There were at least two driver updates since I started having the problem - the most recent update was 8151 - but I have to roll all the way back to version 7529 (dated 11/13/2019) to get rid of the problem.
I have a NUC8i5BEH and have exactly the same issue with any Intel graphics driver later than 7529. I'm sure we're not the only ones, but 7529 is the latest driver offered by Windows Update so I would imagine most users would still be using that. Do you connect your NUC to your monitor using Displayport? I do and found with drivers later than 7529 when the monitor turns off it keeps coming back on, after a couple of seconds and cycles continuously. I had to swap it for an HDMI cable and that worked fine - but I still have the display wake-up problem each morning.
I connect via HDMI. Do you happen to be using a Dell monitor and their software?
Regarding 7529 build... there was even an update that specifically said "will solve wake issues"... but it didn't. Seen all kinds of suggestions about turning off FastBoot, turning off HIbernate mode, disabling Link State Power Management... none of them work. any driver after 7529 causes the screen wake porblem.
Re: Dell DisplayMate just curious because the "flashing" issue I saw at one point but in my case this was Dell DisplayMate. Uninstalling it resolved.
My guess is that whatever the problem is, it happens when the PC attempts to sleep, as the PC itself is awake, though the monitor isn't. I can even RDP into the machine, but I see a black screen... which tells me it's the display driver.
Thank you for posting on the Intel® communities.
Please run the following tool and attach the report generated.
1. Intel® System Support Utility (Intel® SSU)
- Intel® SSU Download link
- Open the application and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View". \
- Click on the menu where it says "Summary" to change to "Detailed View".
- To save your scan, click on "Next", then "Save".
I would like to confirm the following:
- Are the monitors straight connected with a single cable that has the same connection type in both ends?
- Does this behavior happen using any video port of the NUC?
- So taking in consideration that this behavior does not happen with driver version 7529 and it happens with any new driver I was wondering if the same happens with this latest driver for this NUC 220.127.116.1185? please confirm it.

The continual cycling of monitor on and off after 10 minutes (the time set in Windows power settings) only happens when I use a USB-C -> displayport cable. If I switch to an HDMI cable the problem goes away. The inability to come out of sleep mode after a long period (like overnight), however, happens with either cable. I confirm the problem is there with 18.104.22.16885 and 8141.
Same experience here as far as 7985. I would add that Intel Driver & Support Assistant is rather inconsistent with itself (it shows 7529 as "up to date") and with Windows Update (which was stuck in a loop installing the same driver over and over again - so I disabled driver delivery via Windows Update.
Will post an SSU ASAP.
Thank you for the information.
We will take a look into this, please allow me some time to update the thread.

I'm having the same problem now, after having updated the BIOS to 0081 on 7th June, 2200 hrs. My Panasonic TV won't show any display once display goes off, as per settings. My NUC's HDMI is connected to my Yamaha Receiver, which provides my Panasonic TV a passthrough via another HDMI. Have had to force shutdown my NUC at 3 different instances because of this. For the time being, I've had to change my Win 10 power settings to 'never'. Please help!
I am really sorry for all the effort that you have gone through dealing with this issue, we are aware of it and currently working on a solution but this may take some extra time.
@Ronny_G_Intel, I just wanted to add that I’m also having the same issue on my NUC 8i7BEH but mine is running Linux, so this seems to go beyond Windows. I never used to have this problem it’s recent within the last month or two.
I’m going to start a new thread with additional questions so that I don’t hijack this one but wanted to share the info since the issue is still being worked on. Right now, I have to use the power button to completely power off and restart just to get my display back.
I use an HDMI to HDMI cable connected to a Vizio P-Series TV.
