NUC6i7KYK with Display Port 1.2 (MST)

I have a NUC6i7KYK (Skull Canyon) device and it seems like the latest (and not 'greatest') drivers/firmware have taken a huge step backwards.

Basically, the device is not usable with the configuration I need (and is 'less' than what it is advertised' to support).

Machine is running Windows 10. The video's and info file is from the Insider Preview, but the problem occurs on 'Plain Vanilla' Windows 10.

Setup

HDMI : Dell U3014 (2560x1600)

DP : Dell U3014 (2560x1600) -> (MST) Dell U3014 (2560x1600)

Problems:

  1. The display on the HDMI port is 'unstable'. Various drawing artifacts occur during composition. (Smooth background fade is the easiest to observe.)
  2. Support for ANY of the monitors off of the DP connectors result in 1-3 second 'device resets' for things like moving the mouse on the display.

These problems occurred in nearly the same way with my NUC5i7RYH when it first arrived. (Subsequent firmware fixes and driver updates have made this machine usable.)

For comparison this is similar actions using the NUC5i7RYH:

There have been several reports of the Intel® NUC Kit NUC6i7KYK having Graphics stability problems when connecting more than one high resolution monitor.

We have found that one specific type of memory, Corsair 32 GB (2 x 16 GB) CMSO32GX4M2A2133C15, has an incorrectly programmed SPD. The SPD data is not correct. TRFC (byte 31 and byte 30) are set to A0F0 and instead should be set to 0AF0. This would cause instability, monitor flickering and monitor blanking.

Thanks for letting us know what's going on ErnieE, I surely see the flickering in the video that you're referring to, very strange.

We've tested every known configuration on KY, and of course we can't test every monitor, but never had an issue.

I apologize if you've mentioned this already, but what monitors are you using exactly? Also, what BIOS? I'm assuming you've installed all the latest drivers?

We just so happen to have 2 Dell 3014T monitors here in our lab, and I hooked them both up, played a couple 4K videos streaming from Youtube for a while and had no issues.

We just today released BIOS 0037 (if it's not up as I type this it will be by tomorrow), I would say try that, and if it doesn't fix the issue, then https://customercare.intel.com/ RMA your unit.

Sigh,

Firmware (Bios 0037 see photo), Drivers 4463.

ALL of the displays are Dell U3014. From left to right the connections are | mDP (MST) | <---- | <strong>DP | HDMI

I guess I am not sure WHAT the heck Intel is thinking. I don't know what (if any) between a NUC6i7KYK and NUC6i7KYB is. (I supposedly purchased the former.)

Firmware and driver update, the system is still unstable with more that a single Display attached.

The first video is streaming one of the uploaded 720p videos from YouTube. When playing video content, the performance is by FAR the worst.

When you take the HDMI display out of the equation, the problem becomes 'just' the blank screens,

A single DP (or HDMI) ~seems~ stable, but the unit is next to useless for me with only a single display.

The RMA was created and ICS contacted me this morning, however:

and if it doesn't fix the issue, then https://customercare.intel.com/ RMA your unit

 

 

Hello Ernest, Thank you for contacting Intel Customer Support. I understand that you need .

 

Sign in at https://customercare.intel.com/ICS_CommunityCaseDetailsPage?lang=en-Us&id=500U000000Vhyl9IAB customercare.intel.com to view and update your request or to get additional information.

Single Sign-On Error

We can't log you in. Check for an invalid assertion in the SAML Assertion Validator (available in Single Sign-On Settings) or check the login history for failed logins.

So I can't even elect to PAY for cross shipping to get a device (which I have serious doubts will fix the problem, but I am willing to play along at the moment) shipping ASAP.

This is really getting pathetic. As a 'direct to consumer' producer Intel is doing its best to make me unhappy (read: highly likely to avoid purchasing OR recommending Intel consumer products).

As an early adopter you kind of expect a ~little~ annoyance, but well over a month and three Firmware + 2 Video driver updates and I still have a 'brick' for what I need the unit for. I might not even be AS angry if (like with my first NUC) the unit was just a test and being able to use a single monitor was only mildly annoying. However, after the driver and firmware updates that unit has become (mostly) reliable. I can live with the annoying way that my desktop collapses and it loses track of displays on the DP connector after sending a signal to put them to sleep.

I was checking this thread and wondered, were you able to replace the unit as a troubleshooting step for this matter?

 

 

Hoping I can hear from you about how it went 🙂
