So I spent a bit of time in the community forum reading about screen flickering with the 7th Gen NUC's about a year ago. It must have been resolved for a lot of people cause it seems to have vanished as an issue from the forums here.
However I've been dealing with this incessant problem ever since then. I didn't really mind too much, as all it required to fix the flickering was to re-plugin the HDMI cable, but that doesnt seem to be helping anymore. It's definitely getting worse.
I've had my NUC hooked up to a Samsung KU6000 UHD TV since the start. I also had a replacement unit sent after a BIOS update bricked my first unit - still same issue. All my drivers and BIOS are up to date. I've also tried multiple HDMI cables, although I haven't had the opportunity to try a different display (all I have is a laptop).
It seems to be worse when video is playing from any media application, especially PowerDVD which I use the most.
Any help with this would be really appreciated. :)
This is already my second unit with issues :( , I'd be pretty frustrated if I had it replaced only to have a third unit with flickering as well.
I'm sort of hoping I can find another avenue before resorting to yet another RMA.
I needed to replace it two times. The third unit then worked like a charm for months until I replaced it with NUC8 which is also faulty as the Ethernet port is dead. Unfortunately the NUCs have a massive reject rate but when they run fine, they make so much fun to work with so I would recommend you to get rid of it and try a third one.
Any Intel Staff care to provide some input about this?
I'm still struggling with the issue, and if I can't get it resolved I'll be having to try for another replacement.
So I seem to have resolved the flickering by rolling back the Intel Display Driver version by one to 126.96.36.19929.
It definitely is a lot better - - It was flickering almost every couple of minutes earlier.
I'll keep an eye on it the next couple of days, and if the problem persists I'll post back here.
I've been away for the last few days so I've had little time to test. However I installed the Windows 1809 update which I had been postponing up until now, and that with the previous display driver seems to have solved the issue. It also addressed the HDR lag issue I was having with Netflix.
Like I said though I have been away so I've only tested two movies so far, but I'll give it a more thorough test in the next few days and will update you.
It's a problem with all of these NUCs. I spent many months invested in troubleshooting the graphic problems with all 7iXBNH nucs.
1) upgrade HDMI/DP firmware using tool linked. https://downloadcenter.intel.com/downloads/eula/26609/HDMI-Firmware-Update-Tool-for-Intel-NUC-Kit-NU... (i believe you do need HDMI hooked directly to TV for this update to work)
2) For playback, do not use the HDMI port, use a USB-C to hdmi adapter.
2) use intel driver https://downloadmirror.intel.com/28289/a08/win64_188.8.131.5273.exe nothing later will work, they all flicker. (assumes win10 1809 x64) do not use any of the DCH drivers.
3) if you are passing 4K HDR through a receiver please make sure it supports 2160p @ 60hz 10Bit HDR.
disable windows 10, driver updates or it will replace your driver with a DCH later version and you will have the flicker back again.
Mine has seemed to stop flickering with the Win10 1809 update, but if it occurs again I'll try these steps. Thanks.
Just to clarify though. The display driver you linked is not available on the NUC7i5BNH drivers page. Does that have something to do with it not being a DCH Driver?
Okay so after updating to Win10 1809 and then installing the latest (advertised) 184.108.40.20686 display driver, the flickering has almost entirely stopped.
Every now and again I'll get a little flicker - mostly when changing between fullscreen apps, but the problem seems to be pretty much solved in most cases. I'll run this system configuration for now, and if anything occurs again I'll try the troubleshooting tips provided in this thread, or come back here.
The driver I linked to is the latest driver for the graphic chipset that works. It is not DCH and also not approved for the NUC, which is why it is not listed directly under your NUC downloads. None of the DHC drivers will work without flicker.
I've found the best luck with the driver I linked to you.
If you're using a samsung screen I highly recommend using the firmware update tool on the DP chip as linked above (follow the instructions in the readme).
1809 here with the above driver and firmware, no flicker or audio dropouts whatever. I do not use HDMI because it had dropouts and use a USB-C to HDMI adapter to get around the HDMI problems.
I already have the latest firmware for HDMI/DP, but these are some useful steps I can follow if the screen flickering becomes as bad as it was before the Win10 1809 update.
For now it seems to be behaving itself with the latest DCH display driver. So here's hoping it continues.
