Brand new NUC7i5BNH purchased in September, immediately upgraded to BIOS 0052. Clean install of Windows 10 and latest Intel drivers including graphics 15.46.05.4771. Connected via USB-C to Displayport cable to Philips BDM4065UC 4K monitor 3840x2160 60Hz.
I get the screen going blank issue as reported here, and also the monitor constantly being woken up from sleep when the windows session is locked.
No problem using this monitor with my desktop computer at 4K 60Hz via Displayport cable for nearly two years, so yes there is something wrong with this NUC.
I'm still seeing mixed results with BIOS 52 and the _BN driver.
I've seen a resync and, for the first time, a narrow band of rainbow "snow".
It seems like it's better than before but still not 100%. Get back to work INTC!
As listed elsewhere, I'm using a NUC 7i5BNK + StarTech cable + Acer B286HK 4K/60Hz monitor.
All was working _rock solid_ for months before this problem appeared.
I have been following the forum for a number of weeks now.
My NUC still has flickering issues at 4K 60hz, even after installing the new BIOS en driver suggested in this thread NUC7ixBN Screen Flashing (screen turns on and off) when using 4K resolutions
Why did Intel support close this thread and want everybody to send a private message to intel support?
Did they stop investigating this issue?
I would like to know as well if this is still being investigated.
I still have the flickering issue with my Denon AVR-3200W and Philips 55PUS7181 TV with the latest drivers on my NUC7I3BNK suggested in this thread.
In 05/2017 it was working like a charm and i never changed the hardware or cables. Only did a BIOS upgrade and graphics driver update in 08/2017 and have this problem ever since.
all the time : In the last 2 month i switched alot between driver .4664. and other drivers to find the best solution for myself. So each time i switch driver, the flicker issue is back. So i started to uninstall old graphic driver/software and installed it again (i didnt just overwrite the existing driver/software stuff). I repeat that progress until i dont have any flicker issues anymore. This method works for me all the time, just the amount of tries of reinstalling i need is changing " most of the time its 2-4 times.
sorry not sure how to say it correctly in english but i hope its good enough to understand
To completely remove the driver, I recommend using the display driver uninstaller utility found here:
Before using that, when I would uninstall the driver in the Device Manager, it would just reinstall a minute or so later without any interaction on my part. If you use the display driver uninstaller then reboot, that shouldn't happen. Hopefully that wipes out all traces of the old driver and the 4771_BN will work for you.

Well apparently Intel didn't like my previous comments and therefor banned my account. Or cvare did it.
Anyways, I do not care. What I do care is about poor products.
As mentioned before in my other posts, is that I asked Amazon.de for a RMA. They accepted my RMA and send me a new NUC. Ofcourse it's the same one I had before: NUC7I5BNH.
Anyways, this one had the production date May 2017 (one month earlier than the one I had before).
It came with an older BIOS, which I didn't flash straight away this time. And guess what. It works...
I can now install the latest graphic driver without my screen flickering or not turning on anymore.
Here is the BIOS I am using now (which was already on the NUC): https://i.imgur.com/hBJpWay.jpg
The BIOS which is installed is: 0042
Here is the proof I installed the graphic driver without issues: https://i.imgur.com/MjUdD1e.jpg
It's the latest graphic driver ending with _BN. But I doubt the driver is the issue.
So I can only conclude two things, based on my own experience:
a) my previous Intel NUC was already a bad unit, because of the problems I experienced.
b) the BIOS updates caused all the issues I experienced, because the 0042 doesn't give me any issues.
I still find it pathetic that I was banned from the Intel forums, though I am a customer and I want to be treated that way.
If the product was good to begin with, I would never have posted anything badly in regards to this product and the "service" Intel provides.
Anyways, I can only recommend send back the Intel NUC you have to Intel or wherever you bought it and get a new one (hopefully with the same BIOS as mine).
I left my computer on for several hours and no issues at all. Probably I will be banned again by Intel or cvare, because they will clearly do not like my messages or the information I have provided.
I wish you all the best of luck with your units and I can only hope that you will experience a problem-free Intel NUC as I am doing now...
PS: I did write several emails (how customers are treated on this forum) to higher ranked persons within the Intel corporation, but I doubt they will take action at all. They simply do not care about customers.
Now 8 days have passed and still no issues whatsoever anymore...!
Everything running perfectly. I am really glad that I decided to RMA the Intel NUC and get a new one and not updating the BIOS. :-)
I wish you all the best of luck with your NUC and with Intel ofcourse. I doubt this will ever be fixed. They should release the ability to downgrade your BIOS.
And if that's not possible. RMA your Intel NUC and get a new one and hopefully it will have an older BIOS.
