NUC6CAYH: VGA black scr 1-2sec / HDMI flickering: We need a solution

November 16, 2017, 7:30 am

I work about 15 years in IT, mainly as a Windows server specialist, but also desktop support / integration and software testing.

Since they first came out, I've been using and recommending Intel NUC's, by now I've installed about 30 of them, mostly with very happy customers as a result.

 

About the NUC6CAYH..

Recently a client of mine needed some simple Windows 10 pc's with a VGA connection, so I installed 3x NUC6CAYH.

The NUC's have very different production dates, yet ALL of them have the same issue of 1-2 seconds of black screen, sometimes as much as every 2 minutes.

After trying everything (changing screens, changing cables, trying different BIOS versions, trying different graphics driver versions, ...), without any result, I discovered on this forum that a lot of users are experiencing the same issues.

An issue like this is not something I would expect in a 2017 product (especially coming from Intel).

 

The client bought new screens with a HDMI connection, only to find out this also gives flickering every few minutes, again, on ALL of them! (the screen doesn't go completely black as when using VGA, it's less severe, a kind of fast flicker).

Needless to say this is a very disappointing experience for both my client and me.  Not to mention the cost of troubleshooting, only to find out it's a faulty product.

 

This looks like a design flaw, I can't believe Intel is still selling these!

Probably only a few % of the people with this issue will find the way to this forum, so that means a huge amount of frustrated customers will hesitate to buy an Intel product again.

 

I'm sure Intel knows exactly what the issue is, they should, after all these months and probably thousands of these units returning.

 

So my question is:

To other NUC6CAYH (with Windows 10) users:

Is there anyone here who's problem was actually completely solved (Please specificy if you use HDMI or VGA) if yes, which actions did you exactly take?

 

To Intel support:

As this issue seems so widespread, please tell us what the root cause is.  If you're not aware of the root cause, please escalate this to the right engineers to troubleshoot.  My feeling is that this specific issue is causing damage to Intel's good name, not to mention the huge troubleshooting costs for all people still buying this product.

Is there an actual solution? Will the problem be 100% solved with a replacement from Intel?

 

 

Thanks!

NUC7i7BNH 3x Display Support

Hi,

 

We've purchased a NUC7i7BNH and we're trying to use 3 monitors with it based on the assumption in the spec sheet that 3 displays are supported on a Windows 10 Pro 64-bit install.

To try and achieve this we've also purchased a Thunderbolt 3 to dual HDMI Adapter from Startech - Thunderbolt 3 to Dual HDMI Adapter - 4K, 30Hz | Video Adapters | StarTech.com United Kingdom as we would prefer to use HDMI monitors over DisplayPort monitors - unless of course this is not technically feasible.

 

Unfortunately, i'm not getting the results that I initially expected; I always get video on the built-in HDMI port, however I only seem to get a single video output on the Thunderbolt 3 adapter, even if there is no display connected to the built-in port. I'm only ever seeing 2x Generic monitors in device manager.

I don't think it's an issue with the adapter as I've been able to swap the cables over and still see video on the same monitor, but on the other port, however i'll also check in with tech support at Startech to see if there is anything they can suggest in the meantime.

 

I have tried updating the graphics drivers, installing the Thunderbolt 3 drivers and updating the BIOS.

 

I've done some digging and this page: https://www.intel.co.uk/content/www/uk/en/support/articles/000025672/graphics-drivers.html  seems to suggest that the graphics card supports 3 monitors and this page: https://www.intel.co.uk/content/www/uk/en/support/articles/000005571/mini-pcs.html  suggests that DisplayPort daisy chaining is the only option.

The BIOS for the NUC states that it only looks for a maximum of 2 monitors.

 

Am I chasing my tail here? Am I limited to 2x HDMI only and can I only use 3 displays via DisplayPort?

 

Thanks for reading!

USB-C to HDMI adapter not visible

Dear everyone,

 

I am aware about lots of topics about USB-C to HDMI adapters on this forum, yet my situation is a little bit different.

 

What I've got:

     - 2 x NUC7i3BNK (second one was bought 3 months after first one)

     - 2 x i-tec USB-C HDMI Adapter

     - 4 x LG IPS Monitor 22MP58 | Sleek Cut Design IPS LED Monitor

 

Basically I want to have two double-monitor systems.

 

The case is that first NUC works perfectly with both adapters, but second doesn't work with any. After plugging adapter the screen sees something for a moment, but eventually shows "No signal". The OS here doesn't matter, since on NUC number one both screens work also when in UEFI configuration. Tried upgrading BIOS, without any success. Also, I couldn't find any settings in UEFI which could change anything.

 

I'm afraid that buying new adapter would be a waste of money, so my question is - what can I do?

