I successfully updated the HDMI firmware to version 1.77 (https://downloadcenter.intel.com/download/29162/HDMI-Firmware-Update-Tool-for-NUC7i3BN-NUC7i5BN-NUC7...) but now the screen goes blank / black for several seconds, every couple of minutes or so.
I updated the Video Drivers (Iris 640) to the latest version but the problem persists.
I rolled back the firmware version to 1.72 but the frequency of black screen outages increased so I updated to 1.77 again - still the same problem. The black screens are so frequent now that the machine is almost unusable now.
I am connected to an LG OLED 55" 4K via an HDMI 2.0 cable, running Windows 10 Home (version 18363).
If anyone has any ideas or suggestions I would be very grateful for any help.
Thanks Leon, I shall give your suggestions a whirl and post an update.
I may jump to step 3 first since there's less unplugging and plugging involved and steps 1 and 2 would surprise me if they resolved the issue (but hey, I am willing to give them a go).
Oh well... the removal and re-installation of the driver didn't resolve the issue and the problem persists with both a monitor and different HDMI cable.
*sigh* I also realised I hadn't activated System Restore either... so I think it's going to be a fresh rebuild... which, although it is a pain, isn't the end of the world.
Thanks again, Leon.
System Restore/fresh rebuild is a quite drastic solution. I would try first two other solution: Repairing Windows with an in-place upgrade and Clean Boot.
Repair Install Windows 10 with an In-place Upgrade
Thank you for your suggestions.
I admire your persistence... and if you are happy to provide possible solutions then I am happy to implement them :)
I will do as you say and get back to you.
One additional symptom I noted is that if the screen has any type of animation then the black-outs increase in frequency.
Static screens devoid of any movement are mostly stable but the moment you try scrolling or navigating through the screen then black-outs occur.
Strangely though, watching a Youtube video in "default screen" mode provides almost non-stop black-outs but the moment I go "full screen" the black-outs decrease significantly.
Great news Leon,
The in-place upgrade process you suggested fixed the problem - well done that man! :)
Watched the tutorial, downloaded the media creation tool, followed the wizard and hey presto - problem gone.
Yes, you're right - the upgrade process was less traumatic than a total rebuild.
Thanks so much.
Great news indeed. I'm very glad. I would like to add that it is also important to have Bios updated. If your Bios is not updated yet, the latest Bios version 0080 you can download here: https://downloadcenter.intel.com/download/28990/BIOS-Update-BNKBL357-86A-?product=95067 . Download BNKBL357.86A.0080.EB.msi Self-extracting Windows-based update file. Double click on it, and the update will start.
Thanks again Leon. I check the NUC page at least once a month for any relevant updates or new drivers. Agree, BIOS is always something to keep updated.
