NUC7i7BNH loses video after samsung HDMI 2.0 TV is shutoff / turned on again

So the title says this pretty well. I had exactly the same problem before I shifted from Linux to Windows 10 for an HTPC. As soon as the TV shuts off the Intel NUC loses connection (via HDMI) to the TV and when the TV comes back online it stays blank until the HDMI cable is physically unplugged / plugged back in.

It's running the latest drivers pack from Intel but I don't think that's the issue, as both linux and now windows exhibit the same problem. I've tried two NUC7i7BNH's, both of which experienced this identical problem so I suspect it's very likely protocol handling problems between two HDMI 2.0 devices.

It's possible that there's something up with the TV however none of the other HDMI devices connected to it are experiencing this problem.

Does anyone have any suggestions on what to try here?

Do you have a receiver to try with as a go between device? If not and the tv has multiple hdmi ports try using a different port.

And check out the updates. There is a hdmi related update but what it does escapes me now.

Hello cfaber,

Thank you for joining the Intel Community Support

Having the latest Intel® HD Graphics Driver and BIOS update installed may help you fix the issue.

For this reason, I would like to gather basic system information. Please scan your Intel NUC using the Intel® System Support Utility. Follow the steps below:

 

1.Download the Intel® System Support Utility and save the application to your system here:

https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- Download Intel® System Support Utility for Windows*

 

2.Open the application and click Scan to see system and device information. The Intel® System Support Utility defaults to the Summary View on the output screen following the scan. Click the menu where it says summary to change to Detailed View.

 

3.To save your scan, click Next and click Save. You can save the file to any accessible location on your computer.

 

4. Attach the report to this thread.

Thank you jema for your helpful suggestions. In fact, I will be providing additional information about the HDMI 2.0 firmware update after reviewing system information.

I look forward to hearing from you .