 

Kind regards

my intel nuc7i5bnh was running windows 10 1703. during the restart process of the update, display was lost. tv reported "invalid format". changed tv settings but still no display. then i tried using a computer monitor which worked just fine. but i primarily use my nuc as a htpc, which is hooked up to the tv via hdmi. is there a solution for this? i can do a system restore and revert back to the earlier version but im afraid that windows update would just automatically reinstall the faulty update. thanks in advance!

Hi.

 

We bought a Lenovo USB-C to HDMI adapter, and get exactly no image on the HDMI port (even after setting thunderbolt up as primary Screen in BIOS)

 

From Reddit, I can see that it is not an uncommon issue to not et HDMI on USB-C adapters.

 

Which adapters are tested and confirmed as "working"?

Texture bug?

I'm using a 3D graphic editor program that uses OpenGL.  After updating to the Skull Canyon NUC6I7KYK on 4 machines, this program is now having an issue.

 

Whenever we click a texture it changes ALL the textures in the 3D model to that texture.  Almost like the NUC has a graphics bug that is causing the most recent texture loaded to overwrite all the other textures for display.

 

I have downloaded the latest graphics drivers.  Anybody have any ideas?

NUC6CAYH screen turns black for a second (VGA)

Just bought a NUC6CAYH and installed Windows 10 Pro x64 a couple of days ago. A few minutes after Windows Update had installed the Intel graphics driver, the display connected through the NUC's VGA port started to turn black for a second or two every couple of minutes. During the Windows installation and before the box was connected to the Internet (and Windows was able to do updates), the problem did not exist.

To get rid of this annoying behavior, I started to look for updates and flashed the BIOS up to version 41 (from 38) and installed graphics driver 4849, which was just released a couple of days ago. Unfortunately, that did not solve the problem. I started searching this forum and found that many others are having the same problem. As outlined in other threads, this clearly is a Intel Windows driver problem. As others have tried, I installed Linux (Ubuntu 16.04.3) and I am not experiencing this annoying effect under Linux. So please fix this problem in your Windows driver - I specifically picked this box because of its VGA connector in support of my old monitor. It is shocking to me that a company like Intel is not capable to solve a driver problem that has been reported by so many so often for months.

Intel NUC 7i3BNK boot issue after changing graphic memory size in bios

November 22, 2017, 3:24 am

Hello,

 

I'have an issue with the new intel nuc 7i3BNK received one week ago.

I work with intel nuc kit for several years (since the nuc 3217IYE) and I have configured several thousand.

But since the nuc6i3, i'm facing several issue when i modify the graphic memory size in the bios.

For an example, if this setting is not set by the default value, it won't boot via PXE. that why we didn't qualified the 6i3 and we choose to work with the 7i3 after the 5i3.

 

This morning i received 10 new 7i3BNK.

I plugged the ssd and the memory (the same as the 150 nuc kits donE recently), i applyed the w10 LTSB image disk and i configured the bios to increase memory graphic.

 

the memory used is : Transcend 4GB 2133 MHz TS512MSH64V1H Intel Validated

 

the bios have not the same version as the old nuc7i3bnk produced. This morning it was 046.

The bios values are not the same as usual under Devices>>Video>>video configuration

 

I can set :

IGD minimum memory to 32Mb to 1Gb

IGD aperture size : 32 to 1,5 GB

 

So i have set up the nuc as usual :

IGD minimum memory to 1024

IGD aperture size :1024

 

The nuc didn't boot after that (power button blink)

I had to flash the bios to the latest version (054) with the jumper trick to boot.

But in the bios the video configuration it's still not the same as the last time...

 

IGD minimum memory to 32Mb to 64Mb

IGD aperture size :128 to 1024.

 

I did it on another one and the values are not the same as the previous one :

IGD minimum memory to 32Mb to 64Mb

IGD aperture size :128 to 2Gb

 

i'm very confused about this, did someone encountered the same issues ?

Does intel knoow about this ?

I need the abilities to set 1024mb minimum and 1024Mb aperture in the vidéo configuration.

 

Thank for your help.

HI. Just an update for those using NUC6i7KYK driving VIZIO TV via HDMI.
  The "No video" or "Not Support" (yea this is how it is spelled) issue is gone after the Windows 10 Pro Creative fall update Version 1709 (Fall Creators Update) - Version 1511
    Switching HDMI inputs or turning the TV on/off is fine. Sound issue also resolved.
     Kinda miss my headphones. No one knew when I was playing on my computer. Now they do.
     Thanks to @Scott and others who suggested driver updates.
    Looking forward to the  IceLake  (60W ??) NUC later with 64GB memory support for next Holiday (Christmas)

 

Happy Thanksgiving to all !!

Hi,

 

I have a new 7i5BNH NUC kit that I plan to use for some experiments with Ubuntu. I had a couple of questions:

1) Is there anyway to wire the device for serial output ?

2) I am planning to do some power measurements on this and wanted to know if the DC input jack would be the best place for re-wiring or any other ? Are there any schematics openly available for this kit ? Also, has someone already done this for various idle and active scenarios ?

