two monitors via mDP to DP cables. Works awesome. The problem is I cannot boot/reboot with the monitors connected. I have found some info that this is because of pin 20 being powered on some cables. I've tried diff cables (Accell, Dell, Silkland) no joy. Is there some kind of fix for this? Update or known good cables with pin 20 not powered?

System

NUC8i7HVK BIOS Version 0067

Radeon RX Vega M GH 30.0.21017.1000

Win10 Pro 21H1 (10.0.19043)

2 x mDP to DP cables

2 x Viotek NV32Q Monitors

-Thank you

Hello @TCBlueNY

Thank you for posting on the Intel® communities.

In order to understand better the scenario and the issue, could you please provide us with more details?

1- When you said the "Intel NUC cannot boot", do you mean it cannot boot just to the operating system (OS) or is it not even able to access the BIOS?

2- Does the issue occurs 100% of the time you try to boot? Or does it happens randomly?

3- Are you performing any process/workaround to be able to boot the Intel® NUC? (e.g.: unplugging one of the DP monitors, using an HDMI* monitor, etc).

4- Also, we noticed the system is running a previous version of Windows* 10 (21H1). Could you try to update to the latest version 21H2 (19044) to see if the issue is fixed? Refer to Update Windows*.

5- We understand you have tried different DP cables. By any chance are you able to test with different DP monitors?

6- If the issue persists after updating the OS, please provide an Intel® System Support Utility (Intel® SSU) report to gather more details about the system:

• Download the Intel® SSU and save the application on your computer
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click Next and click Save.
• Once you have saved the file (.txt file), please attach it to your reply.

To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.
