I just bought a new NUC8i7HVK to use in my home theater but I'm having no end of issues with it.
The all revolve around the AMD HDMI output. I've tried both the front/rear ports, disabling the iGD, enabling iGD, setting iGD to Auto, changing power plans, and anything else I could think of or find on Google and am at my wits end here.
My most recent attempt was to run the AMD Cleanup Utility and install the latest driver from the Intel site. According to the Driver & Support Assistant all my drivers, and the BIOS are up to date.
Further description of issues from most to least annoying:
I'm open to any/all advice. I've probably tried it already but perhaps someone will have something I haven't that proves to be the magic fix.
This is not an answer, but a very similar problem with video signal being "lost" after I KVM over to my work computer for a random length of time. The context is not Home Theatre. I use a Dell U3818DW 37.5" 21:9 Curved IPS KVM Monitor. It takes input from up to four sources and I use two. The NUC TB3 and one of the HDMIs.
This monitor has native TB3 (USB-C), DP and HDMI connections.
No matter what, I have to reboot my NUC8i7HVK when it happens. This is very annoying and I'd like to understand how to resolve it.
Note: I only experience the loss of video signal. Audio is find.
On the NUC, I've tried the HDMI ports, the DP, and the TB3. All demonstrate this behavior.
Like Jon, I am up-to-date on all of the drivers.
I seem to have fixed the black screen issue by doing the following:
I still unfortunately have the audio issues. I had read perhaps they will be solved using a mini DP to HDMI converter so have ordered one to try.
Hello @JBens7 ,
Checking your SSU report, I came to conclusion that you have not installed Intel Graphic Driver. Your have installed the Radeon driver only. So, please download the DCH graphic driver and install it: https://downloadcenter.intel.com/download/28646/Intel-Graphics-Windows-10-DCH-Drivers
Just a follow up after some further experimentation.
I noticed Reliability Monitor was showing Windows Audio Device Graph Isolation continually stopping (crashing)... Then by chance whilst trying to play some audio in Edge on music.google.com I noticed it stopped stuttering if I had the Sound Settings window open. I noticed that was showing microphone input levels. So I tried disabling various parts of the Realtek Audio inputs/outputs but that didn't help. In the end I disabled Realtek Audio entirely and rebooted and my audio is now stutter free! I can even play videos again in Chrome.
So for now I am left with two problems:
Thanks but with the iGD set to Auto in the BIOS the Intel Graphic Driver is not needed as it's not visible to Windows 10. I believe it should be visible to VMs I run but I haven't bothered with those yet.
I had previously tried both the DCH driver you linked and the one detected by the Intel driver scanner tool. Neither of which made a difference to the issues I've been having.
Further to my above notes I have uninstalled the Realtek Audio drivers and let Windows 10 install drivers for that. I now have a working microphone and no audio issues aside from being unable to enable Dolby Atmos.
I'm inclined to leave things well enough alone at this point. I can live without the Dolby Atmos support. I can use my XBox One or nVidia Shield for that. It's a bit sad a PC that's worth more than those combined can't do it, but I'm reminded why I gave up on PC gaming now with the days I've wasted dealing with these driver issues!
I have doubt about your conclusion that the DCH Graphic Driver is not needed. In my opinion it is. This package contains in addition to the Graphic Driver also the Intel Display Audio Driver and also the Intel Graphic Control Center (previously Intel Graphic Control Panel).
When I read the Intel notes in the Intel Graphic Download page, I can read that failing to install this driver may lead to problems you have:
"The primary graphics driver for the NUC8i7HNK and NUC8i7HVK is the Radeon™ driver. If you don't install both the Intel HD Graphics driver and the Radeon driver, you might experience the following problems:
Please allow me to allay your doubt.
1. The integrated graphics are not even visible to Windows 10
2. If I try to install the drivers I'm given the error, "This computer does not meet the minimum requirements for installing the software."