 

Thanks,

I just updated my NUC7i5BNH with Intel® Graphics driver version 15.60.0.4849, running on Windows 10 RS3 1709, all graphics and gradient colours now display severe posterisation (banding). Display is running DP 1.2 MST 4K 60hz, if I switch the display to DP 1.1 (4K 30hz), posterisation is gone.

 

And I cannot revert back to previous driver version since it's removed from the driver download page.

Skull Canyon NUC no post

My friend owns a Skull Canyon NUC (Intel® NUC Kit NUC6i7KYK) for a short while, but a few days ago she said it didn't turn on anymore and I am not sure what she did. The power button LED doesn't light up, but the fans run very loudly when I attempt to turn it on. I have tried booting it without the RAM and SSD, with one stick of RAM, and different combinations of that. I have tried the BIOS recovery but none of it seems to work. I hope the unit isn't bricked.

 

RAM: Crucial 2133MHz 2*8GB

SSD: Samsung 960 EVO 250GB

 

Any solutions or suggestions would be greatly appreciated. RMA is hopefully the last resort. Thanks.

Hallo,

 

The Intel ME Vulnerability Detection tool said that my NUC6i7KYK

is vulnerable. I updated to the latest BIOS .50 but the Intel ME Firmware

is still vulnerable. Is there any chance to update the Firmware manually?

The ME packs on the support site just consist of drivers and not the FW itself.

Will there be any update soon ?

 

Thanks.

Hello,

 

I have found this little Canon RC6 remote

http://www.eos-magazine.com/articles/remotes/canonrc6.html

 

I was wondering if this could be used to power on (from s5) a Intel NUC6i7KYK Skull Canyon?

It doesn't have to do anything else, just power on from s5.

 

And if nobody has tried, what would be the easiest way to try to do this?

Any suggestions for BIOS/Windows (Pro) 10 settings?

 

Thanks for the help!

NUC7i5BNK - HDMI audio problem with WASAPI 44.1/16

November 24, 2017, 10:37 am

Running Windows 10Pro 64bit Fall Creator's update connected with an HDMI cable to a DENON receiver. I can't get the NUC7i5BNK to output audio at 44.1/16 using WASAPI.

 

Things that I already tried:

  1. Updating BIOS to ver 0054
  2. Updating HDMI Firmware to 1.72
  3. Updating Graphic driver to 15.60.0.4849_BN
  4. Install software guard extensions 1.8.106.40803
  5. Currently using JRiver Media Center 64bit. Updated to latest version
  6. Tried using TIDAL
  7. Tried to output sound through Windows own audio device properties (advance tab). Selected 16 bit 44100 CD quality

 

Basically the problem is such: The NUC7i5BNK is not outputting any sound for 2 channels audio at 44.1/16 when using WASAPI. It will output 48/16, 96/24 or even 192/24 (2 channels) but not 44.1. Strangely enough the applications do not detect any fault, even JRiver displays the audio graphs in main window top and the DSP analyzer window.

 

Switching the output in JRiver to direct sound will return the audio, but then I guess it's because it's being routed through the system audio mixer and probably re-sampled to another frequency.

 

I have no problems with multi channel PCM audio decoded by JRiver or even DD AC3 pass through. It's just 44.1/16 2 channel audio that refuse to play through HDMI.

 

I also tried to output the sound through an external USB DAC and it works flawlessly, so obviously it's not an application problem and is clearly restricted to the WASAPI implementation of the HDMI audio driver.

 

TIA

NUC6i7KYK Not Recognizing Ram

November 24, 2017, 5:09 pm

I have a NUC6i7KYK that has 32gb of ram installed (2x16gb); however, it is only recognizing and using 8gb of ram (two 4gb) in both Windows and system BIOS. It is running Windows 8.1 64 Bit.

 

To troubleshoot so far I have...

 

- Updated to the latest BIOS [KYSKLi70.86A] and reset to default settings

- Updated all drivers

- Removed cards, reinstalled cards, switched cards positions

- Tried one card at a time and both cards register as 4gb of ram (despite being 16gb)

- Windows memory test with no errors found

- Original Nintendo cartridge style blowing on cards (true sign of desperation)

- Checked Windows advanced boot settings to ensure that "maximum memory" box is not checked

- Scoured the interwebs for related forum threads.

 

This Nuc was given to us by Intel's PR services department in exchange for a social media review. Part of the terms of the deal was that it would come pre-upgraded with 32gb of ram. The ram was installed by someone at Intel (probably in Portland) before I ever received it, so one could assume that it is not a compatibility issue. That being said, it was installed with 2x16gb Crucial cards model number: ct4g4sf8213.c8fbd1

 

I personally installed the Windows 8.1 64 bit that appears to run fine with no other issues.

 

Any additional troubleshooting ideas would be greatly appreciated! Thank you ahead of time.
