Just wanted to add that the problems are not just on 4K resolution, I would say it is worse on ultrawide 1440, please see the nuc7i5bnh driving the Predator X34 through HDMI below
I noticed the issue within two days of receiving my Nuc7i7bnh.
It seems to manifest itself in two different ways.
If I am using a Thunderbolt (usb c) to display port cable
I get black screens every few minutes. The phenomena seems to be more apparent under two conditions:
1. Rarely happens within the first five minutes after I turn on the Nuc. However, as the machine warms up it begins to happen every few minutes.
2. Graphically intense websites trigger the issue as does high definition videos. When I open a 4k video the black screen issue generally starts immediately along with a burst of weird screen corruption.
If I am using an hdmi cable
Once the system goes to sleep it is unable to wake up and display to the monitor. The only solution is to reboot the system.
I know several others here locally that are having the same issue. So the issue appear to be widespread.
Intel Nuc 7i7bnh
Dell P2415Q monitor
Crucial 32GB DDR4 2133 MT/s
Samsung SSD 960 EVO NVMe - M.2
Keyboard/Mouse - Dell KM717 bluetooth connection
Thanks guys for the updates and info. I'll let the debug team know.
I'm not sure this will help, but for what it's worth...
I had the display flashing immediately after upgrading to BIOS 48. Down graded to BIOS 47 and the flashing went away completely.

I just did a format c and now with standard ms vid driver i can confirm no black screen ( run sound through bluetooth).
Not the smoothest 4k youtube vids but no blackouts, no green boot screen and no weird irrie sounds from my sub (yay)
Weird that it runs at 64Hz only now
i allso got the intel nuc nuc7i5bnh. and as many in here i got the flickering screen to black problem and as one other ive read ive had the green boot problem.
i just reinstalled windows 10 version 1703 ( OS Build 15063.0 ) atm i dont have any flickering problems it looks like. I allso have the flickering on the basic driver thats installed with windows 10
my nuc is connectet via HDMI to a lg 43uh650v.
Just installed this driver Download Intel® HD Graphics Driver for Windows® 10* for Intel® NUC Kit NUC7i3BN, NUC7i5BN, and NUC7i7BN and rebootet and it gave me a green boot screen for now no flickering to black
i seen some of you postet some files for intel to look at using a program. what program is that ??
Flickering also when switching between different software windows and scrolling up/down on a webpage, as well during playing the video.
Win10, NUC7i7, HPEnvy 27s, HDMI2.0 and the latest drivers etc.
Thanks all for the feedback.
The issue seems to manifest in different ways for different people, so all we can do is share what we've seen in our own environment, regardless there's an issue and we're working with the GFX team to figure it out.
PLEASE, keep this thread to this ONE issue only. Open a new thread if need be so we can focus on just this one issue. Thank you.
I also have an NUC7i3BNH and have the flickering only at 4k 60hz. If I change it to 30hz I do not get the issue.
I have tried multiple HDMI 2.0 cables. If I plug my AMD Ryzen gaming RIG into my setup I get no problems.
Guess what I will be getting if I RMA this device (which is likely)...Mini-ITX Ryzen 3 build. Bet you I wont have issues.
Spent many hours on this and very angry.
Completely understand your anger and frustration. I would be quite upset as well.
As of now if you use the .4664 driver, posted above, the issues are minimized/gone, and we are working on a fix, but you have to do what you have to do and we understand that.
Thank you for taking the time to let us know and I will post any updates we find in this thread.
Sorry but before the world starts thinkin the .4664 is a working driver ...... It is not..
Are there no older drivers we can try ?
This is becomming silly , been a few weeks now and nothing from intel yet...i have chinese FANLESS boxes the size of a cd case running win10 4k better then this nuc
Expected more from a compagny like Intel.
Thanks for that before I wasted more time.
For a Box that promotes itself for 4k 60hz and it not to work is just really poor in my mind.
It will just take a few seconds to install and it will work ...at 30Hz tho
Had a clean windows running "flawless" with the standard ms vga driver but needed intel gfx driver to run some apps.
The trouble begins after installing intels(4664) driver on the first reboot it started with a white noise screen.
I'm experiencing similar problems as described by azguy, but in my case with USB-C to HDMI-converter I have far less problems and blackouts compared to direct HDMI -> HDMI connection.
Windows 10 Creators Update
BenQ PD3200U @ 3840x2160/60hZ
Graphics driver .4729
With direct HDMI -> HDMI connection I get constant blackouts. Problem seems to get worse when the NUC is warming up as described by azguy. Also I experience graphically intense websites seem to worsen the problem but I also get blackouts when swiching to Windows settings.
With HP USB-C -> HDMI converter I have far less problems and didn't notice any blackouts but still get occasional screen distortions.
I have tried several HDMI cables and didn't notice any difference in behaviour so the issue can't be in the cables.
I've also tested with a BenQ SW2700PT and get no blackouts through HDMI -> HDMI and when using USB-C -> HDMI converter also can't notice any blackouts. The difference is the SW2700PT doesn't have build-in speakers, therefore to me it seems likely audio over HDMI could be an issue together with the higher resolution of the BenQ PD3200U.
I'm too hoping for a a quick resolution since I don't want to loose the USB-C connection just to get a stable screen.
So far you're the only one reporting issues with .4664, at least major issues.
Is anyone else having problems with .4664?
